Visa and Travel

Visa 

General Information

You can check whether you need a visa to visit Denmark. In particular, citizens from EU/EEA do not need a visa to enter Denmark. Visas are obtained in the consulates or embassies of Denmark in the country of origin. Requirements and processing times may depend on the origin of the visitor. We strongly recommend investigating the concrete conditions for your case well in advance. In particular, invitation letter requests should be sent early enough.

If you need a visa, see details on how to apply (Ministry of Foreign Affairs of Denmark).
