Becoming a Portuguese Citizen: The Residence Requirement

One of the most common questions people ask is whether living in Portugal will eventually let them become Portuguese citizens.

The short answer is that it often can — but under Lei Orgânica n.º 1/2026 (published in the Diário da República on 18 May 2026, in force since 19 May 2026), the residence period required for nationality is now longer than many older articles suggest. This guide explains the current residence requirement, when the qualifying period starts, and the points that most often cause confusion.

This page is a general explanation, not legal advice. Nationality decisions depend on your individual circumstances and the law in force at the time you apply.

1. How long must you live in Portugal?

*Legal Interpretation.* Under Lei Orgânica n.º 1/2026, the minimum period of legal residence now depends on your nationality. There are two main categories:

• EU citizens — 7 years
• Citizens of CPLP countries — 7 years
• All other nationalities — 10 years

CPLP (the Community of Portuguese Language Countries) includes:

• Brazil
• Angola
• Mozambique
• Cape Verde
• Guinea-Bissau
• São Tomé and Príncipe
• East Timor
• Equatorial Guinea

2. When does the clock start?

This is one of the biggest changes, and one of the easiest to misunderstand.

Old rule. The residence period could effectively begin from the residence application process, depending on the applicable legal regime and transitional rules.

New rule — *Legal Interpretation.* The qualifying period now starts strictly from the date your residence card is issued — not from the date you first applied or gave biometrics.

In practice, time spent waiting for AIMA appointments, for your application to be processed, or on general bureaucracy normally does not count towards nationality for new applications.

3. What still has NOT changed?

*Official Requirement.* You still need to satisfy the other naturalisation requirements, including:

• legal residence for the required period;
• knowledge of Portuguese (at least A2 level);
• no conviction for crimes carrying a sufficiently serious prison sentence under the law;
• compliance with the remaining legal requirements for naturalisation.

4. Transitional rules — which regime applies to you

*Official Requirement.* The dividing line is the date your nationality application is filed:

• Filed on or before 18 May 2026 — assessed under the previous 5-year residence regime.
• Filed on or after 19 May 2026 — the new 7- or 10-year periods apply. There is no transitional grace period for new applications.

So the decisive question is *when your application was (or will be) submitted*, not when you started living in Portugal.

5. Examples

Example A. A residence permit is issued in June 2026 and the applicant is Canadian. Under the 10-year rule, they would generally be eligible from June 2036.

Example B. A residence permit is issued in June 2026 and the applicant is Brazilian. As a CPLP citizen under the 7-year rule, they would generally be eligible from June 2033.

Example C. Someone filed a nationality application on 10 May 2026, before the new law. Because it was filed on or before 18 May 2026, it is assessed under the previous 5-year residence regime, not the new 7- or 10-year periods.

6. Permanent residence is different

An important point that many people miss: permanent residence and nationality are not the same thing.

You can still generally apply for permanent residence after 5 years of legal residence. The increase to 7 or 10 years applies to Portuguese nationality — not to permanent residence.

7. Other routes to nationality

The residence requirement is not the only route to nationality. Other routes still exist, including:

• marriage or de facto union with a Portuguese citizen, subject to the legal conditions for that route;
• descent from Portuguese parents or grandparents;
• other specific situations provided for in the Nationality Law.

These pathways follow different legal requirements and are not simply subject to the 7- or 10-year residence rule.
