The Citizenship-by-Investment Unit (CIU) is the Government Authority which handles all matters concerning Citizenship-by-Investment in the Federation of St. Kitts and Nevis.

The Citizenship-by-Investment Program was established in 1984, making it the longest established program of this kind in the world. It has distinguished itself from many other similar programs by rigidly enforced investment requirements and meticulous due diligence procedures. The Government of St. Kitts and Nevis utilizes this program to attract investors of good character to make a substantial contribution to the development of the Federation. These investors are then given the opportunity to apply for citizenship and passport within the strict guidelines of the law and the relevant regulations.
