Waitlist reply window

Hi!
I’m currently on the waitlist at Chicago.
If (a big IF) I am accepted (say, in the middle of May), how many days will I have to enroll?
I have not yet visited campus, and I don’t know if I’ll be able to switch to Chicago if I don’t have time to visit.
Thanks!

I heard that colleges usually give about 2 days for you to commit before they move on to someone else.

They gave my D three days because we request to visit the school first. We took the flight the next day and after the overnight we have to commit right then right there. That was seven years ago. That year they took 15 off the list out of 3000ish.
