Looking for some insight into what will happen to my clearance if I were to leave my job and go to a non-cleared job for a period of one year. My re-investigation was only 6 months ago. I currently hold a TS/SCI.
Your clearance would be administratively withdrawn and put into an inactive status. If you land another job within 24 months that requires the same level of clearance then it could be reactivated without having to undergo a new investigation, but you might have to fill out a new SF86 for review.
