Really great to see that all these good folks from other states are trying to help even though they have no idea how it works here.
I had a denial because of felony conviction. Called the number spoke with the Democrat and got it straightened out. Had to go to county to get proof that I did not have a Felony conviction. Sent the paperwork in and got my FOID a couple weeks later.
You have to understand, the Democrats are still running the FOID system so they will NOT go out of their way to help you get your card. But if you are polite and professional they will do their job and get it sent to you. If they got you mixed up with someone else, it may be as simple as you sending in a picture of your drivers license and social. Talk to them. As a rule they do not try to deny legit people. They just get info on everyone in the country with your name and do not feel it their job to prove you innocent and qualified. That is up to you. Call them first, they were actually nice when I talked to them. Did not need to, record conversations, (illegal in ILL), or spend money on lawyers, just sent them the paperwork they asked for and they gave me my FOID.
