I got dual citizenship when I was born, and am under the age of 22
If you became a Norwegian citizen automatically when you were born and you have not lived in Norway for at least two years, or in another Nordic country for at least seven years, before you turn 22 years, you will still lose your Norwegian citizenship automatically when you turn 22. These rules will not be changed.
This is only the case if you are also a citizen of another country. If you are only a Norwegian citizen, you will keep your Norwegian citizenship automatically, even if you have never lived in Norway.
If you are in the group that might lose its Norwegian citizenship, and you wish to keep it, you must apply to keep your Norwegian citizenship before you turn 22.
If you have lived in Norway for at least two years, or in another Nordic country for at least seven years, before you turn 22, you will not lose your Norwegian citizenship. You do not need to hand in an application.
