South Korea to Mexico visa requirements

Visa-free for visitor stays up to 180 days. Mexican immigration sets the actual authorized stay; air arrivals use a stamp/FMMD flow, while land arrivals must handle the FMM. South Korean ordinary passport holders do not need a Mexican visa to enter as visitors without permission to work for tourism, transit, family visits, short non-paid business activity, or other non-remunerated visitor purposes for up to 180 days. Korea MOFA confirms ordinary Korean passports are visa-free for Mexico for a maximum 180-day stay and that Mexico does not issue visas on arrival; Mexico's INM also lists visa-exempt visitors as entering under the visitor-without-remunerated-activities category. The 180 days are a maximum, not an entitlement: the immigration officer records the authorized stay at entry and may ask for return or onward travel, accommodation, itinerary, funds, address, and purpose details. At international airports, INM says travelers do not need to present, fill out, or carry a paper FMM because the record is generated at entry and the stamp or automated-gate receipt carries the stay information; the downloadable FMMD is proof of lawful stay. Land entrants still need to complete or validate the FMM and pay any applicable entry fee. Korean passport holders age 18 or over may be able to use automated tourist gates at selected airports including Mexico City, Cancun, Los Cabos, Puerto Vallarta, Queretaro, and Guadalajara, but residents and student-visa holders should use staffed immigration to avoid being admitted as tourists. There is no Mexican ETA, eVisa, or SAE requirement for Korean ordinary passport holders using the visa-free route.
