Passports on a desk next to a service fee schedule

Citizenship by investment explained: how it works, what it really costs a family, how due diligence works and the risks people discover too late.

Key takeaways

  • The advertised minimum, now at least USD 200,000 in the Caribbean, is not the real cost. Fees for a family of four can add around a third on top.
  • Due diligence covers every adult in the application and focuses on how you built your wealth, not only where this payment comes from.
  • Visa-free access is controlled by other countries and has already been withdrawn from several programme passports.
  • A second passport doesn't change your tax residency, and it can cost you your first citizenship.
  • Many people asking about a second passport actually need a second residency.

The advert says USD 200,000. It's a tidy figure, and for many families it sits comfortably inside the budget they've already set aside for a Plan B. Then the paperwork begins. Once government processing fees, due diligence charges for every adult, passport fees and professional fees are added, a family of four usually ends up well above that number. That's before anyone has asked them to prove, with documents, where every significant sum in their financial life came from.

Citizenship by investment is often described as buying a passport, and that description gets two things wrong. You aren't buying anything off a shelf. You're applying to a sovereign state for nationality under its own citizenship law, and that state can refuse you, change the terms halfway through or, in certain circumstances, take the citizenship back years later. The price in the advert is also a minimum contribution rather than the real cost.

This is part 2 of our series on second citizenship, following our comparison of the four main routes. Here we take a close look at the investment route: how programmes work, what they cost a real family, how due diligence works, which programmes are active as of October 2026, and the risks that tend to surface only after the money has moved.

How does citizenship by investment work?

Under citizenship by investment, a country grants full citizenship to a foreign national who makes an approved economic contribution and passes the government's background checks. Unlike ordinary naturalisation, it doesn't require years of prior residence.

The legal basis is a specific provision in the country's citizenship law. St Kitts and Nevis introduced the first modern programme in 1984, and most others follow a similar model. A dedicated government unit receives your application through a licensed local agent, commissions independent background checks, interviews you and decides. Once you're approved, you make the investment, receive a certificate of naturalisation and apply for your passport.

What you end up with is citizenship in the full legal sense, which you can usually pass on to your children. That's also the root of the controversy. Ordinary naturalisation assumes you've built a life in the country first, and most investment programmes have never asked for that. The missing "genuine link" is what the European Union now objects to, as we'll see further down.

What investment routes do citizenship by investment programmes offer?

Most programmes offer a non-refundable government donation or a qualifying real estate purchase. Less often, they offer government bonds or a business investment.

The donation route is the simplest. You pay into a national development fund and the money is gone, but you avoid property management, holding periods and resale questions. It's usually the cheapest route in absolute terms and the fastest to complete.

The real estate route looks more attractive because you seem to keep an asset, but in practice it's often overrated. You can only buy units in government-approved developments, and those units are priced for programme buyers rather than for the local market. You'll also pay government fees on top of the purchase price. In Dominica, for example, the official programme states a minimum property value of USD 200,000, government fees starting from USD 75,000 and a holding period of at least three years. After that period, your exit depends largely on another programme applicant wanting the same unit, so you shouldn't count on getting your purchase price back.

Bonds and business routes are less common. Saint Lucia offers non-interest-bearing government bonds of USD 300,000, held for five years, and Antigua and Barbuda's business route starts at USD 1.5 million for a single investor. Türkiye has no donation route at all. Instead it asks for USD 400,000 in real estate or USD 500,000 in deposits, bonds or certain funds, each held for three years.

How long does the process take, and which family members can you include?

The Caribbean programmes typically take between about five and eighteen months from application to passport, depending on the country and how clean your file is.

Averages reported by the trade publication IMI Daily for late 2025 put St Kitts and Nevis at around five months and Saint Lucia at around eighteen, with the others in between, and individual cases varied widely. Every Caribbean programme now includes a mandatory interview, in person or by video. The preparation before you submit takes time too. Collecting apostilled documents, police certificates and financial records for several family members can easily take two or three months.

Your spouse and children under 18 can almost always be included. Many programmes also accept financially dependent adult children, often up to 30 if they're still studying, and some accept parents or grandparents. Dominica, for instance, accepts those over 65 who are substantially supported by you. Each person adds fees, and every adult goes through the same checks you do, so one family member's history can hold up the whole application.

