Reached the age of 22 between 1 October 2001 and 31 August 2006

If you reached the age of 22 between 1 October 2001 and 31 August 2006, then you automatically lost your Norwegian citizenship on your 22nd birthday if you:

acquired Norwegian citizenship when you were born, and
were born outside Norway, and
hold another citizenship in addition to Norwegian, and
did not reside in Norway when you reached the age of 22, and
had not resided Norway long enough before reaching the age of 22.

You have resided long enough in Norway if you have:

resided in Norway for at least two years before reaching the age of 12, or
attended school or been employed in Norway or other Nordic countries for a total of seven years before reaching the age of 22, or
resided in Norway or other Nordic countries for a total of seven years before reaching the age of 22, or
had yearly holiday stays in Norway averaging more than one month throughout most of your childhood, or
had some holiday stays of over one month and at least one extended stay of longer than two months in Norway after reaching the age of 12 and before the age of 22, or
completed military service in the Norwegian Armed Forces before reaching the age of 22.

You do not lose your citizenship, however, if you have applied to retain your Norwegian citizenship and you have received a letter of decision from UDI affirming that you were allowed to retain your Norwegian citizenship after reaching 22 years of age (retention of citizenship).
