Unless you successfully obtain an expunction, it stays on forever.
Another View: When you reach the age of majority (adulthood) in your state your juvenile record is sealed to the public.
In some states, it signifies the most serious of all the Misdemeanor offenses.
As long as you live if you do not file to have it expunged/removed.
It depends on what the person was convicted for. In the state of Alabama, some misdemeanor convictions can be expunged from a person's record. In other cases, it will be part of the person's permanent record. A lawyer should be consulted to see if an expungement is possible.
Your criminal record is ALWAYS your record, unless the offense occurred prior to your 18th birthday.
A misdemeanor in an American court should not be a bother, as long as you are not on probation for it. A common infraction would be if you were a minor in the jurisdiction of the court putting it on your record. If you had a felony, then I would surely be concerned.
Any charge, misdemeanor or felony, committed after you are 18 stays on your record forever, unless it later expunged, in which case it is no longer visible on your PUBLIC record, but law enforcement agencies can always access it. UNLESS a conviction is overturned and you are later found to be innocent.
If you are referring to your drivers license record, it will always remain as part of your permanent drivers record.
It does not depend on the state, it depends on the school.
Unless it was committed prior to your 18th birthday, it will always remain a part of your criminal record.
If it was commited after your 18th birthday it will always be a permanent part of your criminal history record.
Unless it occurred before you turned 18, it will become a permanent part of your criminal history record.
If it occurred after your 18th birthday, it will remain a permanent part of your criminal history record.
