The purpose of a Danish visa is to control the number of people who can visit and live in Denmark or in other Schengen countries. Schengen countries work together to decide which visa requirement applies to various nationalities.
A Danish or Schengen Visa allows you to visit Schengen countries including Denmark for a limited time. If you want to extend your stay in Denmark, then you must file an application for a residence permit in Denmark. (Please contact Pathways Visa for more information.)
The Immigration Service controls Danish immigration. They will turn down a visa application if they suspect that a certain applicant for a Danish visa intends to permanently stay in the country.
