Passport by Investment: Caribbean and European Options in 2026 — Costs, Countries, Benefits and Eligibility

Introduction: Can you obtain a second passport through investment?

A second passport can offer international mobility, additional travel options, business opportunities and greater flexibility for families who want to explore life abroad. One route that attracts high-net-worth individuals is Citizenship by Investment (CBI), through which eligible foreign nationals may obtain citizenship after making a qualifying contribution or investment under a country's legal programme.

The Caribbean is one of the best-known regions for citizenship-by-investment programmes. Countries such as Dominica, Antigua and Barbuda, and St. Kitts and Nevis offer qualifying routes starting at hundreds of thousands of US dollars.

Europe offers a different set of opportunities. Türkiye (Turkey) provides a direct citizenship-by-investment route, while Portugal offers a residency-by-investment programme that may eventually lead to citizenship if the applicant meets the applicable nationality requirements.

However, an important distinction must be understood from the beginning:

- Citizenship by investment: A qualifying applicant can apply for citizenship and, after approval, a national passport.

- Residency by investment: An investor receives a residence permit, not an immediate passport. Citizenship may become possible later if the applicant meets the country's legal requirements.

- Permanent residence: A longer-term immigration status that does not automatically make someone a citizen.

This distinction is particularly important when comparing Caribbean citizenship programmes with Portugal's Golden Visa.

This article examines the main options, published investment thresholds, application procedures, potential benefits, risks and considerations for Indian applicants as of October 2026.

1. Caribbean citizenship by investment: An overview

The Caribbean's citizenship-by-investment programmes are designed to attract foreign capital for economic development. Depending on the country and selected investment route, eligible applicants may qualify through a government contribution, approved real estate, or a qualifying business investment.

The headline investment amounts below are in US dollars and exclude any additional government, due-diligence, agent, legal, passport and other applicable fees.

A. Dominica — citizenship through a government contribution or real estate

 Dominica 

From US$200,000

Citizenship by Investment Programme

Dominica offers two main qualifying routes: a contribution to its Economic Diversification Fund (EDF) or investment in approved real estate. The government describes the programme as a way to support national development while providing a route to citizenship for eligible investors. 

Investment options

- Economic Diversification Fund: A non-refundable contribution starting at US$200,000.

- Approved real estate: A qualifying investment starting at US$200,000 in a government-approved project.

The real estate route has a holding period: the property must generally be held for three years, or five years when the subsequent buyer is another citizenship-by-investment applicant.

Dominica Citizenship

Who might consider Dominica?

Investors who want a citizenship programme without committing to long-term residence may find Dominica worth investigating. Applicants must undergo background checks, demonstrate the lawful source of funds and meet the programme's eligibility criteria.

Important: The contribution is not a refundable deposit. Buying property also involves commercial risks, including resale limitations, maintenance costs and the possibility that its value may fall.

B. Antigua and Barbuda — a family-oriented citizenship programme

Antigua and Barbuda

From US$230,000

Citizenship by Investment Programme

The university-fund option is intended for families of six or more. Additional government processing and due-diligence fees may apply, and the precise total depends on the application. 

A notable family requirement

Antigua and Barbuda's programme has a physical-presence requirement: a successful applicant must spend at least five days in the country during the first five calendar years after obtaining citizenship to avoid the risk of deprivation on that ground. This makes it important to distinguish the programme from options that do not impose a comparable minimum visit. 

The Citizenship by Investment Programme

Who might consider it?

Families comparing different qualifying investment routes may find this programme attractive, especially if they want to evaluate the university-fund option or approved property.

C. St. Kitts and Nevis — an established citizenship-by-investment option

St. Kitts and Nevis

From US$250,000

Citizenship Programme

Main investment routes

These figures are qualifying investment amounts, not necessarily the final cost of obtaining citizenship. Additional due-diligence fees and other government charges may apply. 

The government publishes a target of 120–180 days for the initial decision on the SISC route, measured from acknowledgment of the application. This is not a guarantee that every application will be completed within that period. 

Who might consider it?

Applicants who value an established programme and want to compare a non-refundable contribution with property ownership or a public-benefit project may wish to explore this option.

Important Caribbean development: EU travel access is a changing issue

There is a significant policy risk that investors should understand before purchasing Caribbean citizenship.

In July 2026, the government of Antigua and Barbuda reported that the European Commission had requested the phase-out of citizenship-by-investment programmes operated by five Eastern Caribbean states by 1 June 2028. The Commission's position relates to changes in the EU visa-suspension framework. The countries affected include Dominica, Antigua and Barbuda, St. Kitts and Nevis, Grenada and Saint Lucia. 

Government of Antigua and Barbuda

This is a future policy risk, not a statement that all existing visa-free access has already been withdrawn. Investors should check the latest EU rules and the destination country's entry requirements before making a decision.

A passport's visa-free access is a policy benefit that can change; it is not a permanent contractual guarantee.

2. Türkiye (Turkey): Direct citizenship through investment

Türkiye offers a direct citizenship-by-investment route under its exceptional citizenship framework. Unlike Portugal, which offers investment-based residence, qualifying foreign investors in Türkiye may apply for citizenship after completing an eligible investment and satisfying the relevant legal conditions.

