Retention of Danish citizenship
You can apply for retention of Danish citizenship it you were born as a Danish citizen abroad and have another citizenship than Danish. You cannot apply for retention of Danish citizenship until you are 21 years old. The requirements for retention must be fulfilled by the time you turn 22 years old at the latest.
The conditions for retaining your Danish citizenship are always based on a concrete assessment. As a rule, you automatically fulfil the conditions for retaining your Danish citizenship if you either:
- have been registered as residing in Denmark for at least three consecutive months
- have resided in Denmark for a total of 12 months from birth until you are 22 years old.
This does not apply, however, to people who only have Danish citizenship or were born in Denmark.
Danes Worldwide recommend that, for the sake of good order, that Danish children born abroad apply for retention of Danish citizenship.

Reacquisition of Danish citizenship

As a result of the change, Denmark implemented a five-year window, which allows a person to submit a declaration to reacquire their Danish citizenship, if it was forfeitted before 1. of September 2020. This time-window has been prolonged until the 1. of Juli 2026.
