Yes, you can absolutely travel to Mexico in 2026 with a passport that expires in 6 months. Unlike many European or Asian countries that strictly enforce a "six-month rule," Mexico’s official entry policy is that your passport must only be valid for the duration of your intended stay. However, the Mexican Embassy often recommends having at least 180 days (6 months) of validity because 180 days is the maximum duration a tourist can stay in the country. If you have exactly 6 months remaining, you are in a safe zone. For 2026 travelers, a "high-value" tip is to double-check the requirements of any transit countries; if you have a layover in a country like Panama or the US on your way to Mexico, those specific nations might require 6 months of validity even if Mexico itself does not.
