Demand for US dual citizenship — a second passport obtained by an American citizen through investment, ancestry, naturalization, or marriage — has reached record levels in 2025 and 2026. Americans now constitute the single largest national group applying for alternative citizenship globally through investment migration programmes, according to Henley & Partners, which reported that US nationals accounted for over 30% of all investment migration applications it received in 2025 — nearly double the combined total of the next five nationalities.
This is a striking reversal. A decade ago, demand for US dual citizenship from Americans was minimal — the US passport was among the world’s most powerful and America was the destination, not the source. Today, the US passport has slipped to 10th place in the global passport rankings, and the drivers pushing Americans toward a second passport are multiple, visible, and accelerating.
Why Are Americans Seeking US Second Citizenship in 2026?
The surge in demand for US second citizenship is not driven by a single factor. Research and survey data from Henley & Partners, Newsweek, Al Jazeera, and CEOWORLD Magazine point to a combination of motivations:
1. The Decline of US Passport Power
The US passport has fallen from 4th place in 2006 to 10th in 2026, with visa-free access to 179 destinations. While still a strong passport, Americans now find themselves behind Singapore, Japan, South Korea, and most EU countries for global mobility. More practically, several countries that previously offered visa-on-arrival or visa-free access to Americans have tightened requirements in recent years in response to US reciprocity policies. A spring 2025 Harris poll found that almost half of all Americans — and two-thirds of Americans aged 18–29 — said they would like to have dual citizenship. The top cited motivation was freedom of travel.
2. Political Uncertainty and Polarisation
The return of Donald Trump to the White House in January 2025, combined with executive orders targeting civil liberties, immigration protections, and minority rights, prompted a sharp acceleration in US second citizenship enquiries. Citizenship advisers reported unprecedented spikes in applications from LGBTQ+ individuals, activists, academics, and anyone with concerns about the direction of domestic policy. Arton Capital reported a 400% increase in US client applications in the first quarter of 2025 compared to the same period in 2024. Latitude Group reported a 1,000% increase in US dual citizenship applications since 2020.
3. Financial and Tax Planning
High-net-worth Americans are increasingly using second citizenship as a component of international tax planning. Countries with no personal income tax — including several Caribbean nations offering citizenship by investment — provide tax advantages for Americans willing to establish genuine residence abroad and renounce US citizenship. For those not willing to renounce, a second citizenship still provides flexibility and a plan B. The CEOWORLD USA Wealth Report 2024–25 found that inquiries from affluent Americans about residency and citizenship-by-investment programmes surged 600% over five years.
4. A “Plan B” Mentality — Not an Exit Plan
Critically, most Americans seeking US second citizenship are not planning to leave the United States. According to Latitude Group, approximately 80% of their US clients seeking a second passport say they have no immediate plans to relocate. They want the option — a safety net that provides freedom of movement and a guaranteed legal right to live elsewhere if domestic circumstances deteriorate significantly. Henley & Partners describes this as “geopolitical arbitrage” — holding optionality across jurisdictions as a hedge against jurisdictional risk.
Is Dual Citizenship Legal for Americans?
Yes — dual citizenship is currently legal in the United States. The US government does not prevent its citizens from holding citizenship in another country, and does not maintain an official registry of dual citizens. Most naturalization applicants from other countries are permitted to retain their original citizenship when they become US citizens, and vice versa.
There is an important caveat: the Exclusive Citizenship Act of 2025, introduced by US Senator Bernie Moreno, would — if enacted — require American citizens to relinquish any additional nationalities within one year. Non-compliance would result in automatic loss of US citizenship. As of early 2026, this bill had not been passed into law, but it signals a political conversation that bears monitoring. If you are considering US dual citizenship, consult a US immigration attorney regarding the current legal position before proceeding.
Routes to US Dual Citizenship: Your Main Options
There are four main routes through which Americans obtain a second citizenship. Each has different timelines, costs, eligibility criteria, and practical implications.
