How Many Citizenships Can You Have in 2026: A Guide by Mirabello Consultancy

Last updated: March 2026

Humanity's dream of becoming a multi-planetary species is still a long way off—about 225 million kilometers to Mars, give or take. But while interplanetary passports aren't an option yet, collecting dual, triple, or even multiple citizenships right here on Earth is far more achievable. So, how many citizenships can you have? The answer depends on where you're born, your ancestry, and the laws of different nations. Some countries welcome multiple nationalities without restriction, while others make you choose just one.

In an increasingly globalised world, holding more than one passport isn't just a novelty—it's a strategic advantage. Whether it's for travel freedom, business opportunities, or a plan B in times of uncertainty, multiple citizenships can open doors (and borders) in ways a single nationality simply can't. This article will explore the possibilities, the perks, and the paths to acquiring multiple citizenships—because while Mars may be out of reach, expanding your global footprint is entirely within grasp.

How Many Citizenships Can You Have? Understanding the Global Rules

The short answer: as many as the countries involved will allow. There is no international treaty or global body that caps the number of nationalities a person can hold. Each sovereign nation sets its own rules, and those rules vary enormously.

Broadly speaking, countries fall into three camps:

• Permissive nations: Countries such as the United Kingdom, France, Portugal, Ireland, Australia, Canada, and Switzerland either explicitly allow multiple citizenship or have no laws requiring renunciation. Citizens of these countries are free to acquire additional nationalities without consequence.
• Conditional or tolerated nations: Some countries do not officially recognise dual citizenship but turn a blind eye in practice, or only require renunciation upon voluntary naturalisation elsewhere. The United States falls into a nuanced middle ground here — it technically discourages dual citizenship but does not generally strip nationality from those who acquire it elsewhere.
• Restrictive nations: Countries such as Germany (with limited exceptions), China, Japan, India, the UAE, and Saudi Arabia typically require individuals to renounce previous nationality upon naturalisation, or strip citizenship automatically when a foreign nationality is acquired.

In practical terms, many UHNW individuals hold three, four, or even five passports simultaneously — particularly when those passports are from permissive nations. A British-born entrepreneur, for example, might also hold Irish citizenship through ancestry, a Grenadian passport acquired through investment, and Portuguese citizenship following five years of residency. All four are perfectly legal and mutually compatible.

The key is conducting careful due diligence on each country's laws before embarking on any citizenship acquisition strategy. This is precisely where specialist guidance from a firm such as Mirabello Consultancy proves invaluable.

How Many Citizenships Can You Have Through Investment? The Top Programmes in 2026

Citizenship by investment (CBI) remains one of the most efficient and legally robust routes to acquiring an additional passport. These programmes, operated by sovereign governments, grant full citizenship — and therefore a passport — in exchange for a qualifying economic contribution to the host nation. Below is a curated overview of the leading programmes available in 2026.

Caribbean CBI Programmes

The Caribbean continues to offer some of the world's most accessible and well-regarded CBI programmes. Processing times are swift, family inclusion is generous, and the resulting passports provide impressive visa-free travel.

• St Kitts & Nevis: The world's oldest CBI programme, established in 1984. Investment options include a non-refundable contribution to the Sustainable Island State Contribution (SISC) from $250,000 for a single applicant, or real estate investment from $400,000. Visa-free or visa-on-arrival access to 157+ countries, including the Schengen Area and the UK. Processing time: 45–60 days (Accelerated Application Process) or 3–4 months (standard). Learn more on our St Kitts & Nevis programme page.
• Dominica: Consistently rated among the most cost-effective CBI options globally. Non-refundable government contribution from $100,000 for a single applicant. Visa-free access to 140+ countries. Processing time: 3–5 months.
• Grenada: The only Caribbean CBI programme offering a pathway to an E-2 US investor visa. Government contribution from $235,000 or real estate investment from $270,000. Visa-free or visa-on-arrival access to 144+ countries. Processing time: 4–6 months. Explore our Grenada citizenship by investment programme for full details.
• Antigua & Barbuda: Government contribution from $230,000. Visa-free access to 150+ countries. Unique five-year renewable passport. Processing time: 3–5 months.
• St Lucia: Government contribution from $240,000 for a single applicant. Visa-free access to 146+ countries. Processing time: 3–6 months.

European CBI and Golden Visa Programmes

European citizenship — particularly within the European Union — remains the gold standard for global mobility. An EU passport provides the right to live, work, and study across all 27 member states, alongside visa-free access to 185+ countries.

