Visa
the Central American Single Visa (Visa Única Centroamericana) was implemented by the CA-4 agreement between Guatemala, El Salvador, Honduras, and Nicaragua. It is required for citizens of all other countries, eliminating the need for separate entry visas for each of the countries. Persons entering the region on Type "B" visas can enter the area through any Port of Entry. Persons entering on Type "C" visas (issued through prior consultation with the Ministry of Foreign Affairs) must enter through a Port of Entry in the country that issued the visa. Once a person has been admitted, they may travel onto any of the other countries and are allowed to stay through the date authorized at the original Port of Entry.
