Dutch citizens and US citizens
European Dutch citizens, Dutch citizens from Curaçao, St. Maarten and Aruba and US citizens may freely enter Bonaire, St. Eustatius and Saba for up to six months every twelve months. If these Dutch citizens or US citizens want to work, they may work for a maximum of three months without a declaration of admittance by law.
Aliens can freely enter Bonaire, St. Eustatius and Saba for up to three months every six months. This means that no residence permit is required for that period. However, you must meet certain conditions, such as being able to show proof of return and a passport that is valid for your entire visit. The three-month period may be shortened by the officials at the border (KMar) depending on the purpose of your visit and your means of existence.
In certain situations, aliens do require visas. For general questions about issuance of Caribbean visas (tourist or short stay for Aruba, Curaçao, St. Maarten and for the Caribbean Netherlands (Bonaire, St. Eustatius and Saba)) you can contact the embassy or consulate of the Kingdom of the Netherlands in your country.
