Any traveler from the U.S. or Canada must also possess a valid passport and a return ticket to enter St. Martin. If you do not have a return ticket, you must present a ticket for further travel plans to another destination.
Visas are not required to EU nationals, but they must present a valid passport. French citizens entering on the french side of the island may present an official French identity card or French residency card (carte de séjour) upon arrival.
