- Notes
- As of 2026, Migri states that if you apply for Finnish citizenship on 1 Oct 2024 or thereafter, the general period of residence requirement is 8 years of legal residence in Finland. In some cases, a shorter period applies (commonly 5 years if you meet the language skills requirement; also 5 years with a Finnish spouse if cohabited 3 years; 2 years for Nordic citizens; 2 years for spouse of a Finnish diplomat; 5 years for stateless persons; and rare 3-year exceptions for special and weighty reasons). Applicants must be living in Finland and the residence must be legal throughout; gaps are not counted. You do not need permanent residence, but when applying you must have a valid continuous (A) or permanent (P) permit, and you must have lived in Finland with an A or P permit for at least 1 year before the application is decided. Time on a temporary (B) permit may be partly counted (typically half) before switching to an A permit, per Migri’s residence calculation rules.
- Dual citizenship
-
Dual citizenship: Allowed
Renunciation required: No
- Notes for dual citizenship
- Finland accepts multiple (dual) citizenship and does not require release from another citizenship when acquiring Finnish citizenship (accepted since 1 June 2003). Other countries may have their own rules about dual citizenship.
