Are late interviews for waitlist spot only?

[persenmi]

Here is the situation: I have already been accepted to a good school and put down the first deposit. However, today I received an interview invite from UPitt for late Feb. I am interested in attending one more interview but I would hate to dish out more cash only to compete for a spot on the waitlist. Does anybody know how this works? Does UPitt still have open seats?

You should probably contact the admission office at Pitt, if you want a valid/useful answer
