How Long Can I Leave Portugal on a Residence Permit? US and UK

If you hold a Portuguese residence permit, the Foreigners Law lets Portugal cancel it when you are away without a good reason for more than six consecutive months or eight months in total during a temporary permit, or more than 24 consecutive months or 30 months within three years on a permanent permit. These limits are in article 85 of Law 23/2007, apply to holders of residence permits under the Foreigners Law (the text does not mention nationality), and do not apply if you show professional, business, cultural or social activity abroad or get the absence justified by AIMA.

This guide sits among the residence routes to Portugal and sets out what article 85 says, how the long-term resident status counts absences differently, and what the law says about time abroad when you later want permanent residence or citizenship. We read the consolidated Foreigners Law on the Lisbon District Attorney General’s office legislation site, two AIMA pages and the Nationality Law on the Diário da República on 21 October 2026. The date of the latest information is 10 September 2026, when Law 62/2026 amended article 85 (see the last section). This is a summary of what the pages say, not legal advice; AIMA decides your case.

What limits does the Foreigners Law set on time abroad?

Article 85(2) of Law 23/2007 sets two pairs of limits. It begins “sem prejuízo da aplicação de disposições especiais” (without prejudice to special provisions) and says the permit may also be canceled when the holder, without acceptable reasons, is absent from the country:

Three words in the article decide how you read it. First, the verb is “pode”, may: the article gives the authority a power to cancel, not an automatic end of the permit. Second, the test is absence “sem razões atendíveis”, without acceptable reasons, so the reason for the absence matters. Third, “interpolados” means months that add up without being consecutive, so, in our illustration, ten weeks here and ten weeks there would add up.

The window differs between the two permits. For a temporary permit the eight months are counted across the permit’s whole validity, and our reading is that the law does not cut that period into years, since it says only “no período total de validade”. For a permanent permit the 30 months are counted within a period of three years. The article does not say how a day abroad is counted (a partial month, a day of departure or return). The page does not say, so do not assume a rule.

What if I need to stay away longer?

Three paragraphs of article 85 give you ways to stay protected:

• Ask first. Paragraph 3 says an absence beyond the limits “deve ser justificada” through a request to AIMA made before you leave Portugal or, in exceptional cases, after you leave.
• Show activity abroad. Paragraph 4 says the permit is not canceled for people who are absent for longer than the paragraph 2 limits when they show that during the absence they carried on a professional or business activity, or an activity of a cultural or social nature.
• Know what a cancellation looks like. Paragraph 5 says the cancellation is notified to you with the grounds for the decision and involves seizure of the permit. Paragraph 6 says the minister in charge of migration decides, with power to delegate to AIMA’s board. Paragraph 7 says you can challenge the decision in the administrative courts, with a non-suspensive effect (“efeito meramente devolutivo”).

The pages do not say which documents AIMA wants for a justification request or how long it takes. We found no AIMA page on the procedure, so ask AIMA before a long trip, in writing if you can. Our guide to renewing a residence permit covers the renewal side of the same article.

The limits also depend on the kind of permit. AIMA’s page on the permanent permit says holders of an investment residence permit who ask for the permanent version get a permanent investment permit that is excepted from article 85(2)(b) and paragraphs 3 and 4, with a reference to the cancellation for absences from the national territory in article 65-K of Regulatory Decree 84/2007. We did not read article 65-K; if you hold that permit, see our guide to investment residence and ask AIMA which absence rules apply to you.

Do absences count against permanent residence?

Article 80 of the Foreigners Law grants a permanent permit to foreigners who have held a temporary residence permit for at least five years and meet the other conditions. The text does not mention absences. It counts years as holder of the temporary permit, and AIMA’s page lists “titularidade de autorização de residência temporária há pelo menos 5 anos” among the documents. Whether an absence reduces those five years is not stated on the pages we read. Article 85 is the rule on absences, and it speaks of canceling a permit, not of reducing a period.

