once my docs are "accepted" (as opposed to them requesting the same doc again) it has taken only a few days each time. This time it took longer to get the docs accepted and I don't know why.
the replies below are derps. I've never had it take more than a few days. This is just right because of the number of times they requested the same documents again.
Example: I appended the pdf for my exit flight to the pdf of my entry flight and it was kicked back. I manually added a sentence explaining that both itineraries were in the pdf and then it went through. Not sure if it was an automated rejection or a lazy reviewer.
