New entry as of November 15, 2021
El Salvador has now joined Mexico in being the second country in the WORLD in late 2021 to have no entry requirements or vaccine passports.
El Salvador originally reopened in September 2020 but was requiring all arrivals to bring proof of a negative PCR test. Then, on April 21, 2021, they also added proof of being fully vaccinated as a way to avoid testing. However, now as of November 15, 2021, all requirements have been dropped.
