The key thing with a circumstance like yours is to deal with the right people. If your child's accomdation is with a private provider it has nothing to do with the University. This is one of the 'adult responsibilities' students are supposed to start to learn. But I would be stunned if an institution could commit - in writing - to its plans before July (mine wont). Right now it is wagon circling. Oh, but don't worry if you don't get accodation untl a few weeks before it 'opens' (if places were able to teach 'in person'). The drop off of international students will be so massive, there is going to be no shortfall of accomdation!
