Will I be able to obtain a security clearance? 5 years ago got a DUI- PBJ (probation before judgment) also got charged with (hit and run) fleeing parked car with damage but got nolle pros on that charge. Both happened on same night incident.
No one can tell you definitively whether or not you’ll get a clearance. One question I would have that may or may not make a difference is whether those two charges were result of one incident or if they are two separate charges from two separate incidents, which would then point more towards a pattern of behavior rather than an isolated event that you haven’t repeated etc.
Time since incident is also a facto, and you indicate five years at least from the DUI so that’s in your favor to some extent. As I said, no one can say for sure, but I would think that unless the parked car incident was recent, you certainly aren’t automatically excluded from eligibility.
