No, the Student is responsible for their own space and cleaning up after themselves.
You should be a welcoming Host but the Student is responsible for taking care of their own room. Make your expectations and house rules very clear when the Student arrives. If the Student is not following your rules, remind them as often as you need to. Please remember that many Students may have never cleaned or done their own laundry before and may not know how. Keep cultural differences in mind and consider showing your Student how to use the washing machine, clean, where to find the supplies and what you expect for frequency and standards. You may need to follow up and give them feedback (and offer some kind patience) as they learn.
