How long is a Luxembourg student residence permit valid and how is it renewed?

A Luxembourg student permit is granted for a minimum of one year, or for the duration of the study cycle where that is shorter. This keeps it aligned with your programme while you remain enrolled full time.

To continue, you apply for renewal within the two months before the permit expires, submitting documentation similar to the first application, including proof you are still enrolled and still have sufficient resources. Staying continuously enrolled and keeping your finances documented makes renewals smoother and protects the continuity of your stay.
