Portuguese Citizenship by Naturalization

Portugal Nationality by Residency

Portuguese Citizenship by Naturalization: Who Qualifies, and How to Apply in 2026

Portugal citizenship by naturalization is how you become Portuguese by living in the country legally for a set number of years, rather than through a Portuguese ancestor.

If you moved to Portugal and built a life there, this is the route that turns residence into citizenship. This guide covers every part of it: the requirements, where to file, what to legalize, what it costs, how long it takes, and what happens to your children along the way.

The Portuguese nationality rules changed in 2026, and the changes hit this route harder than any other. Portuguese citizenship by naturalization now needs seven years of legal residence for citizens of Portuguese-speaking countries and the European Union, and ten years for everyone else.

The clock counts only from the day your residence permit was issued, so the wait for the permit itself no longer counts.

This is the naturalization-by-residence route, the one for people who live in Portugal. If your path to citizenship runs through a Portuguese parent, grandparent, that is citizenship by descent, which can be faster and usually does not require living in Portugal at all.

One caveat runs through everything below. The 2026 law is in force, but the regulation that fills in the operational detail is still being drafted, so a few mechanics are settled in principle and pending in practice. Fees, exact test formats, and document lists should always be confirmed against the IRN before you file.

Who is eligible for Portuguese citizenship by naturalization?

Foreign nationals who are an adult, resided legally in Portugal for the required years, shows knowledge of the language and civics, and has a clean serious criminal record, and poses no security threat match the current criteria and can become applicants to the Portuguese nationality.

These conditions are cumulative, so every one has to be met at the moment of the request.

The requirement most applicants underestimate is residence. It is now longer than it used to be, and it is counted more strictly than it used to be, so it is worth taking apart.

The residence requirement, seven or ten years

How long you have to have lived in Portugal legally depends on your nationality. Since 2026, there are two tiers.

Seven years for Portuguese-speaking and EU nationals

Seven years of legal residence for citizens of Portuguese-speaking countries and of European Union member states.

Brazilians, Angolans, Mozambicans, Cape Verdeans, and the other lusophone nationalities sit in this tier, as do all EU citizens.

Before 2026 this tier was five years, so anyone starting now should plan for the longer horizon.

Ten years for everyone else

Ten years of legal residence for nationals of all other countries. A British, American, or Indian citizen without a lusophone or EU passport falls here.

What counts as legal residence

Any residence held on a valid Portuguese residence permit counts, whatever the permit was for. The category of the permit does not change whether the time counts, only that it was legal and documented.

The permit types that count

Work, study, family reunification, retirement or passive income, digital nomad, and investment (aka, the Golden Visa) permits all count.

A D7 for passive income, a D8 for remote work, a D2 for entrepreneurs, a student residence permit, a family-reunification permit, and a Golden Visa all build the same residence time: 7 or 10 years.

Student time counts as long as you held a residence permit for study, not merely an entry visa. The point that matters is a valid residence title, kept current across the whole period.

How the clock is counted

The clock starts on the date your residence permit was issued, and the wait for that permit no longer counts.

This is the single biggest 2026 change to the residence route. Time spent waiting for a permit, including under the old manifestation-of-interest system, is no longer added.

Separate periods of legal residence can be summed, continuous or interrupted. They just have to fall within a maximum window: nine years for the lusophone and EU tier, twelve years for the others.

So a gap in your residence does not automatically reset you to zero, provided the periods still fit inside that window.

How much time per year must I live in Portugal to be considered a legal resident and renew my residence permit?

There is no minimum number of days per year for a normal permit. Portugal looks at how long you are AWAY, not how long you stay.

For a standard residence permit (D7, D8, work, family), you keep it as long as you are not absent for:

more than 6 months in a row, or
more than 8 months in total over the full life of the permit.

Your first card lasts 2 years, and each renewal lasts 3 years, so that 8-month limit is counted over the whole 2 or 3 years, not per year.

It is not per year. The law measures it over the full validity period of the permit, not per calendar year.

In plain terms: on your first 2-year card, plan to spend at least about 8 months a year in Portugal, and never leave for more than 6 months at once. That keeps you safe.

If you have a real reason to be away longer (work, study, illness, family), that is allowed, as long as you can prove it. The cancellation is not automatic.

Do not confuse this with the "183 days" rule. Those 183 days decide whether you pay taxes in Portugal (tax residency). They have nothing to do with keeping your residence card. Two different systems.

Two special cases:

Permanent residence (after 5 years): much easier. You only risk losing it if you are away for 24 months in a row, or 30 months total over any 3 years.
Golden Visa: the lightest of all. Just 7 days in the first year, then 14 days every 2 years.

One important warning: keeping your card is easier than earning citizenship or permanent residence. Those need you to really live here. If you stay only the bare minimum, you can still hurt a future citizenship application.

Are Temporary Stay Visas valid for residence time?

