If you are a citizen of a Nordic country you can freely live and work in Denmark. If you are a citizen from an EU or EEA country, or Switzerland, you can start to work in Denmark and then apply for a registration certificate from:
The State Administration
possibly through:
The International Citizen Service.

If you are a citizen of a country that is outside the EU or EEA, and you are posted by an enterprise from a EU country, you have to seek further advise at the State Administration.

If you are a citizen of a country that is outside the EU or EEA, and you are not covered by the regulations on posting of workers, you always have to apply for a work and residence permit before starting work in Denmark. You can read more and send your application online to the immigration authorities at:
