🇵🇹 Portugal · Citizenship
Naturalization rules: required residence years, language and civics requirements, and each country's dual-citizenship policy.
Quick answer
Portugal grants nationality after 5 years of legal residence, with an A2 Portuguese-language requirement, and permits dual nationality. Portugal is generous with time counted and Sephardic/Portuguese-speaking ties. Note: reform proposals in 2025 sought to lengthen the residence period — always verify the current rule before relying on it.
Portugal reformed its nationality law in 2025: the residence requirement for naturalisation rose from five years to seven years for nationals of EU and Portuguese-speaking (CPLP) countries and ten years for other nationals. Applicants also need an A2 level of Portuguese and good standing. Portugal permits dual citizenship. Nationality is handled by the Institute of Registries and Notariat (under the Ministry of Justice).
- A 2025 reform raised naturalisation residence to seven years (EU/CPLP) or ten years (others) — up from five.
- You also need A2 Portuguese and good standing.
- Portugal permits dual citizenship; verify the current rule, as the reform is recent.
