Since 2016 there has been a fee for processing of certain applications.

All cases that have to do with refugees are free of fees – the only exception is refugees applying for permanent residency. Complaints and requests for reopening concerning asylum and humanitarian residence permit are also free of fees.

In cases of doubt, you must pay forst and then get reimbursed later (minus an administration fee).
