It shouldn't be nerve wrecking at all. There are 34% of November applicants who haven't received AOR yet. Your application was received at the end of the month, so if 99% of applicants received AOR and not you, then I'd say you should worry. Right now all you need to do is wait.Received Nov 29th, no AOR yet.
This is nerve wrecking. Hopefully it’s not incomplete at this point!
