How do I change my name (married in August) and renew my license (expired in April) through the mail? I am unable to get an appointment till Feb or March.

If you don't have access to the internet, you should be able to pick up the forms from the DMV. Depending on your location. I know the Rome DMV has them outside during business hours. You can fill out the forms and include the necessary documents copies and all and mail it in.

You can got a new license by doing it online
