Hi, I have been offered a full tuition waiver and monthly stipend (with TA) at Wisconsin. Also, I was told that the department does not distinguish between funded and non-funded students, hence everyone is eligible to apply for TA postions during the start of the semester, and most of them end up getting it. Since the undergraduate enrollment is huge, there are a lot of TA opportunities. By tuition, I meant tuition waiver and not the difference!
But if weather is a concern, I can understand that since Wisconsin weather is harsh. I am also an international student, and I completely understand that.
All the best with your decision!
