Hi,
How do you know when FBI completed your check and when they mailed out the PCC? Does FBI inform you in writing?
As others said, you need to call USA number 304-625-5590 or email to liaison@leo.gov to get the update. I called the number. If you send email, include your first name, last name, date of birth, and the date your application was delivered to FBI and you should get a response within two days. I would suggest that you make a call as the hold time is less than 5 min. Make sure you also ask them on applications from which dates are being currently processed.
Once you have the answer, post on this thread to help others.
