You should apply for your Curacao Immigration and Locator Card before you travel. This application process is fairly simple, and your card will help facilitate your stay in Curacao, though there are of course many other means to travel to Curacao too. In Curacao, Dutch also is the main language (though English is also spoken by a small percentage of citizens). Most foreigners who reside in Curacao are from Europe, Spain, Germany and Greece. Curacao is an island that is part of a Dutch protectorate. Therefore, the government has sole authority over Curacao's activities.
