Do not know..I guess not
I have not received the approval yet.As long as it has not been taken up by the officer ,i think it really does not matter, but if it has already been assigned and the officer finds that the FP is not complete,he will put it back in the pile.Probably you have to call and request it to be reassigned back..That would be a delay.Anyway after two attempts of FP,if it does not clear, it is transferred to the local INS office for an interview.
