Just a hat tip for anyone with an IL license who applies for a license elsewhere. Do it way, way, way in advance.
Unlike any other state I've had the pleasure to deal with, IL license verification isn't online at all. It requires you to mail them a physical letter and check. They then take a month to process the check. And then (only after the check is deposited) apparently take up to a month to process the request and submit the certification that you're licensed and in good standing. This is the last thing holding up my license in the state I'm moving to. If you email to ask for an update, they'll submit and automated response that they're too busy to respond to most of their emails. If you call and ask, they send to to a call center where they state they are unable to forward you to anyone that can help with your issue and they'll get to it when they get to it.
I've filed a complaint with the Office of Executive Inspector General for the Agencies of the Illinois Governor at this point.
