6. St. Kitts and Nevis
St. Kitts and Nevis is practically on every list of the top 7 easiest countries to get dual citizenship. Like Antigua and Barbuda, this Caribbean paradise allows for citizenship-by-investment – the longest of its kind in the whole world as it has been around since the 80s. At St. Kitts and Nevis, one of the most inexpensive programs is a $250,000 donation to the Sugar Industry Foundation of the nation. This opportunity is open to everyone except for citizens of Afghanistan and Iraq regardless of where the applicants are currently residing.
