Hi everyone I've been admitted to Computer Science and Engineering Ph.D. Program at UB for Fall 2014. I am from Iran and I don't have funding at the moment. I am planning to finance my education by myself for first semester, hoping that I receive funding for following semesters. I was wondering how much is it affordable to live without funding? I also want to know that how much can I count on getting TA/RA in following semesters (or even from first semester,or at least a tuition waive)? Other than that, is it possible to make living on a job as a student in Buffalo? I'd be thankful if anybody could answer these. Thanks
