INS IIO is correct
They can tell looking at their monitor if the background checks have been completed yet. The AVM is a F$%%^ piece of crap.
I have seen many posts on this site which prove that.
My personal experience also proves the screwed up AVM.
I did my FP on 12.12.01 and AVM still says, " On Dec XX, ..Pending Review\'. My wife did her FP on 01.23.02 and her AVM changed to "Processing Resumed" on 01.25.02.
Go Figure!!
