Register at the municipality administration (commune)
You must, upon arrival in Belgium and within 8 days, register at the municipality of the place where you will be residing. This is an absolute prerequisite to opening a bank account (which is also something you will need to do).
Register with a health insurance fund (mutuelle) (if you are a foreign student)
Health care insurance is a part of the Belgian Social Security system. To benefit, you must join a health insurance fund which will reimburse your medical costs. To take you on, they will need a written certification of employment signed by UCL. Several funds have a secretariat in Louvain-la-Neuve : Mutualité chrétienne du Brabant wallon and Partenamut.
