Portuguese Nationality Law: Court Challenges & Changes

In short
The path to Portuguese citizenship may have become more challenging, but with careful planning and proactive action, expats can still navigate this evolving landscape and achieve their goals.
LISBON — Portugal's appeal to expats has grown exponentially in recent years, drawn by its safety, quality of life, and the (previously) relatively accessible path to citizenship. However, a seismic shift is underway. The Portuguese Parliament has approved a new Nationality Law that dramatically alters the landscape for those seeking to call Portugal home, sparking both concern and confusion within the expat community.
But now, things are not moving forward. Let’s see why!
What's changing on Portugal’s nationality law?
The approved legislation represents a significant hardening of Portugal's citizenship policies, driven by the current center-right government (PSD/CDS), with crucial support from the right-wing Chega party. The key changes are:
- Extended Residency Requirements:General Rule: The minimum legal residency required to apply for citizenship doubles from 5 to 10 years for most non-EU/CPLP foreign residents.
- CPLP & EU Citizens: Citizens from Portuguese-speaking countries (like Brazil) and other EU nations now face a 7-year residency requirement, up from 5.
- Stricter Rules for Children Born in Portugal: To acquire Portuguese nationality at birth, children born in Portugal to foreign parents now require at least one parent to have 5 years of legal residency, a substantial increase from the previous 1-year rule.
- Potential Loss of Nationality: A separate amendment to the Penal Code introduces the possibility of revoking nationality for naturalized citizens convicted of serious crimes (4+ years imprisonment) within 10 years of acquiring citizenship, provided they hold another nationality.
These changes have sparked widespread debate, with some seeing them as necessary to safeguard national identity and ensure genuine integration, while others criticize them as discriminatory and a betrayal of Portugal's welcoming tradition.

PS takes it to court
The Socialist Party (PS), the main opposition force, has launched a legal challenge against the new law, requesting a "fiscalização preventiva" (preventative review) by the Constitutional Court (Tribunal Constitucional - TC). This means they are seeking to determine the law's constitutionality before it comes into effect.
The PS argues that the law violates core constitutional principles:
- Equality: The PS alleges unequal treatment of immigrants.
- Proportionality: Certain measures are seen as excessively harsh.
- Legitimate Expectations (Confiança): Retroactive changes undermine the legitimate expectations of those who planned their lives under the old rules. There’s potential for legal challenges from individuals whose residency clocks have been reset.
- Organic Law Requirement: The loss of nationality amendment should have been an organic law, requiring a higher level of parliamentary support.
What can the Tribunal Constitucional do?
The Constitutional Court wields significant power in this situation. It can:
- Declare the Law Constitutional: Upholding the law in its entirety, allowing it to proceed to presidential approval and subsequent implementation.
- Declare the Law Unconstitutional: Striking down the law completely, preventing it from taking effect. This would force the government to either abandon the reforms or draft a new, constitutionally sound version.
- Declare Parts of the Law Unconstitutional: Invalidating specific provisions while upholding others, leading to a partial implementation of the reforms.
- Delay Implementation: By taking time to review the law, the Court can effectively postpone its implementation, creating a period of uncertainty.
A rare moment in political history
Significantly, this is only the second time since the end of the Estado Novo dictatorship that a preventative review of a law has been requested before presidential approval.
The previous instance was in relation to abortion legislation, highlighting the gravity of the current situation. This historical context underscores the PS's belief that the new Nationality Law poses a serious threat to fundamental rights and freedoms.
What's valid NOW?
According to legal experts, the current Nationality Law remains in effect until the new legislation is formally approved and published. This means:
- 5-Year Residency (Generally) Still Applies: Individuals meeting the current 5-year residency requirement (or other existing criteria) should apply for citizenship immediately.
- One-Year Parent Residency for Children Born in Portugal Still Valid: The previous rule for children born in Portugal remains in force.
Seize the opportunity if you can
The clock is ticking. With the final wording of the law submitted to President Marcelo Rebelo de Sousa on November 5th, the window to apply under the existing, more lenient rules is rapidly closing.
- Presidential Review: The President has a limited time frame (up to 20 days) to review the law.
- Potential Constitutional Court Consultation: He may (and likely will, given the PS challenge) consult the Constitutional Court, potentially delaying the process but adding further uncertainty.
What to do right now:
- Assess Your Eligibility: Determine if you currently meet the requirements for citizenship under the existing law.
- Consult with Legal Professionals: Seek legal advice to understand your specific situation and the potential implications of the new law.
- Gather Documentation: Compile all necessary documents to support your application.
- Submit Your Application IMMEDIATELY: Don't delay. The opportunity to apply under the more favorable rules may disappear at any moment.

Stay informed and adapt
The situation surrounding Portugal's Nationality Law remains fluid. Expat communities must stay informed, seek expert advice, and adapt their plans accordingly.
- Monitor reputable Portuguese news sources for updates.
- Consult with immigration lawyers to understand your individual rights and options.
- Engage with expat communities for support and information sharing.
Key Takeaways
The path to Portuguese citizenship may have become more challenging, but with careful planning and proactive action, expats can still navigate this evolving landscape and achieve their goals.