The EU long-term resident status is different and does count absences. It is a second status the law offers after five years, covered in AIMA’s page on article 125. Article 126(1)(a) asks for legal and uninterrupted residence in Portugal for the five years before the request. Article 126(4) then says absences do not interrupt that period and count in it if each is under six consecutive months and the total does not exceed ten months within the five years. Article 126(5) adds that absences due to a work posting, such as a cross-border service, also count. AIMA’s page asks for proof of “residência legal e ininterrupta” for those five years.

Once you hold the long-term resident status, article 131(1) lists when you lose it, among others:

• absence from the territory of the European Union for 12 consecutive months;
• absence from Portugal for six consecutive years.

Paragraphs 2 and 3 say longer absences justified by specific or exceptional reasons do not cause the loss, for example when the holder stayed in the country of origin to carry on a professional, business, cultural or social activity. Paragraph 4 says that after a loss under those two grounds you may regain the status by request if the conditions in article 126(1)(b) to (d) (resources, health insurance, accommodation) are met, with a decision due in three months. Paragraph 7 says the loss also means cancellation of the residence permit.

How does time abroad affect citizenship?

The consolidated Nationality Law (Law 37/81) asks in article 6(1)(b) for legal residence in Portuguese territory of at least ten years for nationals of countries other than Portuguese-speaking countries and EU member states, so for Americans and Britons. Article 15(1) defines legal residence as being in Portugal with your situation regularized under any title, visa or authorization of the foreigners regime. Article 15(3) adds up all periods of legal residence, “seguidos ou interpolados”, that fall within a maximum interval of 12 years for people of other countries. The nationality changes since May 2026 are covered in our guide to the 2026 nationality law changes, and the application steps in the citizenship by residence guide.

We searched the text of the consolidated Nationality Law and of the consolidated Nationality Regulation for a rule on absences or interruptions of the residence, and found none on the pages we read. The Regulation says legal residence is proven by a residence title, a certificate of the time of legal residence from AIMA, or other documents it lists. So the law text does not give a number of days abroad that is safe for a citizenship file, and it does not say whether a trip outside Portugal affects the count. If you plan to spend long periods abroad before applying, ask the registry how it treats them. That the pages are silent is our reading, not a rule.

The registry applies its own checks, so keep proof of your permits and ask before you file.

What about Britons who moved before 2021?

AIMA has a dedicated Brexit page for Britons. It says the Withdrawal Agreement entered into force on 1 February 2020 and the transition period ended on 31 December 2020. We have not read which rules apply to a Briton who moved before that date, so this guide does not say whether the limits above apply to them in the same way. Check AIMA’s Brexit page and our guide for Britons after Brexit before relying on the limits above.

We read AIMA’s Brexit page on 21 October 2026. It states no rule on absences. It gives a Brexit line, (+351) 214 236 709, open on working days from 8:00 to 14:00, and the address brexit@aima.gov.pt for questions on the Withdrawal Agreement.

How does a trip abroad relate to the Schengen rule?

The article 85 limits are about a permit holder’s absence from Portugal and are a separate matter from the Schengen 90/180 count. Our guide on the 90/180 rule explains that time on a permit or long-stay visa is outside that count. This guide does not read EU rules on how long a holder of a Portuguese permit may stay in another Schengen state.

What did we read, and what is the latest change?

Article 85 was last amended by Law 62/2026 of 10 September 2026, which the legislation site lists in the amendment notes under the article, and which says it enters into force the day after publication. The amending law prints in full only paragraph 5, on the notification and the seizure of the permit, and marks the other paragraphs of article 85 with “[…]”, unchanged. Article 131 was last amended by Decree-Law 41/2023 of 2 June 2023, and article 126 by Law 29/2012. The date of the latest information in this guide is 10 September 2026.

Official pages read on 21 October 2026: the consolidated Foreigners Law (Law 23/2007, articles 80, 85, 125, 126 and 131) and Law 62/2026 as published by the Lisbon District Attorney General’s office, AIMA’s pages on the permanent residence permit (article 80) and on the long-term resident status (article 125), and on the Diário da República the consolidated Nationality Law (Law 37/81) and the consolidated Nationality Regulation. We also read AIMA’s Brexit page. We did not read the Regulatory Decree 84/2007 article on investment permits (65-K).
