Losing Finnish citizenship
If you have become a Finnish citizen by application or by declaration and given false or misleading information at that time, you may later lose your Finnish citizenship. You may also lose your Finnish citizenship if you have become a citizen on the basis of your father’s citizenship or your non-birth mother’s citizenship but his paternity or her maternity is later annulled.
You will automatically lose your Finnish citizenship when you turn 22 if you are a citizen another state and you have not had a sufficient connection to Finland.
