Visa & Entry

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.

For land crossings within the border zone, a Border Crossing Card (BCC) is an alternative. The BCC costs USD 185 and is valid for 10 years. 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.

The Tren Maya (Maya Train) opened a station at CUN Airport (Terminal 4), connecting to the broader Yucatán rail network. Taxis from the Hotel Zone (Zona Hotelera) cost MXN 350–550 (USD $17–28) depending on the zone.Authorized taxis from the airport are sold by ticket inside the terminal; agree on the fare before leaving the building to avoid inflated street prices.
