I heard they needed to interview my neighbors and research my distant family members and such so yea I was suprised it happened so fast as well. Not quite sure what the classifier did for me but I can't complain. All my immediate family are US citizens, no criminal record, never got a traffic ticket, paid all my credit card bills on time, never did drugs. I looked good on paper I suppose.
I am a little disapointed I won't be a nuke, but still satisfied with my job rating. Thanks folks, even though I'm not a nuke I can't help but love this forum.
Nuke is generally secret level clearance, but you don't do anything extra for Top secret security clearance, just some paperwork and higher level of scrutiny I suppose.
