Two countries, St Lucia and Dominica, offer the cheapest way to obtain Caribbean citizenship for those applying as a single person: to make a donation of $100,000 to the national development fund of the country. If you are applying with a family, then the cheapest Caribbean citizenship program is Antigua and Barbuda.

As of 2026, the most affordable paths to Caribbean citizenship by investment (CBI) are generally found in Dominica and Antigua and Barbuda. Both nations typically offer a "National Development Fund" donation option that starts at approximately $200,000 for a single applicant. This is a significant increase from years prior, following a regional agreement to standardize minimum pricing to maintain program integrity and security. While Dominica is often cited as the most "budget-friendly" for individuals, Antigua and Barbuda is frequently the cheapest option for families, as their donation tier of $230,000 can cover a family of four, making the "per person" cost much lower. Beyond the initial donation, you must also factor in government processing fees, due diligence costs, and legal fees, which can add another $20,000 to $30,000 to the total. These passports provide valuable benefits, including visa-free travel to over 140 countries and potential tax advantages, making them a popular choice for global entrepreneurs seeking a "Plan B" residency.
