Citizenship declaration

The Finnish Immigration Service may grant Finnish citizenship on declaration or on application. For an applicant, the declaration procedure is a faster and more inexpensive way to become a citizen. Finnish citizenship may be obtained by declaration by:

• a child born abroad and out of wedlock to a Finnish man or a Finnish non-birth mother
• an adopted child between 12 and 17 years of age
• a former Finnish citizen
• a Nordic citizen
• a young person between 18 and 22 years of age who has lived in Finland long enough
