Finnish nationality law details the conditions by which an individual is a national of Finland. The primary law governing these requirements is the Nationality Act, which came into force on 1 June 2003. Finland is a member state of the European Union (EU) and all Finnish nationals are EU citizens. They are entitled to free movement rights in EU and European Free Trade Association (EFTA) countries and may vote in elections to the European Parliament.
Any person born to a married Finnish parent is typically a Finnish national at birth, regardless of the place of birth. Children of unmarried couples in which only the father is Finnish must be legitimised for them to acquire Finnish nationality. Foreign nationals may naturalise after meeting a minimum residence requirement (usually eight years) and demonstrating proficiency in Finnish, Swedish, Finnish Sign Language, or Finland-Swedish Sign Language.