No, the Temporary Stay Visa does not count as residence time.

What that means concretely:

Citizenship, under the 2026 nationality law, counts from the day the residence permit is issued. A temporary stay holder never gets that permit, so the clock never begins (and never qualified, even before the new law).
No AIMA card while on it. The visa itself is the authorization.
One-year ceiling. It covers stays over 90 days and up to a year, extendable inside Portugal via a 'prorrogação de permanência', but capped around that one-year wall.

What is a Temporary Stay Visa in Portugal?

A Temporary Stay Visa (Visto de Estada Temporária) is a Portuguese national visa for stays of more than 90 days but less than a year, for a specific purpose, and it does not make you a resident. It sits between a short Schengen visa and a full residence visa.

It authorizes a stay, not residence. You never get a residence permit or AIMA card from it, and time on it builds nothing toward permanent residence or citizenship.

Where it fits among Portuguese visas:

Short-stay (Schengen, Type C): up to 90 days.
Temporary Stay Visa: more than 90 days, up to about a year.
Residence visa (the D-series): for stays over a year, and it leads to a residence permit.

Who it's for: The Temporary Stay Visa covers a specific, time-limited reason to be in Portugal, including:

Study, exchange programs, or unpaid internships under a year
Professional training
Medical treatment, and accompanying a patient
Seasonal work
Research, teaching, or highly qualified activity for less than a year
Religious training or activity
Accompanying a family member who holds a temporary stay visa

How it works: It allows multiple entries and is valid for the length of the approved stay. Inside Portugal, the stay can be extended through a 'prorrogação de permanência' (extension of stay) at AIMA, but the total is capped at roughly one year. When it ends, it ends. There is no card and no renewal into residence.

How it differs from a residence visa, in one line: a residence visa is the door to becoming a resident, while the Temporary Stay Visa lets you stay a while for one defined purpose and then leave.

However, activity temporary stay holder can sometimes switch to a residence permit without leaving Portugal, for example by starting a qualifying job (art. 122 of the Immigration Act).

Residence then starts from the new permit. It is not backdated to the stay, so the stay time still counts for nothing. It can, though, be the doorway to a permit that does count.

Being an adult under Portuguese law

You have to be of age under Portuguese law, or legally emancipated, at the moment of the request.

Minors do not apply on this route in their own right. They have their own paths, including the one covered further down for the children of someone who naturalizes.

Great-grandparent route, five years instead of seven or ten

A great-grandchild of a Portuguese citizen by origin can naturalize after five years of legal residence in Portugal.

This is a residence-based route, so it lives as naturalization rather than with the pure descent routes, and it is the one of the shortest residence path in the system.

Five years of legal residence for a great-grandchild of a Portuguese national

Five years, in place of the seven or ten the ordinary route demands.

The law grants this shorter period to third-degree descendants in the direct line of an original Portuguese national, dispensing the ordinary residence-length rule for them.

This is the route a great-grandchild uses when no living grandparent or parent can carry a lighter descent claim. When a living relative does sit between the great-grandchild and the Portuguese great-grandparent, routing through them is usually better, and that cascade is explained in the guide to Portuguese citizenship through a grandparent.

It still requires the rest of the conditions

Five years shortens only the residence clock, and nothing else.

The great-grandchild still has to be an adult, show language and civics, hold a clean serious criminal record, and pose no security threat, exactly like any other naturalization applicant.

The three naturalization routes side by side

Route	Who it is for	Residence required	Language and civics	Nature
Ordinary, lusophone or EU	Citizens of Portuguese-speaking countries and EU member states	7 years	Yes (language proof exempt for lusophone nationals)	Naturalization
Ordinary, other nationals	Everyone without a lusophone or EU passport	10 years	Yes	Naturalization
Great-grandchild	Third-degree descendant of a Portuguese citizen by origin	5 years	Yes	Naturalization

All three share the same core conditions: adult, clean serious criminal record, no security threat, plus the civics knowledge and the solemn democratic-adherence declaration.

Only the residence length and the language exemption change between them.

An extra (rare) rule: Stateless applicants, four years

A stateless person, someone no country recognizes as a national, can naturalize after only four years of legal residence in Portugal. This is the official shortest residence route in the system, added by the 2026 law.

The four years is the only thing shortened. A stateless applicant still meets the same core conditions as anyone else: the language and culture, civics, the democratic-adherence declaration, a clean serious record, and no security threat.

For them, the procedure is free. Naturalization for stateless applicants carries no fee, unlike the 250 euros an ordinary applicant pays.

Portugal also works to prevent statelessness in the first place. A child born in Portugal who would otherwise have no nationality is Portuguese by origin, so nobody is born stateless on Portuguese soil. And a Portuguese nationality act is not annulled if doing so would leave the person stateless.

