If your stay in Belgium is less than 90 days, we take care of your registration.
If you want to stay in Belgium more than 90 days, you can stay in Stilleuven for a few weeks until you find a more permanent accomodation. As a EU-citizen you have to register in the city hall of Leuven before the 90th day of your stay. As a non-EU citizen you have to register within a period of 8 days (somewhat flexible).
You can only obtain a bank account in Belgium when you have a permanent address.
