Hello, I'm a freshman in college, currently dual majoring in Nuclear Engineering and Physics. Recently, it has been brought to my attention that to secure an internship in the nuclear (or some physics) fields, I would need to obtain level L security clearance with the DOE, and further on to get a job in the nuclear field, I would need to obtain level Q clearance. It is my understanding that these clearances require detailed background checks by the FBI, and detail your full personal history, including social media checks, interviews with family, friends, neighbors, etc, and that certain things will automatically block you from receiving the clearance. In the past, I've been pretty open about my drug use, very little on social media but it's widely known by friends and some family. Additionally, I was previously a political anarchist, and that included a disdain for the US governments, as well as any others. Currently I would describe myself as a libertarian, though I still appreciate non-violent anarchist policies. Additionally, my email address, as well as social media accounts share a name with this username. I don't know if that's something that the FBI would be concerned by. I'm not here to hear criticism for my drug use or my political leanings, but I would very much appreciate some thoughts on if I need to change my major, or what my options are. Of course I would never actually be a security risk, as I'm not a bad person, but do I have any chance convincing the FBI that? I posted this in career guidance because that's what I'm seeking, but it might be better if a mod moved it to the nuclear section, as that's where I feel I'll receive the most helpful insights. Sorry for the long-winded post, I felt it was necessary to provide that level of detail for a thorough and informed answer. Thanks for all your help!!
