I have been filling out my paperwork and I am on form 4 and I was confused on a few things. What should I list as reason for being fingerprinted (i.e. NFA transfer, weapon tranfer). Also, I have taken a frontal photo of myself from shoulders up and printed it in a 2X2 sqaure. Is this good enough or does it need to be bigger? Last, should I glue it to the form?
