I am waiting for DOE level L clearance to work at a company that makes nuclear components. sf 86 was submitted June 26, 2016 and I was told it was released to the DOE on 8/8/16. The NNSA applicant tracking system shows Investigation Requested on 8/16/16 and that is all I know. I don't think any references have been contacted, nor have I been contacted by any investigator. I was told at the time of my interview that security clearance can take 3-6 months though I know of one that took a full year in 2015. The crazy thing is 10 or more of us were offered the position at the same time, one guy had his clearance in 2 1/2 months while another guy had his in 4 months and others have already started on the job as well. I contacted the hiring company and was told my case was still pending. I am just worried my case is lost in the system somewhere. Any ideas?
