As soon as you have made the decision to study in Holland, you will need to arrange quite a few things before arrival, upon arrival and during your studies.
It is important to make your application in time, that means usually before 1st May and even earlier! Always check the website of the institution !
Then try to find some information about practical details like finding an accomodation. As this is not necessarily easy, we advise you to contact your university. Check some specialized websites in Holland or contact the Luxembourg students’association in the Netherlands (LSNL).
