I sent TWO packages at different dates because i thought the first package would be rejected since i have done the fingerprinting myself while the second package i used the police.
BOTH were accepted by FBI, BOTH were done on normal (not bad quality) A4 paper, there was no hard paper used. Good luck
When I had my fingerprints taken the guy had the fingerprint card printed on hard paper, but the surface of the paper was not rough like that of the hard paper used for drawing - it was smooth.

For my case, I had called them a couple of business days AFTER the card was chard. They confirmed that the fingerprints were ok and that the reports were dispatched on the previous day (1 business day after card charged).
I know this must have been asked a lot of times in this forum, but I could not find the info .... what is the number to dial in order to get info on one's FBI PCC application?