What does citizenship by investment really cost?

The real citizenship by investment cost is the minimum contribution plus a layer of fees. In our illustrative family example below, that layer adds about a third on top, before any holding-period costs on real estate.

The fees on top of the minimum investment

Government processing fees come first. Antigua and Barbuda, for example, charges USD 10,000 for a single applicant and USD 20,000 for a family of up to four, as of October 2026.

Due diligence fees are charged per person. St Kitts and Nevis charges USD 10,000 for the main applicant and USD 7,500 for every dependant aged 16 or over. Antigua and Barbuda charges USD 8,500 for the main applicant, USD 5,000 for a spouse and between USD 2,000 and 4,000 for older children and parents. These fees are normally non-refundable, even if you're refused.

Larger families often pay a higher contribution as well. In St Kitts and Nevis, the USD 250,000 contribution covers a family of up to four. Each additional dependant under 18 costs another USD 25,000, and each dependant aged 18 or over another USD 50,000.

Then come the costs no government publishes. Professional and legal fees vary widely, so get them in writing before you start. Documents, translations and medical checks add a few thousand more. Where a programme requires physical presence, as Antigua and Barbuda now does, travel and time away belong in the budget too.

Worked example: a family of four

This is an example case. A couple in their mid-forties apply with two children aged 17 and 13 through Antigua and Barbuda's National Development Fund. The government figures below come from the official fee schedule as of October 2026. The professional and document costs are assumptions for illustration only.

Cost item Amount (USD)
National Development Fund contribution 230,000
Government processing fee (family of up to four) 20,000
Due diligence: main applicant 8,500
Due diligence: spouse 5,000
Due diligence: two children aged 12–17 (2 × 2,000) 4,000
Passport fees (4 × 300) 1,200
Subtotal, government costs 268,700
Professional and legal fees (illustrative assumption) 30,000
Documents, translations, medicals, travel (illustrative assumption) 5,000
Estimated total about 303,700

The headline contribution makes up roughly three quarters of the total. Had the family chosen real estate, the entry price would have been higher and government fees would still have applied. Around USD 300,000 would also have sat in a property with an uncertain resale value for years. In either case, they'd need to plan for 30 days on the island within the first five years.

How does citizenship by investment due diligence work, and why do applications get refused?

Due diligence means the government checks your identity, criminal record, sanctions exposure, political connections, media coverage and the origin of your money, usually through independent investigation firms. It does the same for every adult in your application.

The checks go further than most applicants expect. Investigators search international sanctions and law enforcement databases, look for adverse press in several languages and verify your business history. They also check whether you're a politically exposed person, meaning someone who holds or has held a prominent public role, or is closely connected to one. The interview then tests whether what you've written matches what you say.

Applications are rarely refused over one dramatic finding. More often it's an inconsistency, such as an undisclosed visa refusal, a directorship missing from the form, a gap between declared income and assets, or a family member's business partner on a sanctions list. Programmes generally don't explain refusals, and a refusal stays with you. You'll usually have to declare it on future visa and citizenship applications, and the Caribbean governments now share information through a regional regulator.

Source of funds versus source of wealth

Source of funds is where the money for this particular investment comes from. Source of wealth is how you built your overall net worth. Due diligence teams ask for both, and the second is where most files get difficult.

Take an entrepreneur who sold a company in 2019, invested part of the proceeds, and now holds a mix of property, listed shares and some cryptocurrency. They'll need the sale agreement, evidence of the payment arriving, tax filings from the year of sale and a clear trail from that money to today's assets. Crypto gains without exchange records, cash-heavy businesses, informal family loans and undocumented inheritances regularly cause delays. Banks ask for the same paper trail when you open accounts internationally, which is why GWS looks at citizenship, banking and company structure together rather than as separate projects. If you can't document your wealth comfortably today, that's the first thing to fix, whatever route you choose.

Which citizenship by investment programmes are still active in 2026?

As of October 2026, the established active programmes are Türkiye and the five Eastern Caribbean programmes: Antigua and Barbuda, Dominica, Grenada, St Kitts and Nevis, and Saint Lucia. Malta's programme has ended, and Vanuatu's passport has lost visa-free access to the Schengen area.

