You must apply for a student visa if you are a non-EU citizen and wish to study in Denmark for a period longer than three months. This will enable you to remain in Denmark for the entire duration of your course and continue your education there. Your student visa permits you to travel to Denmark for up to 30 days (1 month) prior to the start of your academic programme and for up to 14 days (2 weeks) following its conclusion. If you haven't secured employment and are eligible to apply for a work and residence permit before your studies are finished, you must leave Denmark.
