The Caribbean citizenship-by-investment programmes have been through more change in the past five years than in the preceding two decades. EU pressure, OECD scrutiny, UK visa access reviews, and the fallout from specific misuse cases have pushed all four major programmes — St. Kitts and Nevis, Grenada, Antigua and Barbuda, and Dominica — through substantial reform processes. The programmes that exist in 2026 are meaningfully different from those of 2019, and the differences matter for applicants.
Here is the current landscape, programme by programme, followed by a comparative assessment of which suits which type of applicant.
St. Kitts and Nevis
St. Kitts runs the world's oldest citizenship-by-investment programme, established in 1984. It has historically been the benchmark against which other CBI programmes are measured — and its reform process has been the most thorough. The Sustainable Island State Contribution (SISC), introduced in 2023, replaced the Sugar Industry Diversification Foundation as the primary donation vehicle.
Investment options and costs:
- SISC donation: USD $250,000 for a single applicant; $300,000 for a family of four
- Approved real estate investment: minimum $400,000 (must be held for 7 years)
- Government fees and due diligence: approximately $10,000-$18,000 per adult applicant additional
Processing time: 45-60 days via the Accelerated Application Process (AAP), which adds a $25,000 premium but significantly compresses timelines. Standard processing: 3-4 months.
Visa-free access: 157 countries including the Schengen zone (30 days visa-free), the United Kingdom (6 months visa-free), and access to most of the Caribbean Community (CARICOM). Note: UK visa-free access is actively reviewed by the Home Office and should not be assumed to be permanent.
Best for: Applicants who want the most established, most recognised CBI passport with the longest track record. The premium reflects the programme's credibility.
Grenada
Grenada's programme has one feature that no other Caribbean CBI offers: Grenadian citizens are eligible to apply for US E-2 Treaty Investor visas. This makes Grenadian citizenship uniquely valuable for applicants who are not US citizens or permanent residents but who have businesses or investment interests in the United States. The E-2 visa allows a treaty investor to enter and work in the US in connection with a qualifying investment, and it is renewable indefinitely.
Investment options and costs:
- National Transformation Fund donation: USD $235,000 for a single applicant; $270,000 for a family of four
- Approved real estate investment: minimum $270,000 (shared ownership) or $350,000 (direct ownership), held for 5 years
- Government fees and due diligence: approximately $8,000-$15,000 per adult additional
Processing time: 4-6 months standard; no expedited process comparable to St. Kitts AAP.
Visa-free access: 147 countries including Schengen and the UK.
Best for: Applicants for whom US E-2 eligibility is the primary driver. This is a meaningful competitive advantage and the single most compelling feature in the Caribbean CBI space for the right applicant profile.
Antigua and Barbuda
Antigua's programme is the one most frequently described as "balanced" — not the cheapest, not the most prestigious, but offering a reasonable cost-to-benefit ratio with a competent administration and a genuine two-island destination for buyers considering the real estate route.
Investment options and costs:
- National Development Fund donation: USD $230,000 for a single applicant; $260,000 for a family of four
- Approved real estate investment: minimum $400,000, held for 5 years
- University of the West Indies (UWI) contribution: USD $150,000 for a family of six (with one member attending UWI tuition-free for one year)
- Government fees and due diligence: approximately $8,000-$14,000 per adult additional
Processing time: 3-5 months.
Visa-free access: 152 countries including Schengen and UK (with the same caveat about UK access as noted for St. Kitts).
Best for: Families, particularly those with children approaching university age who might consider the UWI option. Also attractive for buyers who want a Caribbean real estate asset in a genuinely beautiful, well-developed two-island nation.
Dominica
Dominica runs the most price-competitive programme in the Caribbean. The Commonwealth of Dominica — not to be confused with the Dominican Republic — is a small island in the Lesser Antilles known for rainforest, eco-tourism, and, more recently, its aggressive post-Hurricane Maria reconstruction programme that CBI funds have helped finance.
Investment options and costs:
- Economic Diversification Fund donation: USD $200,000 for a single applicant; $250,000 for a family of four
- Approved real estate investment: minimum $200,000 (shared) or $400,000 (direct)
- Government fees and due diligence: approximately $7,500-$12,000 per adult additional
Processing time: 4-6 months.
Visa-free access: 144 countries including Schengen. UK access has been more restricted than for St. Kitts and Grenada — verify current status.
Best for: Cost-sensitive applicants for whom Schengen access is the primary requirement. Dominica's programme is the most accessible entry point into Caribbean CBI and remains competitive despite the broader market's cost inflation.
The due diligence reality
All four programmes now require multi-source background checks from authorised due diligence agencies, mandatory source-of-funds documentation, and — for most programmes — a formal interview or declaration process that was not required three years ago. The increased rigour has compressed the window of acceptance: applicants with complex corporate structures, PEP (Politically Exposed Person) status, or prior legal matters in any jurisdiction face a more detailed review process and should engage experienced licensed agents from the outset.
The cost of professional representation — a licensed agent or law firm specialising in Caribbean CBI — typically runs $10,000-$25,000 on top of the programme costs. This is not optional for complex cases and is strongly recommended for straightforward ones. The agent provides access to government relationships, document processing expertise, and quality control that significantly reduces the risk of avoidable errors that delay or jeopardise applications.
