Key facts
- Travel: Argentina has the widest reach of the programmes open in 2026, about 170 destinations.
- Family: Antigua and Barbuda (per-application pricing) and Dominica (broad dependant rules).
- Cost and speed: Dominica, from US$200,000 and typically 3–4 months.
- Every programme now carries outside risk: EU visa rules, US restrictions or, for Argentina, a court appeal (legal status).
“Best” depends on the job you need the passport to do. A family seeking a European travel document, an entrepreneur planning a US business and a retiree looking for a new home will choose differently. This guide picks a leader for each use case, using official prices and the July 2026 Henley Passport Index. Figures are as of 2 October 2026.

Best for travel: Argentina
Argentina’s passport reaches about 170 destinations, including the Schengen Area (90 days in any 180) and Japan. That is more than any Caribbean passport, and the most among programmes accepting new applicants in 2026. Read the detail on our passport page.
Two caveats. No programme on this list gives visa-free entry to the United States or Canada; Argentina’s return to the US Visa Waiver Program is not yet agreed. And Argentina’s programme rests on DNU 366/2025, which two appeal courts ruled against in June 2026. The government has appealed to the Supreme Court.
Runner-up: St Kitts and Nevis, with 157 destinations and the longest operating record in the industry.
Best for families: Antigua and Barbuda
Antigua’s National Development Fund contribution of US$230,000 is charged per application, not per person, and the programme accepts dependent parents over 55. For a large household that is hard to beat. The trade-off is mobility: since 1 January 2026 Antigua’s nationals face partial US visa restrictions.
Runner-up: Dominica, whose dependant rules include parents and grandparents over 65 and some children up to 30. Argentina is the weakest here on price, because each family member adds US$25,000 to US$100,000. See our family guide.
Best on cost: Dominica
Among established programmes, Dominica’s US$200,000 is the lowest official entry price, and US$250,000 covers a family of four. Cheaper offers exist, from São Tomé and Príncipe and Nauru at US$90,000, but they come with far weaker passports and newer, less proven administration. Our cheapest programmes ranking sets out the full list.
Best for speed: Dominica, then St Kitts
Dominica’s unit reports approval in typically three to four months. St Kitts and Nevis aims to decide within 120 to 180 days of acknowledging a file. Argentina’s decree gives Migraciones 30 business days after the Agency’s report, but the time before that report, and the overall processing time, are not yet published.
Best for a US business: Grenada (with conditions)
Grenada is the only Caribbean programme on the US State Department’s E-2 treaty investor list. Advisers report that citizens by investment must first live in Grenada for three years before they can use it. Türkiye and Argentina are also E-2 treaty countries; how the US will treat Argentina’s investor-citizens is untested. Speak to a US immigration lawyer. Read Argentina vs Dominica and Grenada.
Best for lifestyle: Argentina
If you might actually live in your second country, size and depth matter. Argentina is the world’s eighth-largest country, with 46 million people, 23 provinces plus Buenos Aires, a single time zone (UTC−3) and a full economy. Naturalisation through investment does not by itself make you an Argentine tax resident; the normal residence rules apply.
Türkiye is the other large-country option, and its route lets you keep capital in property. For a European life, citizenship by investment is no longer available: Malta closed its investor route in 2025, and Portugal’s Golden Visa now leads to citizenship only after ten years. See Argentina vs Portugal and Argentina vs Türkiye.
Regional alternatives such as Paraguay, Uruguay and Brazil sell residence, not passports, but may suit people who will move.
Best for durability: no clear winner
Every option carries outside risk in 2026. Regulation (EU) 2025/2441, in force since 30 December 2025, lets the EU suspend visa-free travel for countries that sell citizenship. The Commission has reportedly asked the five Caribbean programmes to end by June 2028. The US restricted visas for Antigua and Dominica nationals from January 2026. Argentina faces a Supreme Court decision on its decree. Read what the Malta ruling teaches.
Who should choose what
- Single applicant or couple, travel first: Argentina, if you accept the legal risk; St Kitts if you do not.
- Large family on a budget: Antigua or Dominica, with the US restrictions understood.
- US business plan: Grenada, if you can meet the residence condition.
- Capital preservation: Türkiye, with independent property valuation.
- A place to live in South America: Argentina, or a residence route in a neighbouring country.
The honest verdict
For mobility, Argentina is the strongest passport on sale in 2026, at a higher price and with a court case pending. For families and budgets, the established Caribbean programmes still offer the best value, but their access to Europe and the US is under more pressure than at any time before. For durability, no programme can promise it.
The sensible approach is to choose by use case, test each programme’s weakest point, and keep a plan B. Compare more on our comparison hub or request a private briefing. This is not legal, tax or investment advice; speak to a qualified adviser.
