Mexican passport holders need a B1/B2 visa to enter the United States. The visa is obtained through a US embassy or consulate and requires an in-person interview. B1/B2 visas are typically issued for 10 years with stays of up to 6 months per entry.

It allows entry up to 25 miles from the border in Texas and California, or 55 miles in New Mexico and Arizona. Travel by air or beyond the border zone requires a full B1/B2 visa with a valid passport.
