Hopefully hkim gets his PR this summer, so all the international talk is moot. Then at a minimum he will qualify for UIUC’s Illinois Promise which is a full ride, and he can target other schools from there. https://osfa.illinois.edu/types-of-aid/other-aid/illinois-promise/
If he doesn’t get his PR by EDI time, I expect he will look at the schools that consider DACAs as domestic students: e.g., Emory, Pomona, Tufts, Oberlin and Swat. If anyone has any schools to add to that list please do. NU does, but Hkim was denied admission there this year, so that will probably not be an ED target next fall, nor perhaps on the list at all. We shall see what the next 6 months bring hkim.
