The Types of Entry Documents for Mexico depend on nationality, travel purpose, and the intended length of stay. Foreign visitors may need a valid passport together with a Mexican visa, an electronic authorization where applicable, or another qualifying immigration document. Visitors entering as tourists or business travelers without permission to perform paid activities may use the relevant visitor documentation, while temporary and permanent residents require their respective residence documents. Mexico also uses the Multiple Immigration Form (FMM) to document certain visitor stays. Nationals of countries covered by Mexico's visa-exemption arrangements may enter without obtaining a Mexican visa, subject to immigration inspection. Travelers should confirm the exact documentation required before traveling.
