Coming to Gent
Getting In
If you are coming from outside of Europe it is likely that you will be landing in Brussels. There is a train station in the lowest level of the airport, the Train machines do not take non-European debit/credit cards so you will have to go to the desk and ask for a ticket to Gent. Look on the terminals for a train to Gent-SP. If you are arriving very late at night, it might be possible that you will have to take a train to Brussels Central and transfer onto a train headed to Gent-SP there. Gent has two train stations, Gent-Dampoort and Gent-Sint-Pieters. You always want to get off at Gent-Sint-Pieters. From there you can take a bus or a tram to wherever you are trying to get to.
Registration
You will have to register as a student at UGent at the University Forum (UFO) Building. A large glass building located at 25 Sint-Pietersnieuwstraat. You'll need to bring EVERYTHING you have with you, and they will likely also request things you don't have. A simple statement of "this is everything I have" is usually enough, and they will take a picture of you and hand you a student ID card.