The catch is proof. Portugal does not yet have a formal procedure to officially recognize someone as stateless, and without that recognition the four-year route is hard to use in practice. The gap has already been raised before the courts, so it is a live issue rather than a settled one.

What are the requirements for Portuguese citizenship by naturalization?

The documents required are legal residence for the required period, proof of Portuguese language and culture, knowledge of civics, a solemn declaration of adherence to democratic principles, a clean serious criminal record, and no standing as a security threat.

This is the full battery the law sets for citizenship requirements via residency, and each part has its own evidence.

Legal residence for the required period

Documented, legal residence for seven years, ten years, or five for a great-grandchild.

You prove it with your residence permit and, ideally, an official residence-time certificate, covered in the documents section.

The official residence-time certificate is called 'Certidão de Contagem de Tempo de Residência' and is issued by AIMA.You can request via email, after completing the 'Modelo 7' form and attaching copies of your passport and residence permit. It's not essential and/or required for your Portuguese citizenship application, and AIMA will be consulted if you attach it or not, however some inidividuals choose to include it in their file.

Language proficiency

You have to show sufficient knowledge of Portuguese, and since 2026 also of its culture, history, and national symbols, by a test or a certificate.

For most applicants this begins with a language exam.

The CIPLE A2 test and the CAPLE certificate

The standard proof of language has been the CIPLE, the entry-level Portuguese certificate at A2 level, run by CAPLE.

You register with an identity document, sit the exam, and receive a certificate.

How long the certificate takes

The certificate is issued roughly 42 working days after the exam. So the test is a step to start early, well before you plan to file, rather than at the last minute.

Whether the certificate expires

CAPLE language certificates are for life, with no expiry date. Once you have it, you hold it, which is why taking the exam ahead of everything else costs you nothing.

The lusophone exemption

Nationals born in and holding the nationality of a Portuguese-speaking country do not have to present language proof.

A Brazilian applicant, for instance, is presumed to meet the language element and is exempt from submitting a certificate for it. The full list of exempt nationalities is in the questions section below.

The exemption covers the language itself. The culture, history, and symbols component that the 2026 law added is newer, and how it will be evidenced for everyone is one of the details still waiting on the regulation.

What the 2026 law added

The 2026 law broadened the requirement from language alone to language plus culture, history, and national symbols.

The exact instrument that will certify the broadened scope is pending. Confirm the current accepted proof at the IRN before you sit anything, and treat the language certificate as the part you can secure now.

Civics and the solemn declaration

You have to know the fundamental rights and duties of Portuguese nationality and how the State is organized, and to declare solemnly your adherence to the principles of a democratic State of law.

The declaration of adherence is a new formal step. It is made under commitment of honor, affirming respect for the Constitution, democratic values, and fundamental rights.

A clean criminal record and no security threat

No conviction to an effective prison sentence over three years for the grave crimes the law lists, and no standing as a threat to national security or defense.

The listed crimes include terrorism, violent and highly organized crime, and offenses against State security.

The three-year bar

The bar is a final conviction to more than three years of effective prison.

Before 2026 this threshold sat at five years, so the 2026 reform lowered the line at which a conviction blocks naturalization.

Which criminal records you need

Records from your country of nationality, from Portugal, and from every country where you have lived since around age sixteen.

The Portuguese record is usually pulled by the service itself when you authorize it on the application form. The foreign ones you gather and legalize.

Your documents must be valid on the day you submit, both still in date and within their accepted window.

Some documents have a short life. A criminal record certificate, for example, is usually valid for 90 days, so it has to be inside that 90-day window when you submit. Others are accepted based on when they were issued. An apostille, or an apostilled document, is generally considered valid when it was issued within the last 180 days, so it needs to fall inside that 180-day window at the moment of submission.

The rule of thumb: everything in your file should be current and inside its useful period on submission day.

Good news: in most cases, if everything is valid when you submit, it stays valid for the whole process, even if the document ages while your nationality is being analysed.

One heads-up: depending on how much time passes, the officer reviewing your case may ask for a fresh copy of a document. It does happen. But it is the exception, not the rule.

Where to take the CIPLE and how to learn Portuguese

You can sit the CIPLE at accredited centers in Portugal and abroad, and there are free courses that help you both pass it and settle in.

For the applicants who are not exempt, this is where the language requirement gets handled.

Where the CIPLE exam is held

The CIPLE is run by CAPLE, and the exam is held at accredited centers in Portugal and, through the Instituto Camões network, abroad.

In Portugal, universities and accredited language schools host the sittings across the country. Outside Portugal, Camões centers and partner institutions run them, so you can often take the exam without traveling to Portugal.

You register with an identity document, and CAPLE publishes the current center list and exam dates.

Check their website for where and when, since sittings are scheduled through the year.

Free and subsidized Portuguese courses

Portugal runs free and subsidized Portuguese courses for migrants under the 'Português Língua de Acolhimento' programme.

