The language requirement for Portuguese citizenship

If you are applying for Portuguese nationality by naturalization, you must prove you know Portuguese. In practice the bar is level A2 of the Common European Framework, and the most common proof is the CIPLE certificate from CAPLE at the University of Lisbon. A2 means you can handle predictable everyday situations: shopping, directions, a simple conversation about yourself. It does not mean fluency.

What changed is everything around it. Since May 19, 2026, the amended nationality law also asks you to prove knowledge of Portuguese culture, history and national symbols, and of citizens’ rights and duties and how the state is organized. As of September 2026 the government has not yet published the rules for how that new knowledge is tested, so the language part is well mapped and the culture part is not.

Where the rules are written

Two documents matter, and they do different jobs.

• The Lei da Nacionalidade (Law 37/81, most recently amended and republished by Lei Orgânica n.º 1/2026, published May 18, 2026). This says what is required. Article 6 lists the requirements for naturalization.
• The Regulamento da Nacionalidade Portuguesa (annexed to Decreto-Lei n.º 237-A/2006, last republished by Decreto-Lei n.º 26/2022). This says how you prove it. Article 25 lists the certificates that count as proof of Portuguese.

The 2026 law gave the government 90 days from publication to update the Regulamento. As of this writing we have not found a published amendment in the Diário da República, and press coverage through August 2026 reported the same. Until one appears, article 25 as it stands is the list the registry works from.

What does the 2026 law actually require?

Article 6(1) of the amended law requires an adult applicant for naturalization to meet all of these at the moment of applying:

1. Be an adult under Portuguese law.
2. Have lived legally in Portugal for at least 7 years (nationals of Portuguese-speaking countries and EU citizens) or 10 years (everyone else). Before the reform it was five years for all.
3. Prove, by test or certificate, sufficient knowledge of the Portuguese language and culture, history and national symbols.
4. Know sufficiently the fundamental rights and duties of Portuguese citizenship and the political organization of the state.
5. Make a solemn declaration of adherence to the principles of the democratic rule of law.
6. Meet the criminal-record, security and sanctions conditions.
7. Be able to support themselves.

Notice that the law itself says “sufficient,” not “A2.” The level comes from the Regulamento and the certificates it accepts, and CAPLE states plainly that, under current Portuguese legislation, CIPLE (A2) is the minimum level for acquiring nationality.

Which certificates prove A2 Portuguese?

Article 25(2) of the Regulamento accepts any one of the following. You need one, not several.

If the registry (Conservatória dos Registos Centrais) doubts that a certificate is sufficient, it can ask the issuing authority to confirm it. A certificate that is not confirmed does not count, so keep the original and any transcript that states the level.

The CIPLE in brief

According to CAPLE, the CIPLE has three components: reading and writing (1 hour 15 minutes, 45% of the grade), listening (30 minutes, 30%) and speaking (about 15 minutes, done in pairs, 25%). You pass from 55%. International sessions run in May, July and November, with additional dates in Portugal. CAPLE listed the fee at €95 when we checked. We cover the exam task by task in our CIPLE A2 guide.

Who is exempt from the Portuguese language requirement?

Fewer people than is often claimed. Read these carefully.

• Nationals of Portuguese-speaking countries are presumed to know the language (article 6(10) of the amended law). The presumption falls away if a lack of Portuguese is manifest when they deal with the services. It covers only the language, not the new culture and civics knowledge.
• Children born in Portugal to foreign parents are naturalized under a separate rule (article 6(2)): one parent with five years of legal residence and the child enrolled in compulsory schooling. The language test is not among those conditions.
• Young children who have not finished the first cycle of basic education in a Portuguese-curriculum school can prove Portuguese with a declaration from the school or education center they attend (article 25(5)).
• People 60 or older who cannot read or write, and people with serious health problems or a certified disability, are not exempt. Article 25(6) says their test must be adapted to their ability to show knowledge of the language.
• People who have rendered relevant services to the Portuguese state can be excused both the residence period and the language-and-culture requirement (article 6(9)). This is a discretionary government decision, not a route you apply into.

Does marriage to a Portuguese citizen require the language test?

Nationality through marriage or a recognized de facto union of more than three years is acquired by declaration (article 3), not naturalization, so article 6’s list does not apply directly. But the reform changed the ground on which the public prosecutor can oppose the acquisition: a lack of effective ties to the Portuguese community, now assessed against the same parameters as article 6, which include language and culture (article 9(1)(a)).

There is no opposition on those grounds when the marriage or union has lasted more than six years, or when the couple have children together who are Portuguese (article 9(2)). For shorter marriages, having an A2 certificate in the file is the simplest way to show the tie. How the registry will apply the new parameters in practice is one of the things the updated Regulamento should settle.

What is the new culture and civics test?

The 2026 law requires proof, by test or certificate, of knowledge of Portuguese culture, history and national symbols, plus knowledge of citizens’ fundamental rights and duties and the political organization of the state. That is the full extent of what the law says.

As of September 2026, these questions have no official answer:

• Whether it is written, oral or online, and who sets and marks it.
• What the pass mark is, what it costs, and where it is held.
• Whether any existing certificate, such as a PLA course, will count toward it.
• Which exemptions, if any, will apply.

The Ministry of Justice’s own announcement of the new rules lists the requirement without describing the test. Until the Regulamento is amended, treat any site that tells you the format with confidence as guessing. Check the Diário da República and the Ministry of Justice for the decree.

What you can do now is learn the material the law names. The words you will meet are the ordinary ones: a Assembleia da República, o Presidente da República, a Constituição, a bandeira, o hino nacional, o 25 de Abril, os direitos e deveres. Learning them in Portuguese serves both requirements at once.

How long does it take to reach A2?

No official body publishes a figure, and it depends heavily on what you already speak. What we can say is structural: with the residence period now 7 or 10 years for new applicants, almost nobody is short of time. The risk is leaving it to the last year and then waiting for an exam session. Sitting the CIPLE early also has a side benefit: the certificate is in your file whenever you apply. CAPLE’s FAQ does not state an expiry for it.

A practical order that works for most expats:

1. Get to a solid A1 in European Portuguese. Learn the Portugal forms from the start (estou a trabalhar, o pequeno-almoço, o autocarro) so there is nothing to unlearn. Our guide to learning European Portuguese sets out a path.
2. Check whether a PLA course runs near you through IEFP, a public school or a Centro Qualifica; the certificate itself is accepted proof.
3. In the three months before your exam session, practice in the CIPLE’s format: timed reading, short forms and messages, listening to recorded announcements, and a paired conversation.
4. Add the culture and civics material as soon as the new test’s rules are published.

Families have one extra thing to plan: each adult needs their own proof, while children follow the school-based rules above. Our guide for expat families covers learning together.

Checklist

• Work out your residence clock: 7 or 10 years, or the old rules if you applied before May 19, 2026.
• Pick one proof from the table above. For most adults that is the CIPLE or a PLA certificate at A2.
• Keep the original certificate and anything that states the CEFR level.
• Watch for the amended Regulamento, which will define the culture and civics test.
• If your case is unusual, ask a registry office or a lawyer before you file.
