CONCUR! Keep your SF-86s so each new clearance/investigation is just an update and not a clean slate. Makes the work you'll have to do easier and even if you don't have your last input the investigator will and any deltas between the two packages (outside of updates) will draw scrutiny. Also, don't clear out your amazon address list too often as it can be helpful when you need to remember every place you ever lived. My last investigation was the first one that put all my college housing changes outside the window so it was a bit simpler. My overseas "address" from living in Sasebo base housing still got funny looks but such is life.Keep a copy of your answers, those packets will get lost and you’ll have to start the process over again. Probably twice...
