I have been calling since Tuesday. Each time I was told they are opening July 27th but cannot find me in the database. Mine was supposed to be delivered 27th. This is driving me crazy. As the USPS tracking indicated it was delivered late August after I called and questioned as the shipping date is July 23. And I used 3-day shipping. I was told by the mail man that it was delivered July 27th and he just forgot to update it in the system. The FBI rep. said he can only confirm receiving my application if he can locate me in the system, which is after they open the package. If they keep this pace, I wonder if it is gonna be 4,5 months in the feature to get the PCC as there are too many unprocessed applications. So for those who are in the US and has not received invitation, get prepared early.
