People who drive in the U.S. must have a valid driver's license. If you're a foreign visitor, some states require you to have an International Driving Permit (IDP) and a valid license from your own country. Contact the motor vehicle department of each state you will be driving to find out its requirements.
If you intend to get an IDP, you must do so in advance of your travel:
The United States does not issue IDPs to foreign visitors. To get an IDP, contact the motor vehicle department of the country that issued your driver's license.
If you want to rent a car, you may need both your license and an IDP. Find out the rental company's policies and other requirements in advance.
Beware of international driver's license scams.
The residency requirement for obtaining a U.S. driver's license is different in each state:
If you are eligible to apply for a driver's license, you must get a driver's license from the state where you live.
Check the requirements and find out how to apply by contacting your state's department of motor vehicles.
A U.S. driver's license allows you to drive anywhere in the U.S. It is your responsibility to know and obey the laws of the state where you are driving.
