They certainly are not doing enough! A first step to reassure their own students would be to guarantee all international students receive their first choice for in-person classes (i.e. by giving them first priority during pre-registration). In the long-term, UChicago should also be filing legal challenges against the regulations, like Harvard and MIT. I really hope UChicago gets off of their feet and takes action because to just tacitly comply is tantamount to alignment with hate.
