If you were arrested but not charged, had your case dismissed or went to jury trial, and was acquitted, you want to consider pursuing a finding a factual innocence. The fact that you were charged may still show up on a criminal background check if an employer or school performed one. To fully get past the charge, it may be worthwhile to consider asking a court to completely clear it from your record with help from an expungement attorney.
Only Juvenile Records are Sealed
For the most part, only juvenile records are sealed after a case is concluded. In other words, if you committed a crime after you turned 18, it becomes a public record, and can be discovered by prospective employers during the job application process or by anyone else interested in working with you. While some may be forgiving of your past mistake or be interested in the context of why you were charged, others may simply reject your application or assume that you are not trustworthy enough to associate with.