Since July 2024, the five Caribbean governments have applied an agreed minimum contribution of USD 200,000 and declared discounting below it illegal. They have since set up a regional regulator to license agents and enforce common due diligence standards. The table shows how the programmes compare as of October 2026. Caribbean contribution figures come from official government sources. Processing times are reported averages and should be read as indications only.

Programme Donation minimum Real estate minimum Family of four Reported average processing Residence requirement Visa-free: Schengen / UK
Antigua and Barbuda USD 230,000 USD 300,000 Same contribution; processing fee USD 20,000 about 14 months 30 days within five years (applied in practice; amending law before parliament) Yes / Yes
Dominica USD 200,000 (single applicant) USD 200,000 plus government fees from USD 75,000; three-year hold Contribution rises with each dependant about 9 months None, though in-person passport collection has been announced Yes / No (since July 2023)
Grenada USD 235,000 Available at a higher threshold Same contribution up to four about 7 months None at present; regional 30-day rule expected Yes / Yes
St Kitts and Nevis USD 250,000 USD 325,000 (approved development) or USD 600,000 (private) Same contribution up to four about 5 months None at present; regional 30-day rule expected Yes / Yes
Saint Lucia USD 240,000 USD 300,000 plus fees Applicant plus up to three dependants included about 18 months 30-day rule approved, start date not confirmed Yes / No (since March 2026)
Türkiye Not offered (USD 500,000 deposit, bond or fund routes) USD 400,000; three-year hold Spouse and children under 18 included 4 to 9 months None No / No

The table leaves out the United States. Antigua and Barbuda and Dominica have faced US entry restrictions since 1 January 2026, and these go further than a shorter visa: the presidential proclamation behind them suspended the issue of new visitor, student, exchange and immigrant visas to their citizens, with exceptions for people who already held a valid visa on that date. Separately, the State Department cut the validity of their visitor visas to three months and a single entry, down from ten years. Grenada, on the other hand, is the only Caribbean programme whose citizens can apply for the US E-2 treaty investor visa. For some applicants, that matters more than any headline figure.

St Vincent and the Grenadines has announced a programme for 2026, but no final terms had been publicly confirmed at the time of writing. Programmes from other small states with short track records deserve extra caution.

What are the citizenship by investment risks most people discover too late?

The main risks sit outside your control. Programme rules change, other countries withdraw visa-free access, citizenship can be revoked in certain cases, and banks treat some passports with suspicion. On top of that, the passport does nothing for your tax position.

Programme changes, price increases and suspensions

The rules you apply under aren't necessarily the rules you'll live under. Several Caribbean programmes roughly doubled their minimum when the regional floor took effect in 2024. Türkiye raised its real estate threshold from USD 250,000 to USD 400,000 in 2022. When Malta ended its programme after the court ruling described below, applications still under review were voided.

EU and international pressure

On 29 April 2025, the Court of Justice of the European Union ruled that Malta's investor citizenship scheme breached EU law. Granting nationality in exchange for payment, without a genuine link to the country, amounted to commercialising EU citizenship. Since 30 December 2025, a revised EU regulation has allowed the EU to suspend visa-free travel for countries that run investor citizenship schemes without such a link.

In July 2026, the Antigua and Barbuda government reported that the European Commission had written to all five Caribbean programme countries in a letter dated 25 June. It asks them to end their programmes by 1 June 2028. The Commission hasn't published the letter itself, although Antigua released its own copy, and the five governments have said they'll keep negotiating, so the outcome is open. It is, however, the most serious pressure these programmes have faced.

Losing visa-free access after you've invested

This is the risk that matters most. Visa-free travel is usually what people are paying for, and it's controlled by the destination countries rather than the country that issues your passport.

Vanuatu shows how it plays out. The EU first suspended visa-free travel for Vanuatu passports issued after May 2015. In December 2024 it removed Vanuatu from its visa-free list altogether, citing security and migration risks from its investor citizenship scheme. The UK imposed visa requirements on Dominica in July 2023, citing abuse of its programme, and on Saint Lucia in March 2026, mainly over a sharp rise in asylum claims, though the island's programme was cited alongside them. Either way, people who'd paid for UK visa-free travel lost it overnight, and none of them got a refund.

