College Conundrum

So, I was waitlisted from Stevens Institute of Technology, which was a first choice for me. Instead, I was accepted to NYU, so I ended up putting a deposit in for it.
However, just a few hours ago, I received a phone call from Stevens telling me that I had been accepted from the waitlist. I told the caller that I had already deposited for NYU.
So I would just like to know: Can I still agree to attend Stevens even though I put in a deposit and completed my housing application and everything?

Of course you can! Congrats. But why is this in the Lehigh thread?

Oh sorry lol, didn’t see that