These courses are delivered through the employment and training institute, adult-learning 'Qualifica' centers, public schools, and municipal and migrant-support programmes.

They are aimed at helping migrants reach a working level of the language, and they can carry you toward the level the citizenship route asks for.

Your local migrant-support office, and the municipal network of integration centers, can point you to the nearest course. The offer changes by area, so the local center is the place to confirm what is running near you.

Why integration helps beyond the test

Beyond passing an exam, the language and the local ties are what make the years of residence livable.

The 2026 law leans harder on integration, adding culture, history, and symbols to the language element. Building real Portuguese, and real connections where you live, is no longer just a nice-to-have on this route, it is closer to the center of it.

What documents are needed for a citizenship application

Your application form, your birth certificate, proof of legal residence, criminal-record certificates, and your language certificate, all legalized and translated where they come from abroad.

Getting the file complete before you submit is the difference between a case that moves and one that stalls.

The application form

A completed 'requerimento' for naturalization, signed with your signature recognized.

The form is specific to the residence route, and every required field has to be filled, because an omission can sink the application on its own.

Your birth certificate

A full-copy birth certificate ('certidão de nascimento'), legalized and translated.

A foreign certificate needs an apostille and a certified Portuguese translation, covered in the legalization section next.

Proof of your legal residence

Your valid residence permit ('título de residência'), and you can put an official certificate of your residence time as an extra.

The residence-time certificate, requested from AIMA, is the cleanest way to prove when your clock started, and it heads off arguments about the count.

However, IRN will still contact AIMA to confirm your official residence time, even if you provide the official document.

Criminal-record certificates

Certificates from your country of nationality, your current country, and every country of prior residence since your mid-teens.

These carry a short validity, commonly around 90 days, so they are gathered late in the process rather than first.

Your language certificate

A CIPLE A2 certificate or an accepted equivalent, unless you are exempt as a lusophone national.

This is the part to secure early, given the certificate takes weeks to issue and never expires.

Submit a complete application

A missing required mention or a missing document can lead to summary rejection ('indeferimento liminar') or an 'exigência'.

The application warns of this directly. Filing an incomplete file does not buy you time, it risks losing the application outright, so the file goes in complete or not at all.

If you receive an 'exigência' request, this can delay your process even further.

What is an 'exigência' in the Portuguese citizenship process?

An 'exigência' is a formal request from the authority handling your nationality case, asking you to fix or complete something in your file, and it pauses your process until you answer it.

The word means "requirement" or "demand." In the citizenship process it's the official notice you get when the case officer reviews your application and finds a gap, an error, or missing proof.

What triggers one: During the analysis of your file, the officer flags something that blocks the case from moving forward. The usual causes:

A civil record not transcribed into the Portuguese registry, a classic in descent claims, where a marriage or birth has to be registered first.
A name that doesn't match across documents or across generations.
A criminal record certificate that expired before submission, or is missing its apostille or a certified translation.
Evidence the officer considers insufficient for the route, such as ties to the community for a grandchild claim, or the connection proof on a Sephardic file.
A document that's outdated, missing, incomplete, illegible, or the wrong version.

The effect that matters most: it suspends the clock. While an exigência is open, the analysis stops and your case sits still until you respond. That is why an unanswered exigência is the single most common reason a process stalls for months or ends up archived.

How you find out: Since the October 2024 nationality platform, exigências appear on the portal at nacionalidade.justica.gov.pt, with an email or SMS alert. If a lawyer or 'solicitador' filed for you, they are notified electronically, so they need to forward it to you quickly. In rare occasions, some people still report receiving notification via mail, if they are located in Portugal, as per their application form address.

The deadline is real: The notice sets a period to respond, and you should treat it as firm. Miss it and your case can be archived or refused. An extension is sometimes possible on a justified request, but do not count on it.

How to answer one well

Give exactly what is asked, complete, and consistent with what is already in your file. A fresh contradiction just creates a second problem.
Apostille first, then translate, any new foreign document.
Do not flood the file with unrelated papers.
Route the response through your representative if you have one.

One thing to hold onto: an exigência is not a rejection. It is a chance to fix the file, and a clean, fast response usually gets the case moving again. The ones that turn into refusals are the ones answered late, badly, or not at all.

Which documents come from where

Documents on this route come from three different places, and knowing which is which keeps you from ordering the wrong thing.

Document or step	Apostille or consular legalization	Certified translation	Signature recognition	Notarization
Foreign birth certificate	Yes	Yes, if not in Portuguese	No	No
Foreign criminal records	Yes	Yes, if not in Portuguese	No	No
The application form	No	No	Yes, in person	No
Power of attorney, if someone files for you	Yes, if signed abroad	Yes, if not in Portuguese	Yes	Yes
Portuguese documents (residence permit, Portuguese criminal record)	No	No	No	No

How to apply for Portuguese citizenship by naturalization

You can file in person at a nationality counter, by post to the central registry, or online through a lawyer, and where you file affects how cleanly your case starts.

