Last summer, I was denied a TS/SCI clearance. I failed the polygraph lifestyle portion, which was my fault, I got nervous and omitted information. This was all for an internship as I am still in college.
Since then, I have applied at two different places, a contractor and a research lab (also internships). In both cases, I have passed the initial qualifications, but declined employment in the background investigation phase. One was for a Secret clearance, the other wasn’t for a clearance at all, simply a background check. I have a spotless record, aside from a somewhat large speeding ticket (16 over), but it seems like I am getting declined solely for being denied in the past.
Is being denied that first time disqualifying me in my search for employment? If so, how long should I wait to apply for a clearance? Is this going to put a black mark on me for future cleared positions? I’m scared that my initial mistake will cost me my whole career.
