I called the customer service line twice and they told me that it might take 6 to 8 weeks to get reply because of the backlog. The first time they said there were three days of server down. Anyway I bet it will take more than 8 weeks. I sent request also at the end of Oct and haven't got reply yet.
But to whom who pursuits the inquiry of name check, recently I talked to my lawyer and he told me the cases of two of his clients were delayed for very long time because of this (BCSCIS? I forgot the name of it) background check inside USCIS not FBI name check because they are waiting for the response of some kind of inquiry from interpol (international police) and have no idea when they will receive it. What a nightmare!!
