A criminal record in the United States stays on record for various periods depending on your state, the crime you committed, and whether it's a misdemeanor or felony.
For example, if you’re doing a background check and screening in Florida, note that misdemeanors last five years.
Additionally, most felonies here last seven years except for murder, which remains on record for life. In North Carolina, nonviolent misdemeanors stay on record for five years.
Then there’s Alabama, where you can petition the court to exempt you from any crimes committed when you were under 18 years old.
