Thanks everyone! It sounds like there are a few things he can do, either this year or next year. I talked to him today and he is feeling a lot better about everything. I think he was kind of on the fence about joining a frat anyways, due to the time commitments involved. So perhaps this will just give him a chance to think about it some more.
@guineagirl96 That is so encouraging, thanks! I know he has close friends in his dorm, and since everyone will still be living in the dorm it should be fine.
