Citizenship By Investment
The Complete Guide to Second Passports Through Investment
Citizenship by investment allows an individual to acquire full, legal citizenship of another country by making a qualifying financial contribution, typically a government donation, a real estate purchase, or a business investment, rather than through birth, marriage, or years of prior residence. It is a lawful, government-regulated process operated directly by the countries that offer it, and it remains one of the fastest and most direct ways for individuals and families to secure a second nationality, expanded global mobility, and long-term security outside their country of origin.
Knightsbridge Group advises individuals, families, and businesses on citizenship and residency by investment across every major active programme in the world. This guide is intended as a starting point: a clear, current, and honest introduction to what citizenship by investment actually is, how it works, why people pursue it, and what to weigh before choosing a programme. As a fully licensed legal and immigration advisory firm with offices in Dubai, London, Milan and Istanbul, we’ve built this page to be useful on its own, not just a lead-in to a sales conversation.
What Is Citizenship by Investment?
Citizenship by investment, often abbreviated to CBI or CIP, is a legal pathway created by a sovereign government allowing qualifying applicants to obtain citizenship in exchange for a defined economic contribution. Depending on the programme, that contribution might take the form of a non-refundable donation to a national development fund, an investment in approved real estate, a contribution to government bonds, or a stake in a qualifying business.
Unlike residency by investment, which grants the right to live in a country but not the citizenship itself, citizenship by investment delivers full nationality, typically including a passport, the right to live and work in the country without restriction, and, in most programmes, the ability to pass that citizenship down to future generations. Most programmes require no prior residence, no interview in the traditional sense, and no language test, and can be completed in a matter of months rather than years.
Greater global mobility and security
Why Individuals and Families Pursue a Second Citizenship
The reasons vary by client, but a handful of motivations come up consistently in our work:
- Global mobility. A second passport can open visa-free or visa-on-arrival access to dozens or even well over a hundred additional destinations, meaningfully easing business travel, family visits, and relocation flexibility.
- A genuine Plan B. Political, economic, or social instability in a home country is one of the most common drivers we see, families want the option of an alternative base already secured before it’s ever needed, not scrambled together during a crisis.
- Tax and estate planning. Several citizenship by investment jurisdictions impose no personal income tax, no capital gains tax, and no inheritance tax, making a second citizenship a genuine component of a broader wealth and legacy strategy, not just a travel document.
- Business and investment access. Certain programmes carry specific commercial advantages, for example, Grenada’s citizens uniquely qualify for the US E-2 Investor Treaty visa, a benefit no other Caribbean citizenship currently offers.
- Family security across generations. Most programmes allow a spouse, children, and in many cases parents or even grandparents to be included in a single application, and the citizenship acquired typically passes to future descendants automatically.
From application to citizenship
How the Process Generally Works
While every country’s programme has its own specific rules, the underlying process follows a broadly consistent structure:
- Eligibility and programme selection. An initial assessment of the applicant’s goals, budget, family structure, and nationality determines which programme, or combination of programmes, genuinely fits.
- Due diligence and documentation. Applicants undergo background checks covering criminal history, financial standing, and source of funds, supported by certified documentation including passports, police clearance certificates, and proof of the funds being invested.
- Investment or contribution. Once an application is accepted for processing, the qualifying investment or donation is made, whether into a government fund, an approved property, or another qualifying route.
- Government review and approval. The relevant citizenship unit reviews the complete file, a process ranging from as little as one to two months in the fastest programmes to a year or more in others, depending on the country and current processing volumes.
- Citizenship and passport issuance. Once approved, citizenship is formally granted and a passport is issued, either through a local appointment, a designated overseas office, or, increasingly, fully remote processing.
Where citizenship programmes are available
The Regions Currently Offering Citizenship by Investment
The Caribbean remains home to the most established programmes in the world, including St Kitts and Nevis (the original programme, operating continuously since 1984), Grenada, Dominica, Antigua and Barbuda, and Saint Lucia. These programmes typically combine visa-free Schengen access with processing times that, while lengthening in recent years as due diligence has tightened, remain measured in months rather than years.
The Pacific offers Vanuatu, historically the fastest citizenship by investment programme anywhere in the world, though currently without visa-free access to the EU following a 2024 Schengen suspension, a genuinely important factor for anyone comparing options based on European mobility specifically.
Africa has recently entered the market through São Tomé and Príncipe, a newly launched programme offering one of the lowest entry costs available globally, alongside distinctive ties to the Community of Portuguese Language Countries.
Europe offers a smaller number of direct citizenship routes, most notably Malta, which grants an EU passport directly without the multi-year residency wait required by most European golden visa programmes, at a correspondingly higher cost and with more rigorous due diligence.
Beyond these regions, newer and more distinctive entrants continue to emerge, including Türkiye’s real estate-based route (paired with one of the longest new-resident tax exemptions in the world) and El Salvador’s Bitcoin-denominated Freedom Passport, each appealing to a different, more specific applicant profile than the mainstream Caribbean options.

Frequently Asked Questions
Is citizenship by investment legal?
Yes. Every programme referenced on this page is a formal, government-legislated route to citizenship, operated directly by the country in question, not a workaround or grey-market arrangement.
Do I have to give up my current citizenship?
In almost all cases, no. The large majority of citizenship by investment programmes, and most applicants’ home countries, permit multiple citizenship without requiring renunciation, though this should always be confirmed for your specific nationality before proceeding.
How long does citizenship by investment take?
This varies significantly by country, from as little as six to eight weeks in the fastest current programmes to a year or more in some of the more established Caribbean options, where processing volumes have increased substantially in recent years.
Can my family be included?
Most programmes allow a spouse and dependent children to be included in the same application, with many extending eligibility to parents, grandparents, and in some cases unmarried siblings, subject to age and dependency rules that vary by country.
Which programme is the best one?
There isn’t a single answer, the right programme depends on your priorities: speed, cost, visa-free access to specific regions, family structure, and long-term tax planning goals all point toward different answers for different clients.
