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 old law contained a specific provision (Article 15.º(4) of the Nationality Law) under which the residence period could count from the date you applied for your residence permit. That mattered enormously, because it meant AIMA's own delays didn't cost you nationality time.

What actually changed — Official Requirement. The new law repealed that provision. It did not replace it with a new counting rule; it simply deleted the one that let you count from the application date. What survives is the general rule (Article 15.º(1)): legal residence is time spent here holding one of the titles, visas or authorisations provided for in the immigration regime.

What that means in practice — Legal Interpretation. The waiting itself no longer counts. Time spent queuing for an AIMA appointment, or waiting for a decision, before you hold anything, no longer counts for nationality purposes. That is the substance of the change, and it is why administrative delay now directly postpones your earliest nationality date.

Be careful with the version of this you'll read elsewhere. Many guides — including, until this revision, ours — state that the clock now starts "from the issuance of your residence card". The law does not say that. No sentence in it names the card. And the text that remains counts time under "titles, visas or authorisations", which on its face includes the period you hold a residence visa, before any card exists. Whether the counting starts at the visa or at the card is therefore a real open question that the statute does not settle, and we are not going to invent an answer to it. If your earliest nationality date turns on those few months, that is a question for a lawyer, and worth paying for.

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.
