~ Residents have until March 22 to return ~

PHILIPSBURG--As of 11:59pm Tuesday, persons who are not residents of St. Maarten are not allowed to enter the country. After Sunday, March 22, no one, not even residents, will be allowed entry to the country.

The more stringent restrictions come as the country tightens its measures to stem the spread of the coronavirus COVID-19, on the heels of the first COVIID-19 case in St. Maarten on Tuesday.
