Key figures — as of 2026-09-10: Naturalisation residency requirement rises from 5 years to 10 years for most non-EU/non-CPLP foreigners — 7 years for EU and Portuguese-speaking-country (CPLP) nationals — under Lei Orgânica n.º 1/2026, in force since 19 May 2026 — the residency clock now starts on the date the residence card is issued, not the application date, and applicants need A2-level Portuguese plus a new civics test.
A five-year wait just became a decade-long one
Portugal's overhauled Nationality Law has moved from parliamentary debate to daily practice at IRN registry offices, and the headline number for foreigners is stark: most non-EU applicants now need ten years of legal residence before they can even apply for a Portuguese passport, up from five. The new law increases the minimum legal residence periods required for the acquisition of Portuguese nationality through naturalisation from five years under the previous regime to seven years for citizens of EU member states and Community of Portuguese Language Countries member states, and 10 years for citizens of other states.
The change was signed off by President Seguro on 3 May 2026 and approved by parliament on 1 April, published in the Official Gazette as Organic Law No. 1/2026 on 18 May and entered into force the following day. For Britons, Americans, Canadians, Australians and most other non-EU, non-CPLP nationals settling in Portugal, ten years is now the benchmark, not five.
Why the "start date" change matters as much as the number itself
The bigger practical shock for many applicants isn't the headline figure — it's how the clock now starts. Under the previous rules, residency time could count from the date a residence permit application was submitted. Under the new rules, residency only begins counting from the date the residence permit is officially issued. Given that delays at AIMA mean many residents wait 18 to 24 months for their first residence card, this single procedural tweak can add nearly two extra years onto an already-longer timeline — years spent in Portugal that simply won't count toward citizenship.
GrowIN Portugal's own read on the numbers: a non-EU, non-CPLP applicant who arrives today and waits the upper end of that 18–24 month AIMA backlog before their first card is issued could realistically be looking at roughly 12 years from arrival to eligibility — a jump of well over 140% on the old five-year benchmark. That's not a rounding error; it's a fundamentally different immigration proposition for anyone weighing a long-term move to Portugal versus, say, Spain or Italy.
What else is now required
Beyond the years, applicants face a genuinely tougher integration test. Under the reformed law, naturalisation requires proficiency in the Portuguese language (A2 level minimum), knowledge of Portuguese culture, civic rights and duties, and the country's political organisation through a formal assessment, a solemn declaration of adherence to democratic principles, alongside a clean criminal record — applicants with sentences of three years or more are ineligible. None of this is a paperwork formality; it's assessed formally, and consular or IRN staff can request further verification if a candidate's spoken Portuguese looks shaky on the day.
There is a firm cut-off for who falls under which regime. No transitional or grandfathering rules apply, though applications already pending on 19 May 2026 continue under the previous rules. Miss that date without a filed application, and the new 7- or 10-year clock applies regardless of how long you've already lived in Portugal.
One route the reform left untouched: descent. Applicants tracing citizenship through a Portuguese grandparent under the Article 6 lineage provision still face no residency requirement, only proof of lineage, A2 Portuguese, and demonstrable ties to the Portuguese community — a pathway that remains considerably faster than naturalisation for those who qualify. Foreigners weighing options should compare routes on our visas hub before committing to a residency-based strategy.
"A five-year promise has quietly become a decade-long commitment, and the extra AIMA processing time is the part nobody budgeted for," says GrowIN Portugal Editorial.
What to watch next
The government has a 90-day window from the law's entry into force to publish the updated Regulamento da Nacionalidade — the detailed implementing rules that will clarify grey areas, including whether residency time accrued by Golden Visa holders before 19 May 2026 who haven't yet filed will count toward the new thresholds. AIMA has not yet issued formal guidance on that point. Anyone currently mid-residency and eyeing eventual naturalisation should get professional legal advice now, since filing timing — not just years lived in the country — is what will determine which set of rules applies to their case.
