MANDATORY APPLICATION
Due to the COVID-19 pandemic Sint Maarten has established a mandatory Electronic Health Authorization System (EHAS) for every visitor whether arriving by air, boat or in transit. Without the health authorization, entry into the country will be denied by the immigration authorities. Visitors are encouraged “to complete this process as soon as they comply with the vaccination requirements” or have received their negative rt-PCR or antigen test result.
