Question: how often do i have to renew my security clearance?
Answer: HOW LONG ARE SECURITY CLEARANCES VALID? A Periodic Reinvestigation (PR) is required every 5 years for a TOP SECRET Clearance, 10 years for a SECRET Clearance or 15 years for a CONFIDENTIAL Clearance. However, civilian and military personnel of DOD can be randomly reinvestigated before they are due for a PR.
