Unless you got out of the Corps in the last couple of years it has expired. You have to certify that you are still doing a job that requires the clearance every couple of years. If I remember correctly I believe the TS is every 5 years and a Secret is 10 years, but I've had to renew my Secret several times over the last 6 for my current job.
