Comparing Turkey CBI with Caribbean CBI: Investment thresholds, passports, and processing times

Comparing Turkey CBI and Caribbean CBI is a mandatory analysis for every Vietnamese investor considering a Citizenship by Investment (CBI) programme. These two market groups represent two completely different approaches: Turkish citizenship by investment focuses on strategic Eurasian real estate with a US$400,000 threshold, while the five Caribbean CBI programmes (Saint Kitts and Nevis, Grenada, Dominica, Saint Lucia, and Antigua and Barbuda) offer flexible donation options from US$200,000 to US$250,000.

The article provides a detailed analysis of the comparison axes: investment thresholds and options, passport strength, application processing time, the United States E-2 route, actual residency requirements, due diligence, and the level of suitability for each investor group. All data is aggregated from government Citizenship by Investment Units in 2026.

Overview of the two programme groups

Before delving into specific criteria, it is necessary to clearly understand the fundamental differences between the two programme groups.

Turkey CBI is designed around real estate investment with a minimum threshold of US$400,000 (accounting for over 90% of actual applications), alongside options for US$500,000 in government bonds, US$500,000 in bank deposits, and an investment creating 50 jobs. Characteristic: investors hold real assets and, conversely, can resell after 3 years to recover capital (in full or in part).

Caribbean CBI is designed around non-refundable donations to a national development fund. Only a small portion of applications choose the real estate option (with a threshold US$70,000 to US$130,000 higher than the donation). Characteristic: simple donation, short duration, lower threshold, but no asset for capital recovery.

According to Saint Kitts and Nevis Citizenship by Investment Unit and Investment Migration Agency Grenada, the five Caribbean programmes signed a Memorandum of Agreement in 2024 committing to maintain a unified investment floor and ceiling, ensuring healthy competition between the nations.

Comparing Turkey and Caribbean CBI by investment threshold

This is the most distinct criterion, directly affecting the investment decisions of Vietnamese investors.

Donation option (Caribbean only)

The Caribbean offers a non-refundable donation option to the government fund, which is the simplest and most popular method. The minimum for the main applicant (or a family of up to 4, depending on the programme):

• Dominica: US$200,000 for a single applicant, US$250,000 for a family of 4
• Antigua and Barbuda: US$230,000 for a family of 4 (NDF) or UWI Fund for larger families
• Grenada: US$235,000 for a single applicant or a family of 4 (NTF)
• Saint Lucia: US$240,000 for an applicant (NEF), plus additional family members
• Saint Kitts and Nevis: US$250,000 for an applicant (SISC) or Public Benefit Option

Turkey has no donation option. The entire US$400,000 capital is invested in real estate and must be held for at least 3 years before being permitted for sale.

Real estate option

This is a criterion where Turkey has a relative advantage:

• Turkey: US$400,000 (held for 3 years) — details in the article investing in US$400,000 Turkish CBI real estate
• Saint Kitts and Nevis: US$325,000 (developer real estate, held for 7 years) or US$600,000 (private real estate)
• Grenada: US$270,000 (held for 5 years)
• Dominica: US$200,000 (held for 3 years for this application or 5 years for the next)
• Saint Lucia: US$300,000 (held for 5 years)
• Antigua and Barbuda: US$300,000 (held for 5 years)

Although the Caribbean threshold is lower, Caribbean properties are usually resort projects with limited liquidity and appreciation potential. Turkish real estate has a large secondary market, many choices of types and locations, and is supported by the world’s 17th largest economy.

Comparing Turkey and Caribbean CBI regarding passport strength

This is a criterion where the Caribbean clearly leads in the comparison of Turkey and Caribbean CBI.

Number of visa-free countries

According to the 2026 passport rankings:

• Saint Kitts and Nevis: 150+ countries, including the Schengen area, the UK, Singapore, and Hong Kong
• Antigua and Barbuda: ~151 countries, including Schengen and the UK
• Saint Lucia: ~147 countries, including Schengen and the UK
• Grenada: ~148 countries, including Schengen, the UK, and notably China
• Dominica: ~145 countries, including Schengen (note: as of 2024, a UK visa is required)
• Turkey: ~110 countries, excluding Schengen, the UK, and the United States

The biggest difference is that the Caribbean has 90/180-day visa-free Schengen access, while Turkey still requires a Schengen visa for its citizens. For Vietnamese investors with a need to travel to Europe frequently, this is a deciding factor.

Specific residency rights

Caribbean passports (especially Saint Kitts, Antigua, and Saint Lucia) all grant residency and work rights in Commonwealth nations, including certain privileges in the UK and 53 other member countries.

A Turkish passport does not have special residency rights, but it allows visa-free entry into Japan, South Korea, and several other Asian countries.

Comparing Turkey and Caribbean CBI regarding the United States E-2 route

This is the most important strategic difference in the comparison of Turkey and Caribbean CBI. The United States E-2 visa is an investment work visa allowing citizens of countries with trade treaties with the United States to live and conduct business in the United States with a minimum investment of approximately US$100,000 to US$200,000 in a United States business. The visa has a 5-year term, renewable indefinitely as long as the business remains operational.

