Visa Information

General Information

A visitor visa allows you to stay in Mexico for a period of up to 180 days if carrying out any unpaid activities. This includes tourism, volunteering, studying courses shorter than 6 months, transit and attending business meetings, among others, as long as you are absolutely sure that no monetary earnings will be derived from your activities in Mexico. All visas are processed at the Mexican Embassy at your country. The physical presence of the applicant at the Embassy is an absolute requirement. Attendees should check if they require a visa to enter The United State of Mexico on the website of Minister of Foreign Affairs of Mexico.

Do I need a Visitor Visa?

Citizens of the countries listed here do not require a Mexican visitor visa to enter Mexico for business, tourism, short studies (under 6 months) or transit.

If you have a valid multiple entry US visa, you can use it to enter Mexico for up to 180 days without a Mexican Visitor Visa, as long as your US visa is valid during your stay and you do not work while in Mexico.
