Is a passport required for U.S. citizens to move to Mexico?
Yes. According to the U.S. Department of State Bureau of Consular Affairs, U.S. citizens (including children) must present a valid US passport book or card to enter Mexico – whether moving there or just visiting. If you enter Mexico by air, a passport book is required. If you enter Mexico by land or sea, you can use a passport book or passport card.
