Unlocking Global Mobility: Easiest Countries for Second Citizenship and Passports in 2025

Our world today has changed a lot. From rising taxes to the growing political and economic struggles, and as such putting all your investment in one nation seems to be risky.  In other words, having only one passport can severely limit you. Mobility is power. It’s not just about money anymore. More and more people are asking, “Where else can I live if things change at home?” or “Where can I find better opportunities for myself and my family?” The answer is simply: a second citizenship.

A second citizenship can give you visa-free access to over 100 countries, help you optimise taxes, and protect your assets. For your family, it means better healthcare, world-class education, and lifestyle options. In 2024 alone, a study by Henley & Partners reported that interest in second citizenships rose by over 38%. That’s because a second passport is no longer just a luxury, but a strategic move for global mobility.

In this guide, we’ll explore some of the easiest ways to obtain a second citizenship in 2025, from investment programs to naturalisation routes. So, whether you’re a founder who needs mobility, an investor thinking ahead, or just someone who wants a solid Plan B (that honestly feels more like Plan A), this is for you.

Top Paths to a Second Citizenship

There are several pathways you can follow to get a second passport. Depending on your background, goals, and resources, the right path could look very different for you compared to your neighbors’.   However, here are the three most common and easiest routes:

• Citizenship By Investment (CBI)
• Citizenship By Descent (CDI)
• Citizenship By Naturalisation (CNI)

Citizenship By Investment (CBI)

If you want a fast process, then Citizenship by Investment (CBI) is most likely the best route for you. You don’t have to worry about long waiting times, residency requirements, or language exams. With CBI, you’re making a straightforward investment in your future by securing a second passport legally with your money.

CBI programs are especially popular in places like the Caribbean, parts of Europe, and the South Pacific. These places offer perks such as visa-free access to key markets, tax advantages, and a secure exit plan if things go sideways in your home country, whether due to political or economic reasons.

Top countries to consider:

1. St. Kitts & Nevis: You can get citizenship in just 4-6 months with a minimum investment of $250,000 to their Sustainable Growth Fund. In exchange, you get visa-free access to over 150 countries, including the EU and the UK.
2. Antigua & Barbuda: This is perfect for families. For just $100,000, a family of four can secure citizenship, with access to more than 145 visa-free destinations. Plus, you only need to visit Antigua once every five years to keep your citizenship.
3. Malta: Malta’s CBI program is a premium option, offering full EU citizenship for an investment of around €750,000. This opens up 180+ countries, the Schengen Zone, and EU residency rights. It is best if you’re looking to establish a strong presence in Europe.
4. Vanuatu: Vanuatu offers one of the fastest CBI processes, with citizenship granted in as little as two months. Starting at $130,000, it’s a solid choice for those prioritising speed and simplicity, though its visa-free options are more limited compared to others.

The benefits you’ll enjoy go beyond just global mobility. Many of these countries offer tax incentives, such as zero taxes on global income, capital gains, and inheritance, depending on where you live. If your goal is to structure your life and wealth internationally, CBI is one of the most effective tools in your arsenal.

But to be clear, CBI is not for everyone. You’ll need to pass rigorous due diligence checks, and your investment must come from clean sources.

Citizenship by Descent

You might not even realise but chances are, the easiest route to your second passport is already hiding in your family tree. Citizenship by descent (also called jus sanguinis) allows individuals to claim nationality through their parents, grandparents, or even great-grandparents, depending on the country. It’s usually low-cost or free, involves minimal residency requirements, and gives you full rights as a native citizen.

If you have European or Latin American roots, this is your golden ticket.

Top countries to explore:

1. Italy: You can claim Italian citizenship if you can prove an unbroken bloodline, even way back to great-grandparents, as long as no one in the chain renounced their citizenship. It doesn’t come with any language requirement, and once granted, you gain access to EU residency, healthcare, and education.
2. Ireland: If one of your grandparents was born in Ireland, you’re eligible. The process is smooth, and you gain EU mobility and a respected passport with visa-free access to over 190 countries.
3. Poland: With the right documentation, you can go back as far as your great-grandparents. Poland’s passport ranks high globally and opens doors across Europe.
4. Argentina: Latin American countries are often overlooked, but Argentina allows you to claim citizenship through descent with fewer bureaucratic hurdles, and you don’t even have to worry about any residency requirement.

According to a 2024 survey by Global Citizen Solutions, nearly 12% of individuals in the U.S. and Canada qualify for a second passport through descent but have yet to claim it.

This could be you. So start digging into your family tree, and maybe you might just qualify for a second passport based on your ancestry.

Citizenship By Naturalisation

Not everyone has the luxury of ancestry or lots of money, but that doesn’t mean the door is closed. Some countries give people a shot at citizenship through naturalisation. You just need to know where to look and be willing to play the long game.

