The ETIAS visa waiver for Mexicans will allow travelers to enter all Schengen Area nations without a visa.
The Schengen zone is formed of almost all European Union countries. Ireland is the only EU country which is not part of this borderless travel area.
There are also some non-EU countries which are members: Iceland, Liechtenstein, Norway, and Switzerland, and 3 microstates: Monaco, San Marino, and Vatican City.
Schengen candidates who are currently in the process of becoming members will also be included in the ETIAS program, even if they are still not official member states by November 2023. These countries are Bulgaria, Croatia, Cyprus, and Romania.
The Schengen agreement states that all contributing nations share a single external border. You will only need 1 travel permit to visit all Schengen countries.
Below you can find the list of the countries you can visit with an ETIAS visa waiver for Mexican nationals.