This moment is where a lot of avoidable delay is created or avoided.

Where you can file

There are several places to submit a residence-based naturalization application. Each works, though they are not equal.

In person at a Balcão da Nacionalidade or a conservatória

In person at a 'Balcão da Nacionalidade' or a civil registry office ('conservatória do registo civil'). These are the counters set up to receive and, in many cases, handle nationality files.

File where there's a 'Balcão da Nacionalidade'. A naturalization case can be filed and decided at any 'Balcão da Nacionalidade', the nationality desk found at some 'conservatórias'. Not all offices have one, and filing at one that does keeps your case with a team that handles nationality directly. Confirm the desk exists in your chosen office before you send it.

At a CNAIM or a Loja do Cidadão counter

At an IRN counter inside the migrant-support centers ('CNAIM') in Lisbon and Porto, at the Espaço Registos in Areeiro in Lisbon, or at the 'Loja do Cidadão' in Odivelas.

These are common in-person options for people living in the two big cities.

By post to the Central Registry

By post, sending the complete file to any 'Balcão da Nacionalidade' registry office or to the 'Conservatória dos Registos Centrais'.

Postal filing works from anywhere, including from abroad, as long as the file is complete and the signature is already recognized.

Online through a lawyer or solicitador

Online, exclusively through a lawyer or a 'solicitador' registered with their professional body in Portugal. The online nationality service is not open to applicants directly, so the online route means hiring a professional to file for you.

The balcão question, and where residence files actually go

Choose your filing point deliberately, and check the current groups first, because where you hand the file in affects how cleanly it enters the system. This is the practical trap the expat communities talk about, and it has a specific twist for the residence route.

Check the Facebook groups before choosing where to file. Office speed comes down to staffing. Big 'conservatórias' have the volume and the people; small ones can run on a single 'conservador', so everything hangs on one person's availability and workload. Offices have stalled, and sometimes closed, when that person was out or left unreplaced. The community tracks which offices are actually moving, so check before you pick.

CRC, the biggest registry office in Lisbon is the only office that handles all of the Portuguese nationality routes option. Therefore the volume there is the heavier.

Some IRN offices direct applicants to file only via post. Others do accept in-person submissions, but may be subject to either a booking appointment via SIGAA or through queue ticket distrubtion.

Why filing at the wrong place gets your case forwarded

A registry office without a nationality desk does not process the file, it forwards it.

Applicants in the Facebook groups report that a case handed in at an office that does not deal with nationality gets sent on to a central operation, which adds handling time before anyone even opens it.

Where residence-naturalization files are actually handled

Residence-naturalization files under article 6 are instructed at the 'Balcão da Nacionalidade' where you file them, not centrally. The office that receives your case is the one that analyzes it, issues any exigência, and works it through to the decision.

Only two steps are central, and both are back-office. The grant is a decision of the Minister of Justice, delegable to the head of the IRN, and once granted, the naturalization is registered at the Conservatória dos Registos Centrais in Lisbon. Neither is where your case is handled.

A naturalization file stays at the local desk that received it. So where you file affects speed here too. The head of the IRN told Parliament that identical files move at different speeds depending on the office, with over 500,000 nationality cases spread across conservatórias around the country.

Choosing a lighter 'Balcão da Nacionalidade' is about both a clean, correctly-handled submission and a shorter queue.

Always check the Facebook groups before you choose

Before you pick a counter, check the current expat and nationality groups for where people are filing and what they report back.

Which offices accept and forward cleanly, which are slow to issue a process number, and which mishandle a file shifts over time, and the community tracks it in real time better than any static list. Confirming the current best place to file, before you file, is one of the highest-value things you can do on this route.

How you pay the fee

The naturalization fee is generally 250 euros, and you can settle it online in advance or in person when you file.

Confirm the current amount and accepted channels at the IRN, since these change.

Portuguese citizenship by naturalization fee

Around 250 euros for an adult applicant.

The naturalization process and its documents are exempt from stamp duty, so the fee is the main state cost. On top of it sit what you spend on certificates, apostilles, translations, and the language exam.

Paying online through the IRN portal, then filing

You can pay the fee online through the IRN payment service, keep the proof, and then submit the application by post or in person with the proof provided.

Paying ahead through the portal and then filing the complete file is a clean way to handle it, and it separates the payment from the queue at the counter.

Keep the payment reference and confirmation, because the file has to show the fee was settled.

Paying in person

The IRN accepts three ways to pay: online by Visa or Mastercard on the IRN platform, by a bank cheque, or by a vale postal (through CTT), the last two made out to 'IRN, IP'.

Pay online and you file with the code you receive (on an application form you'll receive via email). Pay by cheque or vale postal and you attach it to the documents you submit.

