Mexico Visa
Visit the Mexican National Institute of Migration’s (Instituto Nacional de Migración, INM) website (Spanish only) or the Embassy of Mexico in Washington, D.C. for the most current entry, exit, and visa requirements.
If you enter by land and plan to travel further than 25 kilometers into Mexico, you must stop at an INM office at the port of entry to obtain an entry permit (Forma Migratoria Multiple – FMM), even if not explicitly directed to do so by Mexican officials. You will likely be asked to present this form at immigration checkpoints on your route of travel. You must present a valid passport in order to receive the entry permit. For more information, visit the INM website (Spanish only). If you enter by sea, review the Mexican boating permit requirements prior to travel or contact the Embassy of Mexico in Washington, D.C., for more information.
U.S. citizens should be aware that Mexican law permits Mexican immigration authorities to deny foreigners entry into Mexico if they have been charged with or convicted of a serious crime in Mexico or elsewhere.
