Portugal's 2026 citizenship test: the complete guide

Since 19 May 2026, applying for Portuguese nationality through naturalisation means proving you know the language, culture, history and national symbols — plus fundamental rights, duties and how the Portuguese State is organised. That's Organic Law 1/2026, which amended the Nationality Law. One piece is missing: the regulation defining what the test will actually look like. Here's what's certain, what isn't, and what you can do in the meantime.

What the law actually requires

The amended article 6 of the Nationality Law adds two requirements. Point c) asks for proof, “through test or certificate”, of sufficient knowledge of the Portuguese language and culture, history and national symbols. Point d) adds fundamental rights and duties and the political organisation of the State — without saying, yet, how that gets proven.

In practice, five themes: history of Portugal, culture and society, national symbols, rights and duties, organisation of the State. Our free 20-question mock exam is built on exactly these five.

Who has to take it

• Naturalisation by residence — the main route. Now 7 years of legal residence for CPLP and EU citizens, 10 for everyone else.
• Brazilians and CPLP citizens — exempt from the language component only, not the rest. Details in our article on Brazilians and the test.
• Grandchildren of Portuguese citizens — the statute explicitly applies the same knowledge requirements to them.
• Great-grandchildren — their own route waives the residence period, but not the knowledge requirement.

Do not confuse “not sitting the test” with “being exempt”. The statute grants exactly one express dispensation, and it is narrow: article 6(9) lets the Government waive points b) and c) — residence, language and culture — for people who have rendered, or are called to render, relevant services to the Portuguese State. Note that point d), fundamental rights and duties and the organisation of the State, is not covered by that waiver. Everything else is a route that never passes through the naturalisation article in the first place: marriage, união de facto, adoption, minor children of someone being naturalised, minors born in Portugal. There the requirement does not apply because it is not part of that process, not because anyone was excused from it. We walk through each route in our article on exemptions and dispensations.

Two claims are repeated everywhere that the law does not support. Studying in Portugal exempts nobody: what point c) allows is proof “through test or certificate”, and the Regulamento da Nacionalidade accepts a school certificate from an establishment in a Portuguese-speaking country — an alternative way of proving it, not an exemption, and it covers the language, not point d). And the serious-illness provision governs the language test, and has not been extended to the new knowledge test. One genuine exception is timing: applications filed before 19 May 2026 follow the old rules, with no test (article 7(2) of Organic Law 1/2026).

What nobody knows yet

Almost everything that matters for exam day — and now with no deadline in sight.

1. 18 May 2026

   Organic Law 1/2026 is published. The 90 days given to the Government to regulate run from this date.
2. 19 May 2026

   The law takes effect. From here on, naturalisation requires the knowledge requirement to be met.
3. 16 August 2026

   The 90 days run out. Nothing was published — and the statute attaches no consequence to missing the deadline.
4. Today

   No regulation and no new date. Nothing lapsed, and no fallback rule took effect.

There is still no official format, question count, pass mark, fee or confirmed administering body. Anyone claiming otherwise is guessing.

There are reasonable clues: the language test Portugal already runs, and the equivalent civic tests abroad — all of them multiple-choice.

Something in that family is the sensible expectation — and it's how we structured our mock exams, with a guaranteed update the day the regulation lands.

How to prepare now

The facts won't change with the regulation. Portuguese history, the Constitution, the symbols, how the organs of sovereignty work — the material is the material. The regulation will fix the format, not the content. Studying now is time banked, not time wasted.
