It's a waitlist but it does not mean you will actually end up on the final waitlist that is compiled in early June. You can still be rejected from this list. On the bright side though, you can still gain admission in the interim b/w now and the time the waitlist is compiled as people w/multiple acceptances start narrowing down their choices in the next few months. UIC seems to admit a large number of people that have multiple acceptances as they go quite deep into their final waitlist.
