A former Finnish citizen may acquire Finnish citizenship through the declaration process.
A Finnish citizen who also holds the citizenship of a foreign State may still lose Finnish citizenship when reaching the age of 22 years.
Former Finnish citizens can apply to regain citizenship through the declaration process. The declaration process is permanent. There are no deadlines for submitting a declaration. There is thus no rush to submit a citizenship declaration. A person living abroad can initiate the declaration process also at any police department in connection with a visit to Finland.
NOTE! Citizenship declarations may not be sent by post. They must be submitted in person.
As from 1 September 2011, the underage children of a former Finnish citizen may also be co-applicants and thus may acquire Finnish citizenship through the application submitted by the main applicant.
A minor may also be in the position of an applicant alone, but then it is required that he or she is a former Finnish citizen.
Adult children may acquire Finnish citizenship only in the event that they themselves have had Finnish citizenship at some time.
A citizenship declaration is submitted primarily at a police department when visiting Finland.
A citizenship declaration can also be submitted at a Finnish diplomatic mission or, exceptionally, an honorary consulate.
In the event of handling matters with an honorary consul, remember to make an appointment in advance. In general, honorary consuls are not available regularly. We also recommend making an appointment in advance when handling matters at a diplomatic mission.
A fee is charged for a citizenship declaration. Abroad, the fee must be paid in advance into the diplomatic mission’s account or at the diplomatic mission. The fee cannot be paid to an honorary consul. Customers are responsible for the bank fees and costs incurred in procuring documents.
Contact the diplomatic mission with regard to payment.

Application fees: the Finnish Immigration Service
However, no fee is collected from war veterans or war children.
For the declaration process, the customer must have the documents required by the Finnish Immigration Service in legalised form and obtaining the documents may take time. Incomplete applications can be supplemented afterwards by submitting the documents to a diplomatic mission or the Finnish Immigration Service, but not an honorary consulate.
If the co-applicant is an underage child, he or she must also be present in person. It must be possible to prove identity with a personal passport or, if there isn’t one, with an identity document issued by a public authority.
A child acquires Finnish citizenship at birth if:
A declaration on the birth of a Finnish citizen abroad can be submitted either to a diplomatic mission of Finland or directly to the register office of your domicile.
Remember that you may lose your Finnish citizenship when reaching the age of 22 years.
In accordance with the Nationality Act, a multinational may still lose Finnish citizenship when reaching the age of 22 years if he or she has not had a sufficient connection with Finland. The requirements have changed slightly. A sufficient connection can now be demonstrated merely by applying for a Finnish passport at 18–21 years of age.
The connection with Finland is also sufficient if:
It is essential that the child’s paternity has been established. Establishment of paternity done abroad must be valid in Finland.
A child automatically acquires Finnish citizenship through the marriage of his or her parents as of the date when the marriage was contracted, if the child’s father is a Finnish citizen. If the child’s father is not married with the child’s mother when the child is born, the child acquires Finnish citizenship by declaration. The declaration process, however, only applies to children born on or after 1 June 2003.
A fee is charged for a citizenship declaration.
If you are unsure whether you are, or your child is, a Finnish citizen, you may request that the citizenship status be defined either directly from the Finnish Immigration Service or through a Finnish diplomatic mission. A fee is charged for definition of citizenship.
A Finnish diplomatic mission may request definition in connection with a passport application when information on the person’s citizenship in the population register system may be incorrect or is not up to date.
You may apply to be released from Finnish citizenship if you are also the citizen of another State or are about to become the citizen of another State.
A fee is charged for the application.
Application forms can be downloaded from the website of the Finnish Immigration Service. The forms contain information on their completion and the appendices necessary.
