Key figures — as of 2026-08-11: Naturalisation now requires 10 years of legal residence for most non-EU/CPLP applicants, 7 years for EU and CPLP nationals — up from 5 — under Lei Orgânica n.º 1/2026, in force since 19 May 2026; the residency clock starts on the date the first residence permit is issued, not the date of application; applications filed on or before 18 May 2026 are still assessed under the old 5-year rule.
The number that matters: zero credit for waiting
Portugal's citizenship reform grabbed headlines for doubling the naturalisation wait from five years to ten. Less noticed, but arguably more disruptive for people already living in Portugal, is a second change buried in the same law: time spent waiting for AIMA to issue a first residence card no longer counts towards that clock. Time spent waiting for an initial residence permit, often two to three years given current AIMA processing times, will not count toward the seven- or ten-year requirement for citizenship — the clock starts when the physical title is issued.
That single sentence is why immigration lawyers' inboxes have been full since May.
What changed, and when
On 3 May 2026, the President promulgated the law amending the Portuguese Nationality Law, raising the general residency requirement to ten years for non-CPLP, non-EU nationals and seven years for CPLP and EU nationals. The law came into force on 19 May 2026.
The start-date rule is the part causing the most confusion, largely because Portugal has flip-flopped on it. The new law resets the residency clock to the date AIMA issues the residence permit, reversing a 2024 amendment that had moved the start date to when applicants submitted their application. Anyone who read up on the rules in 2024 or 2025 learned one thing; anyone applying today needs to unlearn it.
The government has been explicit about the mechanics. Its own communiqué states: "este prazo começa a contar com a obtenção do título de residência" — the clock starts running from obtaining the residence title, not from filing for it.
Crucially, this isn't retroactive for people already in the system. If you filed your citizenship application with the IRN on or before 18 May 2026, the previous 5-year timeline still applies; if you file from 19 May onward, the new timeline applies even if you had already accrued five years of residence before that date.
Where the real confusion sits
For genuinely new arrivals, the IRN's reading of "issuance" isn't as simple as it sounds. One immigration-law source describes how caseworkers actually apply the rule: the IRN reads the date stamped on the first physical card or, where the first credential was digital-only, the issuance date recorded in AIMA's database — and for applicants who've held multiple consecutive permits, the clock starts on the very first card, not on each renewal.
There's also a live legal argument circulating among Golden Visa lawyers that hasn't been tested in court. Because Portuguese administrative law obliges the state to decide residence-permit applications within a set window, some practitioners argue delays beyond that shouldn't be held against the applicant. This is currently untested in practice: Portuguese administrative law requires the State to deliver a decision within 90 days, so it's arguable the citizenship clock should begin on day 91 from fee payment, regardless of when AIMA actually issues the card. Until a court or the IRN rules on that theory, nobody should bank on it.
President Seguro flagged the fairness issue himself when signing the law. He noted the revision "should also be based on greater consensus," specifically flagging that pending applications shouldn't be adversely affected and that timelines shouldn't be undermined by the state's own administrative delays.
GrowIN's analysis: the hidden extra years
Here's the calculation that matters for anyone planning around this. AIMA's average time to issue a first residence card has commonly run 12–24 months in recent years, and immigration commentary puts it at two to three years for some applicant categories. If an applicant waits, say, 24 months for their first card, the real elapsed time from first landing in Portugal to citizenship eligibility isn't 10 years — it's 12. For a non-EU applicant who also needs to pass A2 Portuguese and clear background checks, GrowIN Portugal Editorial's working estimate is that total realistic timelines for many 2026 applicants will land closer to 11–13 years door-to-passport, not the headline figure most people quote.
As GrowIN Portugal Editorial puts it: "The ten-year clock on paper and the real-world wait for a Portuguese passport are no longer the same number."
What to watch next
The Regulamento da Nacionalidade — secondary legislation clarifying evidentiary detail — is still being finalised, and the untested "90-day" argument could eventually reach the courts. Anyone holding a Golden Visa, D7, D8 or other residence permit should note the date their first card was physically issued, not their application date, and keep the paperwork to prove it. See our visas hub for the current routes and processing realities, and consult a licensed Portuguese immigration lawyer before assuming any timeline — AIMA processing speed remains the single biggest variable nobody can promise you.
