Active and Current Clearances
The only way to have an active security clearance is to be in a job that actively requires it. Whether you quit or got laid off, you still have clearance eligibility, but it switches to ‘current’ status in a security clearance system of record. Of course, flags against your record will put a hiccup in your ability to maintain your security clearance. Leave a job with an unresolved security violation, and it will haunt you going forward. And while Continuous Vetting (CV) has made it a little murky for some, most clearance holders can still count on keeping a current clearance for two years after leaving their last cleared position. This is not just helpful for clearance holders. It saves the federal government time and money on re-doing the whole process. There are exceptions to the rule of course, but the system is increasingly changing to keep up with those outliers.
Maintaining a current security clearance when you’re in between jobs doesn’t mean you can just walk into any cleared facility and read classified information. Revoking clearance eligibility is a specific action tied to specific adjudicative guidelines. Removing eligibility always happens when someone leaves the government.
