"Permits to Establish a Business:
As an Aruban you do not need a permit to establish a business in Aruba, when it concerns a sole proprietorship. You still need to register your business in the Commercial Register at the Chamber.If you are not an Aruban born Dutch national, you always need a permit to establish a business. Whether you will receive a permit depends on what sort of business you intend to start. The main criteria are if the business provides enlargement of the economic basis and if it is capital intensive."
