If you are studying at AUAS and want to do an internship as part of your study programme, you do not need a work permit. Instead, you need to sign an internship agreement with AUAS and your internship employer.
You might need a specific health insurance type. This depends on the amount of money you receive from your internship. If you fail to take out correct health insurance you might receive a high fine.
This handy tool tells you the permits you need based on your situation.
