In my acceptance letter, it specifically says "self-funded." It's probably because I am an international student whose first language isn't English. I emailed the school, and was told that a TAship would be possible if I pass the SPEAK test. But it's unclear to me if funding would occur in the first year or afterwards. They did suggest me applying for Graduate Assistantships.
However, I am not sure if Buffalo funds all their incoming students.
Also, I have been waitlisted for funding in a few schools. It IS frustrating.
