If you became a Norwegian citizen at birth and you do not live in Norway for at least two years, or in Nordic countries for at least seven years, before you turn 22, you must apply to keep your Norwegian citizenship.

Application requirements 

You must have stayed in Norway for a total of six months. These six months can consist of several short stays/holidays. 

Exemptions to the requirement for six months in Norway 

If you have not stayed in Norway for a total of six months, you can still keep your Norwegian citizenship if you have have a strong connection to Norway. When the UDI decides whether you have a strong connection, we will put emphasis on whether you are currently living in Norway, or you have by mistake been issued a Norwegian passport that is valid after you turn 22. 

When should you apply?

You must apply before you turn 22. If you apply after you turn 22, we can nevertheless consider your application if you cannot be blamed for failing to meet the deadline, or if it would be unreasonable if you were to lose your Norwegian citizenship. 

If you turned 22 before 1 September 2006, special rules apply. Please contact the UDI to clarify what rules apply in such cases.   

Applications for children under the age of 18 

If you are under the age of 18, your parents must apply on your behalf. Both your parents must sign the application, unless one of them has sole parental responsibility. An appointed guardian can also submit such applications. If you are over the age of 12, you must consent to an application being submitted on your behalf.
