Illinois does not honor any other state's concealed carry law. Period. I live here and have a CC permit, and also a Utah non resident to help with travel. Illinois's concealed carry is among the most restrictive in the nation, and was only passed at the last minute pending a lawsuit. Be careful carrying here if you are not a resident with a CCW or hold an Illinois non resident CCW, which, buy the way, cost $300, double the resident cost.