• Malta: The EU's only active direct citizenship by investment programme. The Malta Exceptional Investor Naturalisation (MEIN) programme requires a minimum direct investment of €690,000 (after one year of residency) or €990,000 (after three years), plus a €10,000 charitable donation and a property purchase or lease. A Maltese passport grants visa-free access to 188+ countries including the USA and Canada. Processing time: 12–36 months. Explore our Malta citizenship by investment programme page for a full breakdown.
• Vanuatu: Although not European, Vanuatu's Development Support Programme (DSP) offers one of the fastest CBI routes globally, with passports issued in as little as 30–60 days. Investment from $130,000. Visa-free access to 98+ countries including the Schengen Area and UK.
• Jordan: Citizenship from a $750,000 investment in a Jordanian company or $1,000,000 deposited in a Jordanian bank. Processing time: 3–6 months.

Eligibility: Who Can Apply for Multiple Citizenships?

Eligibility for CBI programmes — and for multiple citizenship more broadly — is governed by a combination of the applicant's existing nationality, personal background, and the specific requirements of each programme. Here is what you need to know:

Eligibility for CBI Programmes

While each programme has its own criteria, the following requirements are broadly standard across most reputable CBI jurisdictions:

• Age: Principal applicants must typically be at least 18 years of age. Children and grandchildren under 18 (and in some cases up to 26–30 if financially dependent) can be included as dependants.
• Clean background: All programmes conduct thorough due diligence checks. A clean criminal record is an absolute requirement. Individuals subject to international sanctions, those with serious criminal convictions, or those from countries under embargo (such as North Korea, Iran, or Russia under certain programmes) are typically ineligible.
• Financial standing: Applicants must demonstrate that investment funds are legitimate. Source of wealth and source of funds documentation is standard.
• Health: Some programmes require a medical examination to confirm the applicant does not pose a public health risk.
• No residency requirement (CBI): Unlike golden visa or residency by investment programmes, most CBI programmes do not require the applicant to physically reside in the country before or after citizenship is granted.

Restrictions Based on Existing Nationality

As noted above, certain nationalities face restrictions. Chinese nationals, for instance, may risk losing Chinese citizenship upon acquiring a second passport, since China does not recognise dual nationality. Similarly, Indian nationals who acquire foreign citizenship automatically lose their Indian citizenship — although the Overseas Citizen of India (OCI) card provides many of the practical benefits of citizenship. Prospective applicants from restrictive countries should take careful legal advice before proceeding.

The Application Process: How to Acquire Multiple Citizenships Legally

The process of acquiring citizenship through investment follows a broadly consistent structure across most programmes, though the details vary. Here is a step-by-step overview of the typical journey:

1. Initial consultation and programme selection: The first step is assessing which programme — or combination of programmes — best meets your objectives, whether that is maximum visa-free access, an EU passport, business flexibility, or rapid processing. This is where Mirabello Consultancy's expertise delivers immediate value. Book your free consultation here.
2. Document preparation: Gathering certified copies of passports, birth certificates, marriage certificates, police clearance certificates, proof of wealth, bank statements, and business documentation. Our team provides a detailed checklist and assists with apostille and notarisation.
3. Due diligence: All CBI programmes conduct multi-tier due diligence checks on applicants and their family members. Reputable programmes typically use independent third-party firms. This stage may take 4–12 weeks depending on the programme.
4. Investment: Once the application is approved in principle, the qualifying investment is made — whether a government fund contribution, real estate purchase, or business investment. In many programmes, the investment is held in escrow until formal approval.
5. Passport issuance: Upon full approval, a certificate of naturalisation and the new passport are issued. For some programmes (such as Vanuatu), this can happen in as little as 30 days from investment; for Malta, the full timeline is 12–36 months.
6. Ongoing compliance: Some programmes (notably Malta) require the applicant to maintain their investment for a minimum period (typically three to five years) and to demonstrate genuine links to the country.

Key Benefits of Holding Multiple Citizenships

For HNW and UHNW individuals, the strategic value of multiple passports extends well beyond the convenience of queue-jumping at immigration. Here are the most significant benefits our clients seek:

• Global mobility: A portfolio of complementary passports can unlock visa-free access to virtually every major economy and travel destination in the world. Combining, for example, a Caribbean CBI passport (for Schengen and UK access) with an EU passport (for global reach) and a residency in a third country creates an extraordinarily flexible global profile.
• Tax optimisation: Many CBI jurisdictions — including the Caribbean nations — impose no income tax, capital gains tax, inheritance tax, or wealth tax. Establishing genuine tax residency in a zero or low-tax jurisdiction, combined with citizenship, can form a legitimate and highly efficient part of a global tax strategy. (Mirabello always recommends clients seek qualified independent tax advice.)
• Business and investment access: Certain passports open doors that others cannot. A Grenadian passport, for example, uniquely facilitates the US E-2 investor visa. A Maltese (EU) passport removes barriers to operating businesses across Europe's single market.
• Personal security and optionality: In an era of geopolitical uncertainty, a second citizenship is, for many clients, a genuine insurance policy — a plan B that ensures freedom of movement and a safe harbour for oneself and one's family regardless of what happens in the home country.
• Legacy planning: Citizenship acquired through investment is typically passed to future generations by descent, creating a lasting benefit for children and grandchildren.
• Quality of life: Access to superior healthcare systems, educational opportunities, and a more favourable living environment for family members are consistently cited by our clients as motivating factors.

