I Had a Felony Conviction as a Juvenile. Can I Enlist?
Question: I had a felony conviction as a juvenile. Am I still eligible to join?
Criminal Offenses which may preclude enlisting (or a commission) in the military can be found in our article about Enlistment Qualifications.
There's no such thing as a "sealed" or "expunged" record, as far as the military is concerned. The military requires (under federal law) that such records be revealed on enlistment and security clearance paperwork. Failure to do so is a felony. For more information, see the article, I Cannot Tell a Lie.
