This is New Jersey government you are talking about. There has never been any joined-up-thinking here. The process says check the mental health records going back 10 years for an initial application, and renewals are to be treated just like initial applications.
It doesn't matter to them that you lived in NY 8-10 years ago and they got those records before. They have to get them again - you know, just in case 8-10 year old history changed since they last got a copy of those records.
It required dragging them kicking and screaming to accept that being fingerprinted every time you applied for a PCH was pointless. You know, fingerprints that they use to identify you because everybody's are unique and unchanging have to be taken again, just in case they changed.