Family Inclusion: Bringing Your Loved Ones Along

One of the most appealing features of leading CBI programmes is the ability to include family members in a single application, often at a modest incremental cost. Here is how family inclusion typically works:

• Spouse or partner: All major CBI programmes include the principal applicant's spouse or legally recognised partner. The additional government fee varies by programme, typically ranging from $25,000 to $75,000.
• Children: Dependent children are included in most programmes. The age limit is usually 18, though many programmes extend this to 25–30 for financially dependent students. Some programmes also allow children under guardianship.
• Parents and grandparents: Several programmes, including Malta, Grenada, Antigua & Barbuda, and St Kitts & Nevis, allow the inclusion of the principal applicant's parents and/or grandparents (above a certain age threshold, typically 55–65) as dependants.
• Siblings: A smaller number of programmes allow inclusion of unmarried or financially dependent siblings.

Family inclusion makes CBI programmes particularly attractive for parents seeking to secure their children's futures with an EU passport or enhanced global mobility, without each family member needing to make a separate application. For tailored advice on structuring a family application, we encourage you to schedule a confidential consultation with our team.

Frequently Asked Questions: How Many Citizenships Can You Have?

Is there a legal limit to how many citizenships you can hold?

No, there is no international law or treaty that sets a maximum number of citizenships a person can hold. The limit — if any — is determined by the domestic laws of each country involved. In practice, individuals from permissive nations (such as the UK, France, Australia, or Ireland) can hold as many citizenships as they are able to qualify for and acquire. Some people legally hold four, five, or even more passports simultaneously.

Which countries do not allow dual or multiple citizenship?

Countries that currently restrict or prohibit dual citizenship include China, India, Japan, Germany (with limited exceptions), the UAE, Saudi Arabia, Singapore, Indonesia, and several others. In most cases, nationals of these countries who voluntarily acquire a foreign citizenship risk losing their original nationality. The rules are nuanced and subject to change, so it is always advisable to seek legal advice specific to your nationality before proceeding.

How quickly can I obtain a second citizenship through investment in 2026?

Processing times vary significantly by programme. The fastest route to a second passport is currently the Vanuatu Development Support Programme, which can issue a passport in as little as 30–60 days. Caribbean programmes such as St Kitts & Nevis (via the Accelerated Application Process), Dominica, and Grenada typically process applications in 3–6 months. The Malta MEIN programme, which grants an EU passport, takes 12–36 months. All timelines are subject to the completeness and accuracy of documentation provided.

What is the most affordable citizenship by investment programme in 2026?

Dominica's citizenship by investment programme remains among the most accessible in terms of upfront investment, with a non-refundable government contribution starting from $100,000 for a single applicant. Vanuatu's DSP starts from $130,000. It is important to note, however, that government fees, due diligence costs, and professional advisory fees are additional, and the total cost of the process will be higher than the headline investment figure. Mirabello Consultancy provides full, transparent cost projections for all programmes.

Can my children obtain citizenship if I invest?

Yes. All major citizenship by investment programmes allow dependent children to be included in the principal applicant's application. In most cases, children under 18 are included, and many programmes extend eligibility to financially dependent children aged up to 25 or 30 (typically full-time students). Children granted citizenship through these programmes generally retain that citizenship for life and can pass it to their own children by descent, creating a multi-generational benefit.

Does holding multiple citizenships affect my tax obligations?

Citizenship and tax residency are separate legal concepts in most countries. Simply holding a second passport does not, in itself, create a tax obligation in the issuing country — unless you also establish residency there. The significant exception is the United States, which taxes its citizens on worldwide income regardless of where they live. For US citizens or those considering acquiring US residency or citizenship, careful tax planning is essential. Mirabello Consultancy strongly recommends all clients engage an independent tax adviser as part of their investment migration strategy.

Is citizenship by investment legal and secure?

Yes, citizenship by investment programmes are entirely legal. They are sovereign government programmes, enacted through national legislation, and the resulting citizenship and passports are indistinguishable from those acquired through birth or naturalisation. The Caribbean programmes are formally regulated by their respective governments, and the Malta MEIN programme operates under EU oversight. Applicants undergo rigorous due diligence checks, which actually enhances the reputation and security of these passports internationally.