Minimum investment routes

The Turkish government's investment guide publishes the following qualifying thresholds.

These are qualifying investment thresholds; legal, valuation, transaction and application expenses may be additional.

How does the Turkish property route work?

The property option is widely discussed because it offers ownership of a real asset rather than a purely non-refundable government contribution.

The general process involves:

1. Selecting qualifying real estate and verifying ownership, title and valuation.

2. Confirming that the property satisfies the investment rules and minimum value.

3. Completing the purchase and the required declaration or resale restriction.

4. Obtaining the relevant investment-compliance documentation.

5. Submitting the citizenship application and supporting documents.

6. Completing the necessary checks and waiting for the competent authorities' decision.

The government specifies a minimum property value of US$400,000 and a restriction on resale for at least three years. A purchase agreement alone does not necessarily establish legal property ownership; registration and proper title verification matter. 

Potential benefits

- A direct route to Turkish citizenship, subject to approval.

- Property ownership or another qualifying investment asset.

- Access to Türkiye for living, business and personal purposes under the rights attached to citizenship.

- The possibility of including eligible family members, subject to applicable rules.

Risks to consider

Real estate prices can fluctuate, resale may take time, and foreign exchange movements can affect the actual cost. Applicants should also assess tax obligations, property title, developer credibility and the difference between Turkish citizenship and access to the EU.

Crucially, a Turkish passport is not an EU passport. Turkish citizenship does not automatically provide the right to live or work in Portugal, Germany or other EU member states.

3. Portugal: Golden Visa and the potential path to citizenship

Portugal is an important option for investors who want a European residence permit and may eventually seek citizenship. Its investment-based residence programme is commonly known as the Golden Visa, officially the Residence Permit for Investment Activity (ARI).

Unlike the Caribbean programmes and Türkiye's qualifying citizenship route, Portugal's Golden Visa does not grant a passport immediately.

Instead, it provides a route to residence, subject to approval, with the possibility of applying for Portuguese citizenship later if the applicant meets the nationality law and all other applicable requirements.

Portugal Golden Visa investment options

Portugal's official immigration agency, AIMA, currently lists qualifying routes including the following.

These are statutory qualifying thresholds, not complete estimates of the cost of obtaining residence. Legal fees, application charges, fund expenses and other costs can increase the total.

Important change: Portugal removed the familiar residential-property purchase route from its Golden Visa qualifying investment options. An investor should not assume that buying an apartment or house for €280,000 or €500,000 qualifies for a new Golden Visa application.

How does the Portugal Golden Visa work?

1. Choose a qualifying investment. This may involve a qualifying investment fund, scientific research, cultural support or an eligible business and job-creation route.

2. Complete due diligence and documentation. The applicant must establish identity, source of funds, criminal-record status and compliance with the chosen investment route.

3. Apply for the residence permit. The application is submitted under Portugal's ARI framework, with the required evidence and fees.

4. Maintain the investment and renew the permit. Applicable minimum-presence, documentation and investment-maintenance conditions must be met.

5. Assess future citizenship eligibility. Citizenship is a separate application. The applicant must satisfy the nationality law in force at the time, including applicable residence, language, criminal-record and other requirements.

Portugal's official guidance describes minimum physical presence under the ARI scheme as seven days during the first year and fourteen days during subsequent two-year periods, subject to the applicable rules. It also identifies a potential route to permanent residence or naturalisation for applicants who qualify. 

Does Portugal guarantee citizenship after five years?

No. Investors should not treat a five-year timeline as an unconditional guarantee.

The investment residence programme and the nationality process are governed by different legal requirements. Citizenship eligibility can depend on the nationality legislation in force, the legally recognised residence period, documentation, language requirements and other conditions. Changes in law or administrative processing can affect the expected timeline.

Before investing, obtain current written advice on how residence time is calculated, whether any legislative amendments affect the application and what happens if the rules change before naturalisation.

Why consider Portugal?

- A European residence permit with rights to live in Portugal under the applicable rules.

- A route to family reunification for eligible family members.

- Schengen travel opportunities under the residence-permit framework.

- A potential long-term path to Portuguese citizenship if the legal requirements are satisfied.

- Investment choices that do not depend on purchasing residential property.

However, the route may take considerably longer than direct citizenship programmes, and investment funds can lose value. A qualifying fund investment should never be treated as a guaranteed-return product.

4. Comparing Caribbean, Turkish and Portuguese options

Dominica

US$200,000+

Direct citizenship route

Government contribution or approved real estate. Check the future of EU visa-free access carefully.

Antigua and Barbuda

US$230,000+

Direct citizenship route

Several family and investment options, with a five-day physical-presence requirement during the first five calendar years.

St. Kitts and Nevis

US$250,000+

Direct citizenship route

Established programme with contribution, real estate and public-benefit options.

Türkiye

US$400,000+

Direct citizenship route

Property purchase or alternative qualifying investments. Does not provide EU citizenship.

