- Notes
- As of 2026, the amended nationality law sets the legal-residence requirement at 10 years for most applicants, with a reduced 7-year requirement for (a) nationals of Portuguese-language official countries (CPLP) and (b) EU Member State citizens. Residence must be legal (holding a valid residence right/title). Naturalisation also requires proof of knowledge of Portuguese language and (per the amended text) Portuguese culture/history/symbols, plus criminal-record/public-security type conditions. Some Justice Portal pages may still show the older 5-year wording; use the amended law text for the current residence period.
- Dual citizenship
-
Dual citizenship: Allowed
Renunciation required: NoSpecial cases: Portugal generally allows dual/multiple nationality. Note: other countries may require renunciation under their own laws (outside Portugal’s control).
- Notes for dual citizenship
- Justice Portal: Portuguese law allows a Portuguese person to have other nationalities; it is not necessary to give up another nationality to acquire Portuguese nationality, but other countries may impose their own rules.
Qualifying residence permits
ARI / Investment residence permit (Autorização de Residência para Atividade de Investimento)
An ARI is a residence authorization (legal residence) and therefore qualifies for the legal-residence clock.
Counts
EU citizen residence right / CRUE pathway (AIMA – nationals of EU and family members)
EU citizens residing in Portugal under EU free-movement rules have a legal residence right; the amended nationality law sets a reduced 7-year term for EU citizens.
Counts
Non-qualifying example: short-stay visa / tourist stay without residence authorization
Short-stay presence without a residence authorization is not “legal residence” for the naturalisation residence clock.
Doesn’t count
Permanent residence permit (Autorização de residência permanente)
Permanent residence is not required for naturalisation, but if held it is a qualifying legal residence status.
Counts
Temporary residence permit (Autorização de residência temporária – e.g., work, study, family)
Legal residence on a valid temporary residence permit counts as legal residence time for the nationality clock (naturalisation is based on legal residence, not necessarily permanent residence).
