7. Antigua and Barbuda
These twin islands offer some of the easiest dual citizenship requirements not only in the Caribbean but practically in the Americas. Like most every country on this list of the top 7 easiest countries to get dual citizenship, Antigua and Barbuda offer citizenship-by-investment programs. In Antigua and Barbuda, the most inexpensive type is the $250,000 donation to their National Development Foundation and staying in the country for 35 consecutive days and accumulated stay of 5 years.
