If you already have a current security clearance at the same level and with the same federal agency (e.g., DoD), JT4 Security can take ownership of the clearance. Also, a reciprocity request can be made if the clearance is from the Department of Energy. When a clearance is inactivated due to switching jobs or leaving the military, it must be reinstated within 24 months of the departure date or it is no longer valid. If the clearance is outside the last investigation date, an update will be required.
