An update to my post from last month:
About a week ago I received a letter from the BATF that they could not complete the background check without my Social Security Number. So I immediately added my SSN to the form and returned it to them. Like I said in the post before, I had read on a few websites that you don't need to include your SSN.
Well yesterday, I went to the mailbox and inside was my brand new C&R FFL.
My advice to anyone applying is to make sure to include your SSN on the form. 19+ weeks is a LONG time to wait for something like this.
