Who has to pay a deposit?
You are required to pay a DKK 2.000,- deposit, if you are an independent student (employee, student etc.) and fall under the category ‘S’ in your municipality’s description. You are exempt from paying deposit, if you have a residence permit as an au pair in Denmark.
You can have your deposit back if you pass the module within the deadline. If you do not pass the module within the deadline, you will lose your deposit and you will have to pay a new deposit if you wish to continue to the next module.

You are not required to pay a deposit, if you are under the integration program. In this case, you are under the category ‘I’.
