I hope that they change the policy to make the FP review results valid for up to 24 months. Let's face it, it's CIS problem.
Asking for a 2nd FP only creates unnecessary delay.
Best solution would be to retain the FP images so they could run the check anytime they want.
Actually, this is something that puzzles me. Does the FBI flush the FP images? Maybe not. They want to keep the FP images of as many people as they can get for future use.
