I submitted on 4 August, received by FAA on 8 August. I was "in line to be reviewed" until 24 October 2016. On 24 October it changed to "with a provider". I was really excited. Yesterday, 31 October, I called and was told they didn't have my EKG. My AME then resent it electronically. I called today, 1 Nov, and they had received it and I am in the "hold que". According to the lady at OKC, the hold que is first in, first out.
I have no idea how much longer but I wish I would have asked OKC months ago if they had received my EKG, I never thought to ask.
What a bummer!
