Caribbean CBI comparison of St Kitts, Antigua, Grenada and Dominica in 2026: 2026 costs, passport ranks, the E-2 route and US visa changes decoded.
The four programmes in this Caribbean CBI comparison — St Kitts vs Antigua vs Grenada vs Dominica — are often treated as interchangeable. They are not. In 2026, the gap between them is no longer about headline price; it is about US treaty access, family economics, passport strength and a wave of new compliance rules. At VisaTier, we don't sell a passport — we build a strategy around the right fit. This guide sets out the real differences, verified against current programme and index data.
The Caribbean "big four" donation routes now sit within roughly US$35,000 of each other at the entry point. That makes price a poor sole deciding factor. What separates them is structure: who counts as a dependant, whether you recover capital, which passport opens which door, and how each government has responded to international pressure.
A passport is only as valuable as the doors it opens on the day you need it — not the day you bought it.

The single biggest 2026 development is regulatory.
The National Assembly passed the Eastern Caribbean Citizenship by Investment Regulatory Authority Bill 2025, establishing a unified regional regulator covering CBI programmes in Antigua and Barbuda, Dominica, Grenada, Saint Lucia, and St. Kitts and Nevis, intended to harmonise due diligence standards and governance across the Caribbean CBI market.
This is precisely why robust vetting matters; we explore the logic in our analysis of why strict due diligence protects investors.
The figures below are the minimum qualifying investment plus an indicative all-in cost for a single applicant. Total estimated cost includes due diligence, government, processing and passport fees, and will rise with family size and the chosen route.
| Programme | Min. donation (single) | Real estate route | Passport (Henley 2026) | Total est. cost (single applicant) |
|---|---|---|---|---|
| St Kitts & Nevis | US$250,000 (SISC/PBO) | US$325,000; held 7 years | 23rd; 155 destinations | ~US$275,000–300,000 |
| Antigua & Barbuda | US$230,000 (NDF) | US$300,000; held 5 years | 24th; 154 destinations | ~US$255,000–290,000 |
| Grenada | US$235,000 (NTF) | US$270,000; held 5 years | 27th; 147 destinations | ~US$260,000–295,000 |
| Dominica | US$200,000 (EDF) | US$200,000; held 3–5 years | 29th; 145 destinations | ~US$225,000–260,000 |

For Antigua's National Development Fund, the minimum contribution for a family of up to four is US$230,000, with an additional US$15,000 per person for larger families.
Antigua's structure is unusually family-friendly:
families of six or more can use a US$260,000 donation to a higher-education institution, with processing fees included — the most cost-effective route for large families.
Dominica's single-applicant entry is lower, but
the family-of-four EDF contribution is US$250,000 plus government fees.
The "cheapest" programme therefore depends entirely on who is on the application — a point we make repeatedly in our work on the strongest family golden visa and citizenship routes.
On raw mobility, St Kitts leads.
Per the Henley Passport Index 2026, Saint Kitts and Nevis ranks 23rd with 155 destinations, followed by Antigua and Barbuda at 24th with 154, Grenada at 27th with 147, and Dominica at 29th with 145.
All four reach the full Schengen Area. However, a critical caveat applies across the board.
For Dominica, the United Kingdom revoked visa-free access on 19 July 2023, with a UK visitor visa now required; Ireland followed in March 2024.
More broadly,
the Henley number is a useful proxy but an incomplete measure of passport power, because access is most valuable when it includes major economic centres — the US, EU, UK, Japan, China and Gulf states.
As Muzaffar Saydiganiev, Managing Director at VisaTier and a licensed investment-migration adviser, notes: in our casework, clients consistently overvalue the headline destination count and undervalue which specific doors — the US and UK in particular — actually open.
This is the cleanest differentiator in the entire comparison.
Grenada is the only Caribbean citizenship-by-investment programme that holds an E-2 Investor Visa Treaty with the USA; Grenada has held that treaty since 1989, allowing Grenadian passport holders to apply for long-term investor visas to establish and operate businesses in the United States — a benefit unavailable to holders of other Caribbean CBI passports.
The nuance matters.
Citizens become eligible to apply for the E-2 visa after being domiciled in Grenada for a continuous period of three years.
If US business presence is your objective, only one of these four programmes is relevant — a comparison we examine in depth in our piece on Grenada and Dominica for the US E-2 visa.
Recent US policy has tightened sharply.
For Antigua and Barbuda, entry to the USA with immigrant and non-immigrant B-1, B-2, B-1/B-2, F, M, and J visas was suspended for citizens from 1 January 2026.
Dominica is similarly affected:
the USA suspended entry for Dominica citizens on B-1, B-2, B-1/B-2, F, M and J visas in December 2025.
Any HNW client relying on a Caribbean passport for US visitor access must verify their current position before applying.
On tax, the four are broadly aligned and genuinely attractive for non-residents.
Antigua and Barbuda levies no personal income, wealth, inheritance or capital-gains taxes.
Critically, though,
citizenship alone does not create tax residency; you must spend 183 days a year in the country to be considered a tax resident.
For Dominica,
there are no taxes on foreign-sourced income, capital gains, inheritance or net wealth for residents or citizens who are not ordinarily resident in Dominica.
A second passport changes mobility, not automatically your tax home — a distinction we stress in our guidance on tax residency planning for entrepreneurs.
Compliance is where 2026 bites hardest.
St Kitts launched its National Biometric Enrolment and Passport Modernisation Programme on 14 April 2026 — a mandatory update for all CBI citizens with a hard deadline of 31 July 2027, after which non-compliant passports are deactivated from 1 August 2027.
Antigua, meanwhile, retains a physical-tie rule:
new citizens must reside in Antigua & Barbuda for a minimum of five days within the first five years after citizenship is granted.
St Kitts, Grenada and Dominica impose no such current visit requirement.
There is no universal winner — only the right fit:
In February 2026, the United States formally rescinded its 2014 FinCEN advisory concerning the programme, recognising comprehensive reforms to its governance and due diligence framework.
This is exactly the kind of trade-off our advisers map before any application — the broader philosophy is set out in our guide to multiple citizenships as a strategic asset.
Price is the last question we ask, not the first. Our advisers map family structure, US access, tax position and timeline before recommending a single jurisdiction — so you fund the right citizenship, not the cheapest one.
