I am waiting for mine also, so I am not the one to provide the definitive answer. But after everything is filled out there is a spot in RED that says "You currently do not have any certificates in Airmen." I assume that it should show there when available. I also read that they will send an email notification
After you login and hit the TOS button (...for the 19-thousanth time) you'll eventually see it on the 'your exsiting applications' line under the box 'certificate type'...should show up in a week, unless the TSA uncovers that smuggling conviction. =-)
Congratulations microraptor! I anticipate the follow up question might be, "When will my actual license arrive in the mail? Based on my experience thus far, it might take a while. I took my test on 8/31, applied through IACRA on 9/6, and I have yet to receive my official "hard card". However, I expect it will be any time now, as I know some friends who applied a few days before I, and just received their cards. You might be lucky enough to receive yours by Christmas. Best of luck.