At a counter in Portugal, some offices will also take Multibanco at the desk, but that varies office by office and is not part of the IRN's listed methods, so the reliable routes are card online, or a cheque or vale postal with your file.

When I applied for Portuguese citizenship, I chose the office closest to where I lived, even though other locations were faster at the time. The idea was simple: if I or IRN needed anything, I could go there directly. I never needed to clarify anything, but this helped friends with more complex cases get guidance and complete their applications successfully. Where you apply depends on your priorities.

What is the process for naturalization, step by step

Confirm your eligibility and your clock, take the tests early, gather and legalize documents, pay and file, then track and respond.

The order matters, because a few of these steps take weeks on their own.

Step 1: confirm your eligibility and your clock

If you are in doubt, request an official residence-time certificate from AIMA to confirm exactly when your clock started.

This validates that your count runs from your permit issuance and that you have crossed seven, ten, or five years.

It removes the single most common source of a rejected count.

You must have completed the required residence period when you apply, not after, and not based on when your file will be reviewed.

At the time your application is submitted, all documents must be valid, and you must already meet IRN’s minimum legal residence time requirement, counted from your first issued residence permit. If you are missing by two days, you wait to submit.

Step 2: take the language and civic test early

Sit the CIPLE, or your civic and language requirement, before you open the file.

The certificate takes weeks to issue, and having it in hand means it is not the thing holding up your submission. Lusophone nationals skip the language exam under the exemption.

Step 3: gather, legalize, and translate your documents

Order your foreign certificates, apostille them, and have them translated.

Line up the birth certificate and the criminal records, remembering that the criminal records have a short validity, so time them to still be valid when the file goes in.

Step 4: pay and file

Settle the fee, sign the form with your signature recognized, and submit the complete file at a nationality counter or by post.

Choose where to file with the points above in mind.

Step 5: get your process password and track it

You receive a process password to follow the file on the IRN portal.

At an in-person filing it comes with your submission receipt. Through a lawyer it goes to the professional. Sometimes it arrives by email or letter days or weeks later, which is normal. If nothing comes after about 30 days, contact the office where you filed (though there are reports of people waiting for up to four months to receive it).

Step 6: respond to any document request fast

A document request ('exigência') suspends the analysis of your file until you answer it.

Watch the portal, and respond quickly and completely, because an unanswered request can leave a file stalled indefinitely. This is the single most common reason a process sits still.

What happens after approval

Once naturalization is granted and registered, you can apply for the Portuguese identity card ('Cartão de Cidadão') and passport.

The grant is made by decision of the Minister of Justice, registered at the central registry. From there you hold Portuguese citizenship and can obtain the documents that prove it.

What is the timeline for obtaining citizenship

Naturalization by residence is currently one of the slowest of the common routes, with the citizenship timeline updated to commonly quoted at three to four years from filing to grant in 2026.

There is no single number, and the legal deadlines are far shorter than the real ones, because of volume. At the end it all depende on your application period and fulfillment of residency requirements.

The real processing times

Practitioners report residence-based naturalization running roughly 36 to 48 months in 2026.

For comparison, children of a Portuguese parent are often quoted at under a year, grandchildren at well over a year, and marriage cases somewhere between. The IRN has reported analyzing hundreds of thousands of files at once, which is why the queues are long across the board.

The phases your file passes through

The IRN platform tracks a file through four phases. Here is what each one covers, and what applicants report about how long it lasts.

Phase	What is happening	Reported duration (variable, not official)
Submitted ('Submetido')	The file entered a service that handles nationality and was registered, given a process number, and checked at a surface level. It then waits in the queue to be distributed to a technician.	Days to weeks for a number, then a long queue wait. Often the longest single stretch. Right now, at the current situation, you can expect to stay a year or more in this phase.
In analysis ('Em análise')	A technician verifies the documents in detail, checks the legal requirements, confirms the certificates are authentic, and consults external bodies (the migration authority (AIMA), criminal police, criminal records, consulates). Document requests arise here.	Months to over two years. The wait on external consultations alone can run one to two years or more.
For decision ('Para decisão')	The analysis is finished and the file waits for the final decision to grant or refuse ('despacho').	Reported to sit for months.
Concluded ('Concluído')	The grant is registered, a Portuguese birth registration is created, and you can request the Cartão de Cidadão and passport. Or the file is refused and archived.	After a grant, the registration itself can take from a day to several months.

What the phases mean in practice

Most of the wait is spent between submission and decision, in the queue and then in analysis.

The external-consultation step inside analysis is the notorious one. Applicants report waiting many months, and in some cases well over a year, for the migration authority or the criminal-police check to come back.

There are no per-phase deadlines that the service reliably meets, so the durations above are reported experience, not official timings, and they vary widely by office and by how loaded the external bodies are.

If a file goes past 120 working days with no response, a court action to compel a decision is possible, which some applicants use when a case stalls.

