Antiguans and Barbadians hoping to gain entry into the United States must be vaccinated as of today. According to a release from the US Embassy in Barbados, as of November 8th all non US citizens and non-immigrant adult air passengers will be required to be fully vaccinated against covid-19, and provide proof of such prior to boarding a plane to the United States.
This applies to all non US citizens over 18 with only limited exemptions. The statement further said that this is in addition to the testing requirement currently in place, which requires travelers to produce a negative test result within three days of travel.
US citizens, lawful permanent residents or the small number of exempted unvaccinated foreign nationals will also be required to test within one day of departure.
