The Caribbean has four primary citizenship by investment programmes that account for the overwhelming majority of global CBI activity: St. Kitts & Nevis, Grenada, Antigua & Barbuda, and Dominica. A fifth programme — St. Lucia — is smaller by volume. Each programme delivers Caribbean citizenship and a second passport, but they differ on investment threshold, processing time, physical presence requirements, passport strength, strategic utility, and exit liquidity on the underlying real estate investment.
This article compares the four primary programmes on the dimensions that matter for investors making a programme selection decision.
The Key Dimensions
Investment Thresholds
Dominica: USD 200,000 minimum in approved real estate (or USD 100,000 non-refundable contribution to the Economic Diversification Fund).
Antigua & Barbuda: USD 200,000 minimum in approved real estate (or USD 100,000 National Development Fund contribution for a family of up to four).
Grenada: USD 220,000 minimum in approved real estate.
St. Kitts & Nevis: USD 250,000 minimum in approved real estate (or USD 125,000 Sustainable Island State Contribution for a single applicant).
Processing Time
All four programmes typically process in 3–6 months. Grenada has historically been slightly slower due to thorough due diligence processes; St. Kitts has an accelerated processing option. Processing times can vary based on application quality and case complexity.
Physical Presence Requirements
Antigua: The applicant must spend at least five days in Antigua during the first five years of citizenship. This is the only Caribbean CBI programme with a minimum presence requirement.
St. Kitts, Grenada, Dominica: No physical presence requirement after citizenship is granted.
Passport Strength (Visa-Free Destinations)
St. Kitts: ~157 destinations
Antigua: ~151 destinations
Grenada: ~146 destinations
Dominica: ~145 destinations
All four provide Schengen Area access (90 days within any 180-day period), UK access, and broad Caribbean and Commonwealth access.
Strategic Differentiators
Grenada: The E-2 Advantage
Grenada’s bilateral investment treaty with the United States makes Grenadian citizens eligible to apply for US E-2 Treaty Investor Visas. No other Caribbean CBI programme provides this. For investors from countries without US E-2 treaties — China, India, Russia, Brazil, and others — this is a structural advantage that justifies the slight premium over Dominica and Antigua.
St. Kitts: Programme Credibility
St. Kitts launched the world’s first CBI programme in 1984 and has the longest track record and the most developed institutional credibility. The St. Kitts passport is widely accepted, and the programme has consistently withstood OECD and EU scrutiny. For investors who prioritise programme stability and passport reputation above cost minimisation, St. Kitts is the benchmark.
Antigua: Family Efficiency
Antigua’s programme pricing is structured efficiently for families: the USD 100,000 National Development Fund contribution covers a family of up to four people (versus per-person contribution structures elsewhere). For families with multiple dependants, Antigua’s total cost can be the most competitive of the four programmes.
Dominica: Cost Efficiency
Dominica is consistently the most cost-efficient Caribbean CBI programme. The non-refundable contribution route (USD 100,000 for a single applicant) is the lowest entry threshold in the Caribbean CBI market. Post-Hurricane Maria reconstruction has positioned Dominica’s approved real estate developments as genuine resort infrastructure investments.
Exit Liquidity: The Dimension Most Marketing Omits
A critical consideration in any real estate-based CBI investment is what happens to the real estate when the investor wants to liquidate. Most CBI programme marketing focuses entirely on the citizenship benefit and glosses over the exit liquidity question.
The honest assessment: approved CBI real estate in Caribbean markets is a category of investment specifically designed to meet government approval criteria. Secondary market liquidity — the ability to sell the property after the minimum holding period to a third-party buyer at or above the original investment price — is limited in most Caribbean CBI markets. The property is a fee for the citizenship programme as much as it is a real estate investment.
Investors who approach Caribbean CBI real estate as a pure citizenship cost (the total investment minus the expected net resale proceeds, discounted to present value) are making a more accurate calculation than those who treat the full investment amount as a recoverable asset.
Some approved developments — in St. Kitts, Grenada, and select Antigua projects — do have meaningful rental management programmes and secondary market activity. Others are more notional. Due diligence on the specific approved project matters as much as programme selection.
The Bottom Line
For investors who need US E-2 access: Grenada is the only viable Caribbean CBI option. For investors who prioritise programme credibility and passport strength: St. Kitts. For families optimising cost: Antigua. For individual investors minimising total outlay: Dominica. The MPH Intelligence Hub covers each of these four markets with market-specific real estate context, including the approved developments that have demonstrable rental performance and secondary market activity.
