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.
The Department of Defense (DOD) operates its security program separate from other government agencies, with its own procedures and standards. A Top Secret Clearance with the Department of Energy, for example, would not necessarily transfer to DOD. In the United States military, only United States citizens can be granted a DOD security clearance. Need to Know Required. Merely having a certain level of security clearance does not mean you are authorized to view classified information.
