Unlike one of my B1/B2 visas, there isn't a clearance received annotation this time... only the flu vaccine waiver thing. Now I am not even sure if I was actually in SAO, even though I was told at the interview that I got flagged and they need to send the case to DC...
From the few pieces of information, I could only speculate whatever process they needed to do, was done on 8/31 (about a month after the interview), then they just sat on my case for like 6 weeks until my lawyers followed up twice. In the first reply they were saying I needed an USCIS waiver, which was very confusing to us (retrospectively, they were probably talking about the flu vaccine waiver since my medical was in June when it was waived, but the most recent processing was beginning of October; though it's something they give, not by me requesting), then the lawyers followed up again to clarify, this time they said it's pending a CO review. Both replies were standard form responses though...
Luckily, just as we were contemplating our options, the request for passport email came.
@ak47 Luckily, I was able to scrape by by a hair, my medical expires in mid December, and I will be landing in about two weeks.
