It is a fundamental principle of the Danish legislation that dual nationality must be restricted as much as possible.
Dual nationality is, of course, accepted in various situations, such as if persons are born with dual nationality. As an example it can be mentioned that persons born in the USA or Canada by Danish parents also acquire US or Canadian nationality at birth on the basis of the so-called territorial principle.
The Danish principle of avoiding dual nationality as much as possible is in accordance with the 1997 European Convention on Nationality. The Convention makes the contracting states free to decide the issue of dual nationality.
Due to the Danish principle of avoiding dual nationality as much as possible, you will only be listed in a naturalisation bill if you are willing to renounce your present nationality.
It depends on the nationality legislation of your country of origin whether you will automatically lose your current nationality when you become a Danish national, or whether you have to apply to the authorities of your country of origin to be released from your present nationality.
The Ministry of Justice has details about the nationality legislation in your country of origin. If you are from a country where you will not automatically lose your nationality when you are awarded a foreign nationality and where you can apply to the authorities of your country of origin to be released from your present nationality, the Ministry will make it a condition that you are released from your present nationality.
When Parliament has adopted the naturalisation bill in which you are listed and the act has entered into force, the Ministry of Justice will send you a special notice that you will only be awarded Danish nationality after having proved that you have been released from your present nationality.
The Ministry will fix a deadline for your release from your present nationality. If you fail to prove before the deadline given that you have been released from your present nationality, you will not become a Danish national on the basis of the bill in which you were listed.
Instead you may apply for Danish nationality once again and become listed in a new naturalisation bill if you satisfy the relevant conditions at that time.
In that connection you must expect that it will again be made a condition that you are released from your present nationality.
The following persons are not required to be released from their present nationality:
- Applicants who automatically lose their present nationality
- Applicants with refugee status
- Applicants from countries where experience shows that it is impossible or implies extreme difficulties to be released from nationality
- Applicants whose application for release from their present nationality has been refused
- Applicants who have proved that they have made a serious, but unsuccessful attempt to be released from their present nationality
For further details see section 4 of the Guidelines.
Due to the Danish principle of avoiding dual nationality as much as possible, you will automatically lose your Danish nationality if you acquire the nationality of another country upon application or express consent.
The same applies if you acquire a foreign nationality by entering the public service of another country.
You will not lose your Danish nationality if you acquire a foreign nationality automatically, for example by marriage.
For further details see section 7 of the Nationality Act.
