Admission into a Degree in Brussels

Hey there,
having just learned that it is most likely Brussels will be my home from next month, I have thought about joining a Degree course.
Nonetheless, my French is not quite there yet and I am slightly confused about the admission system and deadlines (I seem to understand that applying in august is possible, but since I have a foreign title I should have "converted" such document into the local system in june, which has obviously past). I have an International Baccalaureate degree (being international, I might not have to "convert" the title), a British BA and a Spanish MA. Any ideas? thanks!
