Your Facility Security Officer (FSO) may inquire about the status of your security clearance. All National Industrial Security Program (NISP) cleared contractors use JPAS (official personnel security clearance database management system for DoD and other government users).
The Personnel Security Investigation (PSI) on which the clearance is based can be either "current" or "expired." PSIs are current if they are not more than five years old for a Top Secret clearance, 10 years old for a Secret clearance, or 15 years old for a Confidential clearance. Generally, if the PSI is out-of-date (expired) or there has been a break-in-service of two years or more, a person must be nominated for a new clearance and must complete a new application in the same manner as a person who never had a clearance.