What suspends the clock

A document request or a referral for assessment suspends the analysis until it is resolved.

The processing time you are quoted assumes a clean file. Every request you cause, and every incomplete answer, adds to the wait, which is why front-loading a complete, consistent file pays off directly in time.

That's when the 'exigência' comes.

The 2026 clock change

The residence count now starts at permit issuance, not at arrival or application.

Budget for this. Someone in the lusophone tier who once needed five years from an early date now needs seven from the day their permit was issued, which can push the eligible date out by several years.

The family angles, your children when you naturalize

When you naturalize, your minor children can acquire nationality through a declaration process, your adult children generally cannot, and a child born in Portugal during your residence may already have a claim of their own.

These three situations trip up almost every family, so they are worth separating cleanly.

Your minor children can acquire nationality too, by a declaration process

When a parent acquires Portuguese nationality, their children who are still minors can also acquire it.

This is a real and often-missed benefit of naturalizing. It is worth being precise about what it is, because it is lighter than naturalization but it is still a process.

It is a declaration, but a real process with documents and a fee

The route is a declaration, so it does not require the child to live in Portugal and it has no language test, but it is a formal process, filed with documents and registered.

It is not the same as the child running their own residence naturalization, and it is not an automatic add-on to your grant either. The legal representatives file a declaration for the child, and the service analyzes and registers it.

The 200-euro fee and the papers you file

The declaration carries a fee of 200 euros, and a specific set of documents.

The papers are the child's birth certificate, the parent's Portuguese birth certificate proving the acquisition, a document proving the child's foreign nationality, and the child's identity document. The signatures of the legal representatives are recognized in person.

Worth noting, the descent route for a child of a Portuguese by origin is free for a minor, as a naturalized person is not Portuguese by origin, this declaration for the child of a naturalized parent is the one that carries the 200-euro fee.

Extra steps for a child over sixteen

If the child is over sixteen, they also need criminal-record certificates and have to meet the criminal condition.

That means records from the country of nationality and birth, and from every country the child has lived in since sixteen, translated where they are in another language. The same bar applies as for an adult, no conviction to a sentence of three years or more for a serious crime.

Only children who were already minors when you acquired it

The route reaches only children who existed and were still minors at the date you acquired nationality, aka, your nationality was granted (not the time of submission).

A child born after you became Portuguese follows a different rule, and a child who was already an adult at that date is covered next. Incapable children are included even if they are no longer minors.

Your adult children cannot claim through your naturalization

An adult child of a parent who naturalizes has no automatic route through that parent.

This surprises people, and the reason is worth understanding, because it is not arbitrary.

Why the minor-children route covers only minors

The declaration route is written for minor or incapable children only. An adult, capable child falls outside it.

Why naturalization is not retroactive, unlike nationality of origin

Naturalization takes effect going forward, unlike nationality of origin, which relates back to birth.

A child of a parent who is Portuguese by origin can claim as a child, because that parent counts as Portuguese from birth, so the child was born to a Portuguese parent.

A child of a parent who naturalized was born before the parent was Portuguese, so that door does not open. The difference between origin and naturalization is exactly the difference between a route that reaches adult children and one that does not.

What an adult child can do instead

An adult child pursues their own route.

If they live in Portugal, they build their own residence and naturalize in their own right.

If there is a Portuguese-by-origin ancestor further up the line, such as a grandparent, a descent route may be open to them, which is covered in the guide to Portuguese citizenship through a grandparent.

What they cannot do is inherit the parent's naturalization.

A child born in Portugal while you are a resident, not yet a citizen

A child born in Portugal to foreign parents can be Portuguese by origin if a parent had five years of legal residence at the birth, whether or not that parent is a citizen yet.

So whether your Portugal-born child is Portuguese does not depend on your own citizenship, it depends on your residence.

If you already have five years of legal residence at the birth

With five years of legal residence at the moment of the birth, the child can be Portuguese by origin, by declaration.

Your own naturalization does not need to be finished. The child's claim stands on their birth in Portugal and your five years of residence, under the soil-based rule.

If you do not yet have five years

With less than five years of legal residence at the birth, the child is not Portuguese at birth.

The claim can open later, once a parent reaches five years of residence or the child completes a year of schooling in Portugal, through the naturalization route for minors born in the country.

So a child born early in your residence is not left without a path, the path simply comes a little later.

Can I get Portuguese citizenship by descent instead?

If you have a Portuguese parent, grandparent by origin, basically a qualifying ancestor, descent could be faster and, for a parent or grandparent, needs no residence at all.

It is always worth checking descent before committing years to the residence route.

For children born of a Portuguese parent, or a grandchild of a Portuguese grandparent, claims by bloodline from abroad, without living in Portugal. Only the great-grandchild route requires residence.

What changes are there in the citizenship law in 2026?

