What changed
Portugal’s overhauled Nationality Law is now in force, and it does far more than push back the naturalisation clock. Alongside the widely reported jump in residency requirements, foreigners applying to become Portuguese citizens must now clear two new hurdles that didn’t exist before: a civic and historical knowledge test, and a signed declaration committing them to the principles of democratic rule of law.
The legislation — Lei Orgânica n.º 1/2026 — was published in the Diário da República on 18 May 2026 and took effect the following day. Under the amended Article 6, applicants must, among other conditions, “sufficiently know the fundamental rights and duties inherent to Portuguese nationality and the political organisation of the Portuguese State” and formally “declare solemnly their adherence to the fundamental principles of the democratic rule of law state.”
This isn’t a minor administrative add-on. It marks a shift in what “earning” Portuguese citizenship is meant to demonstrate — not just time spent in the country, but a working knowledge of how it governs itself.
The substance of the test
According to legal analysis of the reform, the new integration requirement covers proof of knowledge of the Portuguese language, culture, history and national symbols, either through examinations or official certification. Applicants will also need to demonstrate understanding of the country’s political system and the rights and duties associated with Portuguese nationality.
The democracy pledge itself has drawn comparisons abroad. Portugal Resident notes the law introduces a “solemn declaration of adherence to the principles of the democratic rule of law”, described by some as similar to the model used in the United States.
What isn’t yet settled is the practical mechanics — whether this becomes a written exam, an interview, an online module, or acceptance of an existing certificate. As Portugal Resident puts it, several of these requirements still need detailed regulation before they can be fully implemented. The government has 90 days from the law’s publication to issue an updated Regulamento da Nacionalidade spelling out the format, and until that regulation lands, conservatórias and the IRN are working with limited practical guidance.
Sitting alongside a longer residency clock
The civic test and declaration are layered on top of — not instead of — the headline change: naturalisation now requires 7 years of legal residence for EU and CPLP (Portuguese-speaking country) nationals, up from 5, and 10 years for everyone else. The residency clock now starts from the date the first residence permit is issued, not the application date.
Applications filed on or before 18 May 2026 are shielded from these changes. The law’s transitional rule states that the previous five-year regime continues to apply to administrative procedures already pending when the new law entered into force. Anyone who hadn’t yet filed by that date is now under the new framework, with no grandfathering for people who had simply been accumulating residency time. Full details on the residency route sit in our visas hub, which covers how the timeline change interacts with D7, D8 and Golden Visa holders.
The security bar has also tightened. Naturalisation is barred for applicants with an effective prison sentence over three years for offences including terrorism, violent or highly organised crime, crimes against state security, or facilitating illegal immigration, and the law adds a new condition requiring applicants not be subject to UN or EU restrictive measures.
What this means in practice
For most foreigners building a life in Portugal, the test and declaration are unlikely to be the hardest part of the process — the extended residency requirement is the bigger practical obstacle. But they add a genuine preparation step that didn’t previously exist: alongside the A2 Portuguese language requirement already in place, applicants will need to study Portuguese civics and history specifically for this purpose, not just pick up conversational language skills.
Until the implementing regulation is published, anyone close to filing should treat the civic and language elements as a moving target. Confirm current requirements directly with the IRN (irn.justica.gov.pt) and AIMA before assuming any particular study guide or online course satisfies the legal standard — providers marketing “official” test prep at this stage are getting ahead of the actual regulation.
What to watch next
The 90-day deadline for the Regulamento da Nacionalidade puts the government on the clock through roughly mid-August 2026 to define exactly how the civic knowledge assessment will be administered. A separate companion decree that would have allowed loss of nationality as a criminal penalty remains under constitutional review and was not part of the version that entered into force. Foreigners with applications in progress, or close to meeting the old thresholds, should get case-specific advice from a Portuguese immigration lawyer rather than relying on forum chatter — the gap between what the law says and how it will actually be applied is still being written.