Portugal

€250,000+

Residence first, citizenship later if eligible

Cultural contribution, qualifying funds and other approved routes. No immediate passport.

The minimum amounts above are indicative published thresholds as of October 2026, not guaranteed all-inclusive costs. The qualifying route, fees, family size, investment restrictions and immigration rules can change. 

5. What additional costs should investors budget for?

The qualifying investment is only one part of the budget.

For example, a Dominica applicant considering a US$200,000 contribution should not assume that US$200,000 is the final amount needed for the entire application. The same applies to Turkish property purchases and Portugal's qualifying investment funds.

Request a written, itemised quotation before transferring money. Ensure it identifies which fees are refundable, which are not and when each payment becomes due.

6. Eligibility and the application process

Although the details vary by country, most investment migration applications involve several common stages.

1. Initial eligibility assessment: Confirm age, nationality, criminal history, family composition and any other applicable restrictions.

2. Source-of-funds verification: Prepare evidence showing how the investment capital was earned or acquired. Examples include business income, audited accounts, tax records, salary history, asset-sale documents and bank statements.

3. Select the correct investment route: Determine whether the contribution, property, fund or business route meets the current legal requirements.

4. Complete independent due diligence: Authorities may conduct identity, security, financial and background checks, including interviews.

5. Submit the application: Provide the required forms, certified documents, fees and investment evidence through the legally prescribed process.

6. Receive the decision and complete the qualifying investment: Follow the official sequence of approval, payment and investment completion. The order differs by programme.

7. Obtain citizenship or residence documentation: A passport follows citizenship approval; a residence permit does not itself confer citizenship.

Processing times are not guaranteed. An incomplete application, complex source of funds, additional security checks or administrative delays may lengthen the process.

7. Special considerations for Indian applicants

For Indian citizens, an investment migration plan involves both the destination country's immigration rules and India's legal, financial and citizenship requirements.

A. India does not generally permit dual citizenship

India does not recognise dual citizenship in the ordinary sense. Acquiring foreign citizenship voluntarily can affect Indian citizenship under Indian law. The implications should be reviewed before applying for a foreign passport.

The Overseas Citizen of India (OCI) scheme is not dual citizenship and does not provide an Indian passport or the full political rights of an Indian citizen.

Official reference: Ministry of Home Affairs — Overseas Citizenship of India.

B. Understand foreign-exchange and tax requirements

Indian residents should obtain professional advice before transferring substantial funds overseas. The applicable rules can depend on tax residence, the nature of the investment, the remittance route and the investor's circumstances.

Review the Foreign Exchange Management Act (FEMA), applicable Reserve Bank of India rules, tax reporting obligations and any requirements relating to foreign assets and income. Do not assume that an investment migration payment automatically qualifies under an ordinary overseas investment or remittance category.

C. Visa-free access is not permission to work

A second passport may make some journeys easier, but visa-free entry generally does not automatically authorise employment, long-term residence or settlement in another country.

For example, a Caribbean passport's travel arrangements should not be confused with a work permit for Canada or the right to live in the EU.

D. Check every family member's eligibility

Spouses, children and other dependants may be included only under the relevant programme's family rules. Age limits, financial dependency, relationship documentation, medical requirements and background checks can differ.

8. Risks and common scams to avoid

Investment migration requires substantial capital, so due diligence on the intermediary is as important as due diligence on the destination.

Be cautious if an agent:

- Promises a guaranteed passport or guaranteed approval.

- Advertises an unrealistically low all-inclusive price.

- Claims that citizenship automatically provides US, UK, Canadian or EU residence rights.

- Asks you to conceal the source of funds or provide misleading documents.

- Recommends a property without independent title and valuation checks.

- Cannot provide a written agreement, fee schedule or evidence of authorisation.

- Uses urgency to pressure you into sending money to a personal account.

For Caribbean citizenship programmes, verify the agent against the relevant government's authorised-agent list. For Türkiye, independently verify the property, title and investment certification. For Portugal, confirm that the investment qualifies under the current ARI rules and obtain independent legal advice.

9. Which programme is best for different objectives?

There is no single best passport-by-investment programme for every investor.

The best option depends on more than the advertised minimum. Consider where you want to live, which countries you need to visit, your family situation, the amount of capital you can commit, your tolerance for investment risk and the possibility of future policy changes.

For anyone whose main goal is EU access, the distinction between a Caribbean passport, Turkish citizenship and Portuguese residence is especially important.

Conclusion

Caribbean citizenship-by-investment programmes, Türkiye's direct citizenship route and Portugal's Golden Visa offer three different approaches to investment migration.

Dominica, Antigua and Barbuda, and St. Kitts and Nevis provide direct citizenship pathways for eligible investors. Türkiye offers another direct route through qualifying investment, including property. Portugal, by contrast, offers residence through eligible investments and the possibility of citizenship later, subject to the law and requirements in force.

The most important decision is not simply which passport costs the least. It is which programme legally and realistically meets your long-term objectives. Confirm the current official rules, calculate the full cost, investigate the investment and obtain independent legal and tax advice before committing funds.
