You should bring your passport, two passport photos, and a copy of your Letter of Admission. Your application will then be treated within a week. To obtain a permit you must document that you will continue to study at the same institution. European students must bring an E128 form from their home country. The form can be obtained from your local municipality or consulate.
Residence permits are valid for one year.
If you require an extension, you will have to submit an attestation from the teacher or department to show that your studies are progressing satisfactorily. Please be aware that a course of study which takes a number of years to complete will not necessarily imply the right to an extension of a residence permit. When you leave Denmark for good, the residence permit must be returned to the Prefect of Copenhagen or to the State County of Copenhagen. If you are a student from a country outside Scandinavia and the EU you must apply for a residence permit if the stay in Denmark exceeds three months. Application for the residence permit MUST be made before leaving your home country, and you make the application through the Danish Embassy or Consulate in your country.
