Good day, does anyone know how I can cross to Tijuana Tijuana if my sky is from Tuxtla Gutiérrez? Do they ask for documentation?

If you want to cross into the United States through Tijuana (regardless of which Mexico City your flight comes from), you have to bring a Passport and Valid Visa, in addition to paying the CBX (Cross Border Xpress) crossing, which is around $750 Mexican pesos. ($36) If you are also going to exceed 25 miles (40 km) from the border into the country, you will need to pay the I-94 admission form. It is worth it, above the long lines that are made on foot or by car through the sentry box.

How about .. a pleasure to greet you. If your flight is a national one, you do not need anything other than your official identification (INE or passport for example)
