If your clearance status is active and clear, you do not need to submit prints again. To find out if you are active and in the system contact the local CCL office and ask to check your clearance status. If clear the office staff will give you your LIS personnel number and status. If you are clear and active write a note with your application that you are clear along with your LIS Personnel number and clearance status.
Note that if you previously worked for a facility over two years ago your clearance may have expired. Call. your local CCL office and check.
