You are eligible to convert a provisional license by mail provided you do not have temporary lawful status in the United States, your social security number is successfully reverified, there are no compliance requirements pending in another jurisdiction, and the Real ID supporting documents that were presented are still valid when the provisional license was issued after May 1, 2014.
To convert your provisional to a full license, you must be at least 17 years old and must have held the provisional license for at least six months.
