Registering as new foreigner in Brussels
I (EU citizen) will be staying at Brussels for a duration of 94 days. As I understand, every foreigner staying for longer than 3 months/90 days will need not only to signal his or her presence in Belgium, but also officially register - I'm not sure how stricly this rule is applied, but I'm guessing that means that I will have to register and not just "signal" my presence.
I'm at a bit of loss though, because I've read at the official website of Brussels that I can only register by appointment and the next open appointment is in April, after I've already left.
I now consider going to the administration office without an appointment, taking all relevant documents with me (further question - see below) and basically ask them what I should do as I'll need to inform them of my stay within 8 business days anyways.
Does that make sense or is there any other (better) action I should take? Can I go to any of the administration offices? The central one if the one closest to me, but I wonder whether it would make more sense to go to one of the smaller ones?
What documents do I need? As I understand, I'll need my ID/passport, 2 pictures and my working contract. Will I also need bring my lease contract?