The 2026 new citizenship law change lengthened the residence requirement, changed how it is counted, lowered the criminal bar, added new integration steps, and closed two routes.

For the residence route specifically, the changes are substantial. Here they are side by side.

What changed	Before	Since 19-05-2026
Residence, lusophone and EU nationals	5 years	7 years
Residence, other nationals	5 years	10 years
How residence is counted	Some waiting time counted	Only from the residence-permit issuance
Criminal bar	Sentence of 5 years or more	Effective sentence over 3 years
Integration steps	Language	Language plus culture, history, symbols, civics, and a solemn democratic-adherence declaration
Loss of nationality	Narrow	Narrow
Parent naturalizing through a Portuguese child	Available	Closed
Sephardic descent	Available	Closed for new applications
Ancestry naturalization	Broader	Limited to great-grandchildren

Separately, the manifestation-of-interest path to residence ended in late 2025, which changes how many people become legal residents in the first place.

How the law passed

It was approved in Parliament on 01-04-2026, promulgated on 03-05-2026, published on 18-05-2026, and took effect on 19-05-2026.

The vote was 152 in favor, 64 against, and one abstention, making it the eleventh amendment to the Nationality Law and the broadest reform of access to Portuguese citizenship in over a decade.

Applications already pending when it took effect continue under the earlier rules, which the IRN applies by the date of submission.

Tips from the expat groups and forums

The people ahead of you in the queue have worked out what saves time, and their advice is consistent. A few points come up again and again.

Get your language certificate first, because it takes weeks and never expires.
Request the residence-time certificate from the migration authority to lock down your clock before you file.
Prepare every document apostilled and translated, and check names and dates for consistency across all of them, because a mismatch becomes a document request that costs months.
Confirm through the current Facebook groups where to file, and file where a nationality desk handles it cleanly.
Keep your process password and watch the portal, since a file sitting on the same phase for months is usually normal queue time, unless there is an unanswered document request.
Respond to any document request fast and completely, because it suspends your analysis until you do.
Budget honestly for three to four years, so the wait is a plan rather than a surprise.

Questions people ask most before applying

How many years do I need to live in Portugal to apply for citizenship?

Seven years for lusophone and EU nationals, ten for everyone else, and five for a great-grandchild of a Portuguese citizen.

The count runs from your residence-permit issuance, not from when you arrived.

Which nationalities do not need to take the Portuguese language test?

Nationals born in and holding the nationality of a country whose official language is Portuguese are exempt from the language proof.

These are Angola, Brazil, Cape Verde, Guinea-Bissau, Mozambique, São Tomé and Príncipe, and Timor-Leste.

Equatorial Guinea also has Portuguese as a co-official language, so its nationals fall in the same group, though the presumption can be set aside where knowledge of Portuguese is manifestly lacking. That caveat exists for every lusophone applicant in principle, and in practice it rarely troubles nationals of the countries where Portuguese is the everyday language.

The exemption covers the language element specifically.

How much does naturalization cost, and how do I pay?

Generally 250 euros for an adult, payable online through the IRN portal before you file, or in person by cheque, postal order, or Multibanco.

Confirm the current amount at the IRN, and keep your payment proof for the file.

Where should I file my application?

At a counter that handles nationality cleanly, and try to check the groups first.

How long does naturalization by residence take right now?

Commonly three to four years from filing to grant in 2026.

The wait is driven by volume, and a document request suspends the clock, so a complete, consistent file is the best way to keep the timeline as short as it can be.

If my child is born in Portugal before I get citizenship, are they Portuguese?

They can be, if a parent had five years of legal residence at the birth, regardless of whether that parent is a citizen yet.

With less than five years, the child is not Portuguese at birth, though a path can open later.

Can I keep my original nationality?

Yes, Portugal allows dual nationality, so you keep your existing citizenship.

Check only whether your other country restricts holding both.

What Portugal citizenship by naturalization really comes down to

Naturalization by residence is the route for people who live in Portugal, and since 2026 it asks for more time and counts that time more strictly.

Seven years for lusophone and EU nationals, ten for others, five for a great-grandchild, all counted from the day your residence permit was issued.

The requirements are a battery, so the file has to carry all of it: the residence, the language, the civics and the declaration, and a clean serious record.

The documents have to be apostilled, translated, and signed with your signature recognized, and the file has to go in complete, because an incomplete one risks summary rejection rather than a second chance.

Where you file matters for how fast your case starts and moves. Define your priorities, choose your counter, pay the fee online or at the counter, then track the process and answer any request fast.

Your minor children can acquire nationality with you through a declaration process, a real one with documents and a fee, and without living in Portugal.

Your adult children cannot ride on your naturalization, because it does not reach back the way nationality of origin does. And a child born in Portugal during your residence may already be Portuguese by origin, if you had five years of legal residence at the birth.

The whole route rests on one thing that comes before any of it: being a legal resident of Portugal, and staying one, for years.
