Requirements

If you want to find out whether you are or formerly have been a Finnish citizen, you can request the Finnish Immigration Service to determine your citizenship status.
  • Your identity has been reliably established
    • You can establish your identity by showing us reliable documents (such as your passport) or by giving us reliable information about at least your real name, date of birth, nationality and family ties. When we are determining your identity, we will also take into account any information you have given us earlier about your identity.
  • You did not lose your Finnish citizenship by the initiative of an authority
    • The Finnish Immigration Service may decide to revoke your citizenship
      • if you have given us false information on your previous citizenship application
      • if you got your citizenship based on your father’s citizenship, and his paternity has been annulled

These requirements must be met at the time you submit your declaration.
