Thank you. Seems like there is some 3-4 weeks delay. Sigh. Might just be simpler to decline ITA and wait for invite again. I am going to mail the FBI tomorrow again, and let me see what they say.@wickerman see this thread about FBI PCC processing. Especially note the people submitted LOE with their applications and got extensions of deadlines to submit their delayed FBI PCCs:
