Need Urgent Advice: UNC Chapel Hill vs UW Madison (Tight Deadline + Loan Concern)

Hello everyone, I'm an international student stuck in a tricky spot and need advice. I've got admits from:

1. UNC Chapel Hill (MS in Information Science) - $72K tuition fees. Ranked #2 globally, and it's my dream school. But there's a catch- no scholarship available (deadlines passed long back), and I'll be taking full education loan covering tution and living expenses.

Deadline to accept offer and pay deposit: April 15.

1. UW Madison (MS in Information) - $36K tuition fees, but waiting for official admit letter (they need undergrad transcripts to be verified first). My undergrad instituite takes 2-3 weeks to send transcripts, and UW Madison takes another 2-3 weeks to process them. By the time I get official admit, UNC's deadline will have passed.

Note: UW Madison won't accept transcripts sent by students in any case.

I'm stuck - UNC is my top choice, but it's expensive, and I don't want to lose both options.

What should I do?
