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
