The Mexico Business Land Card is required for travelers entering Mexico by land for short-term business purposes such as meetings, negotiations, trade visits, or conferences. Issued under the FMM (Forma Migratoria Múltiple), this card allows a temporary stay of up to 180 days, depending on immigration approval. It must be obtained and stamped at the land border immigration office before continuing travel. The Business Land Card does not permit paid employment or long-term work in Mexico. Travelers must keep the card safe during their stay and return it when exiting the country to avoid fines or complications.
