When you study abroad, in principle you will need to arrange your own accommodation. However, if you register with the guest university in good time it will often be possible to arrange a (furnished) room via the campus. In general there are websites that can help you find a room off the university terrain. Don't hesitate to explore the experiences of other students who have been there before you.

If your room in Nijmegen is suitable, you can rent it out for the period you are away via the housing department of the central International Office. They can mediate in finding accommodation for visiting international students.
