# CBP Clarifies Security Clearance Validity

Government contractors transitioning to cleared positions within U.S. Customs and Border Protection (CBP) should be aware that existing Department of Defense (DoD) security clearances and full-scope background investigations, including TS/SCI, generally remain valid for up to two years after leaving a cleared role. However, CBP may require a new Tier 5 background investigation if the transition occurs beyond this two-year window or based on their internal policies. This underscores the need for contractors and procurement professionals to closely monitor clearance timelines and agency-specific requirements when managing personnel transitions involving sensitive or classified roles.

- **Why this matters:** Understanding clearance validity periods helps avoid delays in onboarding cleared personnel and ensures compliance with CBP security protocols.
- Procurement teams should verify the currency of security clearances for contractors moving into CBP roles, especially if more than two years have elapsed since their last investigation.
- Contractors should plan for potential re-investigations to maintain eligibility for cleared positions within CBP.
- Agencies and contractors can reduce operational risk by aligning personnel security processes with CBP’s clearance requirements and timelines.

> Depends on when they actually start doing the background check. If it’s within 2 years, you’re fine. 2.5? Toss up. They might ask you to redo it anyways
