I had been told some time ago that my prior military service connected TS clearance would trigger a delay and further “administrative” review…..just another “thank you” from our government.Several things may cause this like a former arrest (no conviction) or someone with a same/similar name.
Were this me, I’d apply for a UPIN # in order to clear the FBI NICS check quickly.

Sucks that we have to do this at all, I agree. But maybe make the best with what we’ve got for now.
