Give UIC a call. They can be notoriously bad at getting interviews out. I am a combined EM/IM intern at the program. I love the program, extremely strong ED training with fantastic attendings. Good exposure to everything. But last year I had to call them because I had yet to hear from them at the start of December. So drop them a line and ask them what the status of your application is?....It nevers hurts to show interest in the program.
