I went through an all-in-one clinic that required an initial appointment when I met with the doctor, the application was completed, fingerprints, photo, etc. A second (televideo) appointment was also required. Here's my timeline:
12/12/2017: initial appointment, application, etc. completed
12/21/2017: second (televideo) appointment
12/22/2017: credit card charged by IDPH
02/26/2018: sent an email to IDPH inquiring about status. Later that day I received an email telling me that they are processing applications in the order they are received and that they are too busy to respond to emails regarding status updates.
03/05/2018: received a letter via snail mail saying that my application was "incomplete" and that it was filled out by a physician who does not have the necessary licenses to complete the form, which was bullshit and a clerical error on IDPH's part. I wasn't surprised. Classic State of Illinois stupidity. Lost a whole week over their mistake.
03/06/2018: first thing in the morning I faxed the letter over to the clinic I applied through. They told me this was happening A LOT. Way to go, Illinois. They resubmitted the physician's form via email immediately, and told me I will receive my card in 2-3 weeks (regular time, not business days, but still nets out to 10-15 business days).
03/13/2018: card received!! I was surprised that it arrived exactly one week later instead of 2-3 weeks.
I start my timeline the day after my 2nd doc appointment, since that is also the day my credit card was charged and therefore when IDPH received my application. Given that, it took 82 days. Would have been 75 if IDPH wouldn't have made their stupid mistake. Also, I do find it odd that I heard absolutely nothing until I emailed them and they responded with the generic we're too busy email, but then suddenly they sent me a letter. It probably would have just sat there gathering dust if I didn't shake the tree.
And, it meant nothing regarding when they charged my credit card. That was the first thing they did, and the wait was still 81 days after that.
