St. Maarten is only welcoming passengers from neighboring islands starting July 1st so Americans from the USA and Canadians can not go to SXM yet. The travel entry requirements are for those coming from other Caribbean islands.
The travel advisory is subject to change as time progresses. For passengers allowed to travel to SXM it is recommended to take a Covid19 test within 72 hours prior to boarding and have proof on arrival. There will be thermal screening and temperature checks upon arrival. Random Covid19 testing will be done for arriving passengers at their expense.