Revocation of citizenship

Citizenship granted through investment can be withdrawn if it was obtained through false or concealed information. In some countries, serious later offences are also grounds. After Cyprus closed its programme in 2020, it revoked the citizenship of 360 people by September 2025, and 259 of them were family members rather than the investors themselves. Türkiye went considerably further in August 2026, when its interior ministry cancelled or withdrew the citizenship of 6,134 people after inspectors found inflated or irregular property valuations behind the applications of 1,413 investors. Your spouse and children's status is tied to the honesty and completeness of your application.

How banks and compliance teams react

Banks don't take a passport at face value. In 2018, the OECD warned that some citizenship and residence by investment schemes could be misused to hide assets from automatic tax information exchange. It told financial institutions they could ask additional questions where tax residence is in doubt. A 2014 US Treasury advisory warning banks about the misuse of St Kitts and Nevis passports stayed in force until February 2026, nearly twelve years later.

In practice, you should expect to declare all your nationalities and tax residencies when you open accounts. Presenting an investment passport while leaving out your original nationality is the pattern compliance teams are trained to spot.

Tax: a second passport doesn't change your tax residency

For almost everyone, tax follows where you live, not which passport you hold. If you get a Caribbean passport but continue to live, work and keep a home in Germany, India or the UK, your tax position there doesn't change. The main exception runs the other way: US citizens remain taxable in the US wherever they live.

Before applying, also check whether your current country allows dual nationality at all. Some don't. Others, such as Austria in most cases, remove your citizenship when you voluntarily acquire another, so the new passport could cost you the one you already hold.

Who is citizenship by investment for, and who isn't it for?

Citizenship by investment fits people whose current passport genuinely holds back their travel or business and who can document their wealth without difficulty. It's a poor fit if you're really looking for lower taxes or a new place to live.

It makes most sense when visa applications are a recurring cost in your working life and you're thinking about your children's mobility over decades rather than years. You should also be comfortable treating a donation as money spent rather than money invested.

The passport alone won't lower your tax bill. It also gives you the right to live only in the issuing country, so a Caribbean passport won't let you settle in Europe or the Gulf. If your wealth is hard to document, or your home country would strip your citizenship, those are problems to solve before you apply.

Many people who start out asking about a second passport actually need a second residency. If what you want is the right to live in Dubai, bank there and build a base outside your home country, a UAE residence visa addresses that directly and a Caribbean passport doesn't. In that case, the more useful question is which residency fits your plans, rather than which passport to buy.

Conclusion

Citizenship by investment is a legitimate and increasingly regulated route to a second nationality, but it's a bigger decision than the adverts suggest. Before you commit, be clear about which problem you're solving and whether a residency would solve it more cheaply. Budget for the full cost for every family member rather than the headline minimum, and be honest about whether you can document your source of wealth today. Ask yourself how much of the passport's value depends on visa-free access that other countries could withdraw, and check your home country's dual nationality rules. The Caribbean programmes are under real pressure, with an EU deadline of June 2028 reportedly on the table, so the passport you'd hold in five years may not offer exactly what it offers today.

The second citizenship series

FAQ

What is the cheapest citizenship by investment programme?

As of October 2026, the lowest published donation minimum among the established programmes is Dominica's USD 200,000 for a single applicant. The total cost for a family depends on fees and dependants, though, and the passports differ in visa-free access. The lowest headline price is rarely the lowest total cost.

How long does citizenship by investment take?

Reported averages for the Caribbean programmes range from about five months to about eighteen months, plus preparation time. Türkiye typically takes four to nine months.

Does citizenship by investment reduce my taxes?

No. Tax residency depends mainly on where you live and spend your time, not on your passport. A second passport on its own doesn't change your tax position.

Can citizenship by investment be taken away?

Yes, in certain cases, mainly where it was obtained through false or concealed information. Cyprus revoked 360 citizenships granted under its former programme by September 2025, most of them belonging to family members.

Can I include my parents in a citizenship by investment application?

Often, yes, but the rules vary. Dominica, for example, accepts parents and grandparents over 65 who are substantially supported by the applicant. Each additional person adds fees and goes through due diligence.
