You should apply for your Curacao Immigration and Locator Card before you travel. The application process is simple and your card will facilitate your stay in Curacao. However, there are many other ways to travel to Curacao. Dutch is also the main language in Curacao. However, a small number of people can also speak English. Most foreigners who reside in Curacao are from Europe, Spain, Germany and Greece. The island of Curacao is a Dutch protectorate, and so the government maintains sole authority over activities in Curacao.
