Leave of Absence
During the re-registration period you have the opportunity to take a leave of absence in exceptional cases. You stay registered in such cases but the semesters on leave do not count as study semesters. There is a reduced semester contribution fee to be paid for a semester off. This semester contribution fee does not cover the NRW semester ticket. You are also not allowed to take any examinations during your semester off.
Please note: even if you don't study- your semester on leave of absence is nevertheless added when the duration of your stay in Germany is calculated!
