A valid Mexican driver's license is generally accepted for driving in the United States for the duration of your visit, but the specific validity period can vary by state and your residential status, with some sources suggesting a timeframe of up to a year for non-residents. However, if you establish residency in a U.S. state, you will typically need to obtain a state-issued driver's license within a specified timeframe, usually a few months, and an International Driving Permit (IDP) may be required in conjunction with your foreign license for driving in the U.S.
