Key figures — as of 2026-08-26: Lei Orgânica 1/2026 has been in force since 19 May 2026 — naturalisation now requires proving "capacity to ensure one's own subsistence" (Art. 6(1)(i)) — the Ministério Público can move to annul newly granted citizenship within 2 years of registration — an effective prison sentence over 3 years for crimes such as terrorism, organised crime or aiding illegal immigration bars naturalisation and can ground that annulment.
A new requirement most applicants haven't heard of
Buried inside Portugal's headline-grabbing residency overhaul is a quieter change that catches many applicants off guard: naturalising foreigners must now demonstrate they can support themselves financially. The revised Article 6(1) of the Nationality Law lists "possuírem capacidade para assegurar a sua subsistência" — possessing the capacity to ensure one's own subsistence — as a formal requirement for naturalisation, alongside language, cultural knowledge and clean-record tests. Exactly how that capacity will be proven — bank statements, employment contracts, income thresholds — is not yet spelled out; the government has 90 days from publication of the law to update the Nationality Regulation approved under Decree-Law 237-A/2006, and that update is still pending.
The two-year sword hanging over new passports
The part of the reform most likely to alarm people who've already naturalised is the opposition mechanism. The Ministério Público has two years from the date citizenship is registered to formally oppose the acquisition, and the grounds are broad: a lack of effective ties to the national community assessed against the same material requirements used for naturalisation — including the new subsistence-capacity test and weighing any conviction for offences against national symbols. In practice, this means a Portuguese passport issued through naturalisation isn't fully beyond challenge the moment it's granted — prosecutors retain a two-year audit window to argue the person never really met the bar in the first place.
Separately, the law tightens the criminal threshold that blocks naturalisation outright. Anyone convicted to an effective prison sentence of three years or more for serious crimes — terrorism, organised crime, offences against state security, aiding illegal immigration, threats to national security, or being subject to UN or EU restrictive measures — cannot obtain nationality. That same conviction threshold feeds into the opposition process described above, giving the state a legal basis to challenge citizenship already granted if a disqualifying conviction surfaces within the two-year window.
How this sits alongside the residency extension
This clause lands on top of the much-discussed timeline change. Nationals of Portuguese-speaking countries and EU citizens now need 7 years of legal residence before applying, while everyone else faces 10 years — up from the old five-year rule. GrowIN's analysis: assuming the typical two-year residence permit renewal cycle used by AIMA, a non-CPLP applicant arriving today will need to complete roughly five renewal rounds before even filing for naturalisation, against two or three under the old five-year clock — nearly doubling the number of times an applicant must interact with AIMA, pay renewal fees and keep paperwork current before citizenship is even on the table.
Anyone who filed before the change is shielded from it: Article 7 of Lei Orgânica 1/2026 requires pending administrative procedures to be assessed under the previous wording. The law also closed a long-running route entirely — the special 2015 regime for descendants of Sephardic Jews was revoked for new applications, though cases already filed continue under the old rules.
What foreigners should actually do
GrowIN Portugal Editorial: "A Portuguese passport granted after May 2026 comes with a two-year probation period foreigners didn't have before."
For anyone mid-process or newly naturalised, the practical steps are the same as always — keep proof of income and employment on file, avoid gaps in legal residence, and don't assume a conviction abroad is irrelevant just because it predates the Portuguese application. Descent-based citizenship through parents or grandparents (Article 6's separate lineage route) is unaffected by any of this and carries no residency requirement, so families relying on ancestry rather than naturalisation face a different calculus entirely. Our visas hub tracks how the residency clock interacts with different permit types, which matters now that the naturalisation countdown starts from the date the permit is issued rather than arrival.
What to watch next: the pending Nationality Regulation update, which should clarify exactly how "capacity to ensure subsistence" gets documented in practice, and whether the Constitutional Court — which already struck down parts of an earlier draft in December 2025 — takes up further challenges to the opposition mechanism. Until that regulation lands, applicants are working from a law whose toughest new clause doesn't yet have a rulebook.
