The commitment date for U Minn was May 1st. Do you have an approved extension? If not, I believe it’s on a space available basis after May 1.
You didn’t answer the previous question about affordability. Can you afford the extra $45k?
Scenario for what?
If you’re worried about the current political climate in the US, then Alberta is the answer.
If you’re asking about future employment opportunities, it’s hard to predict 4 years out but it’s unlikely to get any easier in the US IMO. I can’t speak for Canada as I’m unfamiliar with their rules for foreign students.
