Use it, or lose it. That’s how Uncle Sam currently feels about having access to classified information. Your eligibility to access cleared information is always based on need-to-know. If you left your clearance when you left your last job, you’re still ‘current’ – assuming your investigation hasn’t expired. Simply accept a new cleared position and your security officer can easily reinstate your access in the Joint Personnel Adjudication System (JPAS).
If your clearance has already expired, you’ll need to start the process over. But list yourself as ‘clearable’ along with the date of your expired investigation. Some recruiters may be willing to take a chance on a ‘sure thing.’
