Bangor University said it had a support office that helped international students with every aspect of life, including “guidance on available accommodation” and welfare issues concerning their families.
Swansea University said it was “saddened by any reports of students staying in inappropriate or unsuitable spaces”.
It said it was committed to providing comprehensive support and guidance to ensure all international students had access to suitable accommodation.
The University of South Wales said that it was concerned to hear about these individual cases and that international students are informed of the high demand for private sector accommodation in the area, particularly for those with dependants and families, and the increase in costs, before they travel.
The UK government said it was “fully focused on striking the right balance between acting decisively to bring down net migration and attracting the best and brightest students to study at our universities”.
