Advantages and disadvantages of dual citizenship.

Dual citizenship has become available after Denmark changed its legislation, making it possible from the Danish side to have dual citizenship or even three or more citizenships. For Danes living abroad, for example in the USA or Germany, this means they can obtain American citizenship without losing their Danish citizenship, and vice versa. This has opened up a world of advantages for global Danes, but it also brings certain complexities and perhaps even disadvantages for the individual.

Family reunification is one of the topics we have dealt with the most politically and in legal counseling. The rules are complicated, and there are relatively frequent changes both from the Danish and European side, which have significant implications for our members’ ability to bring their partners to Denmark.
