1 & 2. There are no separate transfer dorms. You will be allowed to choose from the sophomore housing options (Warren, Nugent, Davison, Sharp, some RAHPs, some STACwyck, Blitman… I believe). You will live intermixed with the returning students.
3. I don’t really know, but one year Nugent had a concentration of Asian residents. You might think to contact groups like CASA (Chinese American Student Association) to see where the rising sophomores are living.
