Accepted roommates are residents who have requested and accepted each other when completing their UHR applications. During the application process you can send another UHR applicant a roommate request. If they agree, then you both are accepted roommates. The same applies if you agree to another applicant’s request.
Roommates should be in the same class standing category (sophomores with sophomores, juniors/seniors with other upperclassmen and graduate students with other grads) and of the same gender.