Turkey: direct E-2 route

Turkey has an E-2 treaty with the United States. After receiving Turkish citizenship, investors can apply for an E-2 visa immediately at the United States Embassy in Ankara or the Consulate General in Istanbul. This is the shortest route from investment capital to United States residency through CBI.

Caribbean: only Grenada has E-2

Of the 5 Caribbean programmes, only Grenada has an E-2 treaty with the United States. The other four programmes (Saint Kitts, Dominica, Saint Lucia, and Antigua) do not have this route.

The difference: a Grenada passport provides immediate eligibility for the E-2 visa; a Türkiye passport offers the same. Investors intending to live or conduct business in the United States should limit their options to Grenada or Türkiye. Details on the E-2 visa from Türkiye are presented in the article Türkiye passport for visa-free travel and USA E-2.

Comparison of total E-2 costs from both programmes

Total cost from Türkiye: US$400,000 in real estate (resellable after 3 years) + E-2 business investment costs (US$100,000 to US$200,000) = US$500,000 to US$600,000 in working capital.

Total cost from Grenada: US$235,000 donation (non-refundable) or US$270,000 in real estate + E-2 costs = US$335,000 to US$470,000. Costs are lower, but the Grenada donation is not recoverable.

Processing time

This criterion is relatively similar between the two groups:

• Saint Kitts and Nevis: 3-6 months (fastest in the Caribbean)
• Dominica: 3-6 months
• Grenada: 6-8 months
• Antigua and Barbuda: 4-6 months
• Saint Lucia: 4-12 months (may be extended for complex applications)
• Türkiye: 3-6 months from the completion of the real estate transaction

The total time from initiation to receiving a Türkiye passport is usually longer because it requires an additional 1-2 months for preparation (opening a bank account, registering for a tax ID, SPK valuation, transferring capital, and purchasing real estate). Details in the article 6-step Turkish CBI process.

Actual residency requirements

Both programme groups are among the most favourable in the world for this criterion.

Caribbean CBI programmes do not require physical residence before or after receiving citizenship. Some programmes have proposed a short-term visit requirement of 1-5 days starting from 2026, though this is not yet official law.

Türkiye does not require continuous residence, but applicants must be present in Türkiye for a few short visits to complete mandatory procedures: opening a bank account, registering the Tapu at the land registry office, and providing biometric data when receiving citizenship. Total physical presence is approximately 5-10 days, usually split into 2-3 trips.

Due diligence and reputation level

Both programme groups apply strict due diligence processes according to international standards.

The Caribbean coordinates with independent due diligence firms in Europe, the UK, and the United States to conduct comprehensive background checks. Due diligence fees range from US$7,500 to US$10,000 for the main applicant, and US$5,000 to US$7,500 for each dependent over 16 years old. Since 2024, Saint Kitts and Nevis has mandated in-person interviews for the main applicant and dependents over 16 years old.

Türkiye conducts due diligence through multiple government agencies: the Directorate General of Migration Management, the Ministry of Interior, and the General Directorate of Population and Citizenship Affairs. The process is less transparent than the Caribbean, but the approval rate is higher (fewer rejections) due to the clear capital investment structure through the banking system and the DAB.

Who should choose Turkey, who should choose the Caribbean

Based on the analyses above, we can categorise investors as follows:

Suitable for Türkiye CBI

• Investors with a budget of US$400,000 to US$600,000 who wish to hold assets in the form of liquid real estate
• Investors planning for a USA E-2 visa within the next 5-10 years
• Investors with a need to live/conduct business in Asia, the Middle East, or who wish to combine holidays on the Aegean and Mediterranean coasts
• Large families (5 people or more) who want a second home for actual use

Suitable for Caribbean CBI

• Investors with a budget of US$200,000 to US$300,000 who prioritise simplicity and speed
• Investors who need to travel frequently to Europe (Schengen), the UK, and Singapore
• Investors who want a backup citizenship (Plan B) without needing to actually use the investment property
• Prioritise Grenada if planning for a USA E-2 visa with a lower budget than Türkiye
• Investors from countries where obtaining a Chinese visa is difficult (choose Grenada or Dominica)

Combining both

Some investors with a large budget (US$600,000 or more) and goals for diversification may consider investing in both programmes to maximise entry rights and residence options.

Summary

Comparing Türkiye and Caribbean CBI shows that no programme is absolutely “better”; it depends on the specific goals of each investor. Türkiye excels in terms of recoverable assets, direct E-2 thresholds, and the long-term economic potential of the property. The Caribbean excels in low investment thresholds, fast processing speeds, the strength of the Schengen passport, and the simplicity of the application.

Vietnamese investors should take four steps: (1) define the primary goal (Schengen travel, USA pathway, second home, or diversification); (2) compare the actual budget with the total cost of each programme; (3) assess the willingness to lock up capital for 3-7 years versus a non-refundable donation; (4) consult an expert to choose the most suitable programme.
