I had heard before that Belgium is renowned throughout Europe for being so thoroughly bureaucratic. I didn’t want to believe it (after all, Latin countries have exacly the same problem), but, boy, were they right. I won’t rant here about the immigration/residence permit procedures, which are excruciating as usual, but even simple stuff like ordering cable TV and getting WLAN at our flat has been an ordeal. The bureaucracy at the school has been the exception that confirms the rule, though, they’ve been spotless.
My advice: if you move here, make sure you don’t need anything urgently.
