Can you claim Finnish citizenship through a parent?
Citizen by birth (section 9) or declaration (section 26)
A child of a Finnish father is Finnish from birth if the parents were married; if not, a declaration does the same once paternity is established. Keep it past 22 by notifying a Finnish mission or holding a Finnish passport between 18 and 22.
What would settle itWhether your parents were married at your birth; if not, whether paternity has been legally established.
- A child of a Finnish father is Finnish at birth only if the father was married to the mother or the child was born in Finland with paternity established; a child born abroad to an unmarried Finnish father acquires citizenship by declaration once paternity is established. Finnish Nationality Act (kansalaisuuslaki 359/2003), official translation with amendments to 781/2022, Sections 9 and 26
- A Finnish citizen who also holds another citizenship keeps Finnish citizenship at 22 only with a sufficient connection to Finland: seven years’ residence in Finland or the Nordic countries before 22, or, between 18 and 22, a written notice of wishing to keep it, a Finnish passport or identity card, military service, or acquisition by application or declaration. Finnish Nationality Act (kansalaisuuslaki 359/2003), official translation with amendments to 781/2022, Section 34
- The Immigration Service confirms that citizenship lost at 22 for want of a connection can be regained by a former citizen’s declaration. Finnish Immigration Service: retaining Finnish citizenship at the age of 22
