Obtaining an Antigua & Barbuda passport is one of the most cost-effective options when considering second residency across Caribbean nations through its Citizenship By Investment Program (CIP). Through this program, an economic contribution must be made either via investing in pre-approved real estate projects or donating to the National Development Fund (NDF). This initial entry requirement begins at only USD 100,000 for a single applicant and USD 150k plus fees for a family of up to four people. In contrast, other islands such as St Kitts & Nevis require minimum investments starting from USD 200k+.
