Well...I took my PAL course in 2004...signed up for the Restricted as well at the same time but didn't end up taking it due to family illness.
I decided to take my Restricted this past summer (2022) in August. Got back the signed documents from CFO's office in September, sent it to CFC by Fedex overnight which was received September 21. Been sitting there since, and I just logged into IWS and it still shows my last renewal of my PAL in 2018. I am hoping my application changes status soon...at least they can acknowledge they actually received it and it didn't fall behind someone's desk or something.
I remember in 2004 the time it took for me to get the PAL from the time I dropped off the signed application by snail mail to the point I got my PAL card in my mailbox was a little under six weeks. I have no illusions I will get that same level of service around.
