Danish citizenship can be acquired either by birth, descent or by naturalisation. All children born to a Danish parent acquire Danish citizenship by birth automatically, whilst children of immigrants born in Denmark, can acquire Danish citizenship under certain conditions through a declaration submitted before the age of nineteen. In terms of naturalisation, this is a highly debated issue in Demark and currently one can apply after nine years of residency and a Danish language test.
Dual Citizenship was introduced in Denmark in 2014 when Parliament passed a law to allow citizens of Denmark the right to become citizens of another country without losing their Danish citizenship. The law no. 1496 of 23rd December 2014 entitled “Law amending Danish citizenship (acceptance of dual citizenship and payment of fee in cases regarding dual citizenship)” allows Danish nationals to acquire a second citizenship without the need to renounce their original citizenship. This law also allows foreign nationals to acquire Danish citizenship without having to renounce their original nationality. In addition, the law also stipulates that persons who lost their Danish citizenship before the amendment of the law, have a 5-year period where they have to reapply by declaration.
Danish law does not specify any consequences of non-registration or non-renunciation conditions. Danish citizens are allowed to hold dual citizenship without any special conditions.
