You can apply for Finnish citizenship if you are over 18, have had permanent residence in Finland for a sufficient amount of time and still reside in Finland. Proof of identity is required. You must also be able to present a plan of how you and your family intend to support yourselves. You also need to have knowledge of the Finnish or Swedish language, or alternatively Swedish or Finnish Sign Language.
