What is AIMA Portugal?
AIMA is the government agency for integration, migration and asylum, created in 2023 to take over the administrative side of immigration from SEF.
It decides who can live in Portugal legally, issues the residence permits and cards that prove it, and handles asylum and integration alongside.
Here is what that means in practice, starting with its role and its services.
What is AIMA's role in immigration?
AIMA is the Portuguese government body responsible for the legal residency of non-EU, EEA, and Swiss nationals, and for EU citizens once they pass five years of legal residence.
If you fall into that group, AIMA is the immigration agency that controls whether, and how, you can stay in Portugal long-term.
The AIMA role in immigration is administrative, not police work. The AIMA responsibilities are issuing residence permits, deciding renewals, and processing family reunification so a legal resident can bring a spouse, children, or dependent parents.
The throughline: if you are not an EU, EEA, or Swiss citizen and intend to live in Portugal, you need a visa to enter, then a residence permit once you arrive, and your path runs through AIMA.
What services does AIMA provide?
The services AIMA provides fall into three areas: immigration administration, asylum and international protection, and migrant integration.
The first two are the administrative work SEF used to do; the third came from the old High Commission for Migration.
Most people only ever touch the first area, but knowing the full range of AIMA services tells you which door is even the right one.
Immigration administration
On the immigration side, AIMA services cover residence permits and the renewal of residence titles.
It also issues residence cards, extensions of stay, permanent residence certificates for EU citizens, residence cards for non-EU family members of EU citizens, and permits for UK nationals covered by the Brexit arrangements.
Two words come up constantly here, and it is worth pinning them down before the rest of the guide: the visa and the residence permit.
Which are the Portuguese visas?
The Portugal residence visa is what lets you enter Portugal to settle.
For non-EU nationals moving here it is usually a residence (D) visa issued by a consulate, such as the D7 (passive income or pensioners), D8 (remote workers and digital nomads), the work visas, the student visa, or the family route.
The visa is a temporary entry document; on its own it does not make you a resident. It is the ticket in, and AIMA is what you deal with once you land.
One thing many people miss: the consulate issues the visa, but AIMA has a binding say in the decision. A residence visa needs a mandatory prior opinion from AIMA ('parecer prévio'), which runs the migration-risk analysis on your application. So your file already passes through AIMA before you ever set foot in Portugal.
What is a Portugal residence permit?
The residence permit ('autorização de residência') is what makes you a legal resident, issued by AIMA after you arrive on your visa.
It comes as a physical residence card, usually valid two years and renewable, and is the document that carries your rights to live, work, and access services.
The whole point of the appointment and renewal steps below is getting and keeping this permit, and the application documents you prepare are the same ones AIMA checks at the appointment.
Asylum and international protection
AIMA is the competent body for asylum applications and international protection.
If you are in Portugal as an asylum seeker or a refugee, your file is decided here, under a separate legal track from the residence permits this guide focuses on.
Migrant integration
On the integration side, AIMA runs reception and inclusion programs, anti-discrimination work, and public services such as Portuguese-language resources and migrant support centers.
These integration services are separate from the permit services, but the same agency provides them.
Two supports are worth knowing, because hardly anyone uses them, and both now sit under AIMA.
What are the CNAIM and CLAIM offices?
- CNAIM ('Centros Nacionais de Apoio à Integração de Migrantes') are the large national one-stop centers that bring several public services under one roof: immigration, social security, health, and legal orientation, with phone translation in dozens of languages.
- CLAIM ('Centros Locais de Apoio à Integração de Migrantes') are the local version, smaller offices spread across municipalities that offer the same kind of orientation closer to where you live.
There is also the Migrant Support Line, on 808 257 257 or +351 21 810 61 91 (weekdays, roughly 9:00 to 19:00), which gives information in multiple languages at the cost of a local call.
All three help with orientation: which channel to use, how to fill a form, basic legal guidance. They do not decide your residence case, so use them to find the right door, not to unlock it.
What was SEF, and when was AIMA created?
AIMA was created by Decree-Law 41/2023 and began operating on 29 October 2023, replacing SEF ('Serviço de Estrangeiros e Fronteiras'), which had combined border enforcement with immigration administration.
You will still see AIMA services described in old SEF terms, so treat the two as the same lineage: same files, same offices in many cities, new name and a narrower job.
What does AIMA no longer do?
When SEF was dismantled its work was split up, so you do not turn up at the wrong place.
Border control went to the GNR and PSP (land and sea to the GNR, airports to the PSP), immigration crime and trafficking to the Polícia Judiciária, and passport issuance to the IRN.
AIMA kept the administrative and asylum work, not the policing.
What's AIMA's current status?
In short: the inherited backlog is mostly decided, renewals are online, and the friction has moved to appointments and card delivery.
The full picture is in the 2026 updates section near the end; here is the three-line version.
The backlog, in short
At its mid-2025 milestone AIMA's recovery task force reported more than 525,000 cases decided out of roughly one million inherited. 'Backlog cleared' refers to that historical queue.
Getting an appointment and receiving the physical card are still slow.
Card tracking
AIMA launched a tool, still in testing, that lets you follow your process from decision to card delivery, with a tracking code for the card itself.
As it's new, its statuses are not always in sync with the other portals.
NISS and renewals, in short
Renewals now run through the online Renewals Portal, and the NISS (social security number) has become a practical requirement to move a residence file forward.
Since mid-2026 AIMA and Segurança Social can assign a NISS on the spot in regularization cases.