We’re talking about low barriers, short timelines, and minimal language or income requirements.

Top naturalisation-friendly countries:

1. Paraguay: With just 183 days of residency per year for three years, you can apply for citizenship. You don’t even have to stay behind after your initial registration. The tax rules there are also favourable—territorial taxation and almost zero tax on income earned abroad.
2. Uruguay: This is a welcoming and surprisingly easy country to settle into. Live there for just 3 years (or 5 if you’re single), and you can apply for citizenship. No language test, and you get a strong passport with visa-free access to 150+ countries.
3. Brazil: Offers citizenship after just 4 years of residency and less if you marry a Brazilian or have a Brazilian child. No renunciation is required, and Brazil recognises dual citizenship by default.
4. Turkey: Although known for its investment route, Turkey also allows naturalisation through long-term residency. Five years of legal stay and basic language proficiency can get you in.

These countries might not be the flashiest on paper, but they’re residency-friendly, tax-light, and politically stable. Naturalisation isn’t instant, but certainly a low-pressure route that pays off in the end.

What to Consider Before Choosing a Country

Before you commit to any country, here are three important things that you need to consider:

1. Visa-Free Travel

Some passports open more doors than others. If you’re going through the effort (and expense) of getting a second one, it better be worth it. Take St. Kitts and Nevis, for instance, it offers visa-free access to over 150 countries, including the UK and Europe’s Schengen Zone. That’s great if your primary passport is more limited.

But if you already have strong mobility, you might consider a passport that adds strategic reach, like Turkey, which opens the door to Asia and the Middle East, or Vanuatu, a Pacific gem that gets you into countries like Russia and Singapore without a visa.

So ask yourself: Where do you want easier access? What gaps do you want to fill?

2. Tax Benefits

This one’s big. A second passport can significantly enhance your tax strategy if you choose correctly.  Countries like Paraguay, Vanuatu, and St. Kitts offer tax systems where they don’t tax income earned outside their borders. That’s a huge win, especially for entrepreneurs, investors, or anyone running a remote business

Others, such as Portugal or Malta, offer you that desirable European lifestyle, but they also come with stricter tax residency rules. It’s not necessarily a deal-breaker, but it’s something you’ll want to navigate carefully.

3. Lifestyle Fit

While some countries are great on paper, they’re not exactly where you’d want to stay and build your life. Even if you’re not planning to relocate full-time, the option to live, invest, or raise a family there should still feel like an upgrade.

That’s why places like Uruguay, Poland, and Malta often top the list if you are from a developing country. They offer stability, safety, a good standard of living, and a culture that doesn’t feel like a stretch.

Plus, they make it easy to build networks, invest in local assets, or just enjoy life without feeling like an outsider.

Getting Started: Your 3-Step Plan

Having options is great, but knowing what to do with them is even better. If you’re serious about getting a second passport, don’t let it sit on your someday list.

Here’s how you can start without feeling overwhelmed:

1. Do Your Research

What works for a crypto investor might not work for someone with a global real estate portfolio. So start by narrowing your options based on what matters most to you: mobility, taxes, lifestyle, and investment threshold.

Dig into the details. Don’t just rely on random YouTube videos or outdated blogs. Use official government websites, Citizenship by Investment Program (CIP) portals, and trusted legal advisory sites. Also, keep an eye on platforms like Nomad Capitalist, IMI Daily, and Henley & Partners’ passport index for some solid comparative insights.

Start by listing your top 3 goals and then look for countries that align with those outcomes.

2. Talk to a Professional

Second citizenship is a legal process, not a DIY side project. You’ll need guidance to make sure you’re not just eligible, but protected.

Look for consultants or legal advisors with a solid track record, especially those who’ve worked with other international entrepreneurs or high-value individuals. Many countries have government-approved agents, especially in the Caribbean and the EU. Start there.

A good advisor helps you avoid red flags, streamline paperwork, and plan for taxes and compliance from day one.

3. Prepare Like It’s a Business Deal

Depending on the country, you might need to invest a minimum amount, prove the source of your funds, submit background checks, or stay for a certain period. These things take time, sometimes months. So get your documents in order early. Examples include:

• Passport scans
• Financial statements
• Criminal record checks
• Proof of investment
• Residence or utility bills (yes, some ask for that too)

If you’re aiming for 2025 or 2026 approvals, start preparing now. These programs don’t stay open forever, and regulations can tighten overnight.

The truth is, second citizenship isn’t just a luxury anymore; it’s a smart, strategic move. Whether you’re looking to unlock visa-free travel, reduce your tax exposure, or simply gain the freedom to live life on your own terms, the window of opportunity is wide open. But it won’t stay that way forever.

With how countries are tightening rules and shifting their priorities, waiting might cost you more than money, it could cost you access.

So start now. Build a roadmap. Talk to the right people. Most importantly, don’t just consume information; act on it.