Route 1: Citizenship by Descent (Ancestry)
This is the most accessible route for the many Americans with documented ancestry in another country. The principle is straightforward: if your parent, grandparent (or in some countries, great-grandparent) was a citizen of a foreign country, you may have an automatic right to that citizenship — even if you have never lived there.
| Country | Generations Eligible | Key Conditions | Process |
|---|---|---|---|
| Ireland | Up to grandparent level | Grandparent must have been born in Ireland | Apply through Foreign Births Register; no language or residency requirement |
| Italy | Parent or grandparent (post-March 2025 reform) | Previous rules allowed unlimited generations; now restricted to 2 generations | Apply at Italian consulate; documentation-intensive |
| Germany | Parents or grandparents persecuted by Nazi regime | Special restoration route under Article 116(2) of Basic Law | Apply through German mission abroad |
| Poland | Parents, grandparents, or great-grandparents | Ancestor must have held Polish citizenship; documentation required | Apply through Polish consulate |
| Mexico | At least one parent born in Mexico | Children of Mexican nationals born abroad | Declaration at Mexican consulate; no residency requirement |
| Portugal | Parents or grandparents (with Sephardic Jewish heritage route also available) | Standard route requires parent/grandparent to be Portuguese national | Apply through Portuguese consulate; language test may be required |
Note: Italy sharply restricted its citizenship by descent rules in March 2025, limiting eligibility to those with Italian-born parents or grandparents. This overturned a previous rule allowing unlimited generational descent. Italy’s Constitutional Court had scheduled hearings on the constitutionality of this change — monitor for updates.
It is estimated that 30 million or more Americans may qualify for a second citizenship through ancestry, though the actual figure with the documentation to prove it is significantly lower. If you have any foreign-born grandparents, researching their citizenship is the first step.
Route 2: Citizenship by Investment (CBI)
Citizenship by Investment programmes allow eligible individuals to obtain citizenship in exchange for a qualifying economic contribution — typically a donation to a national development fund or an investment in real estate or government bonds. Processing times range from 2 to 16 months, and the process is often entirely remote.
As of 2026, the main CBI programmes available to Americans include:
| Country / Programme | Minimum Investment | Passport Strength | Processing Time |
|---|---|---|---|
| St Kitts and Nevis | USD 250,000 (fund donation) | Visa-free to 156 destinations | 4–6 months |
| Antigua and Barbuda | USD 230,000 (fund donation) | Visa-free to 151 destinations | 3–6 months |
| Dominica | USD 200,000 (fund donation) | Visa-free to 143 destinations | 3–4 months |
| St Lucia | USD 240,000 (fund donation) | Visa-free to 148 destinations | 3–6 months |
| Grenada | USD 235,000 (fund donation) | Visa-free to 144 destinations + E-2 treaty with USA | 4–6 months |
| Vanuatu | USD 130,000 (fund donation) | Visa-free to 125+ destinations | 2–3 months (fastest available) |
Note: No EU country currently offers citizenship by investment. Malta discontinued its programme in 2025. Caribbean programmes are the primary CBI route. Due diligence is critical — work only with government-licensed agents, and be aware that the US government scrutinises these programmes. The Grenada passport is notable for including E-2 Treaty Investor Visa access to the US, which is not available to most Caribbean passport holders.
Route 3: Residency-by-Investment Followed by Naturalization
For Americans who want a European second citizenship — typically a Portuguese, Greek, Spanish, or Italian passport — the route is through residency by investment followed by naturalization after the required residency period. This is a longer-term commitment (typically 5–10 years) but yields a significantly more powerful passport than most CBI programmes.
Portugal is the top choice for US clients at most investment migration firms — chosen by approximately 50% of American applicants, according to Latitude Group. The Portugal Golden Visa requires a minimum investment of EUR 250,000 and only 7 days per year of physical presence in Portugal. After 5 years of legal residence, investors can apply for permanent residency and, subsequently, citizenship — subject to passing an A2 Portuguese language test and meeting character requirements.
Greece’s Golden Visa programme remains active with a real estate investment option starting at EUR 250,000 in most regions (EUR 800,000 in Athens and other high-demand areas as of 2024 updates). Spanish and Italian programmes offer similar long-term pathways. Each has different physical presence requirements, language conditions, and processing timelines.
Route 4: Naturalization Through Residency and Work
For Americans willing to live and work in another country for an extended period, naturalization through residency is the most organic — and often the most affordable — route. Standard timelines by country:
- Portugal: 5 years of legal residence (standard route); citizenship law change pending that may extend this to 10 years for non-EU applicants
- Germany: 5 years of legal residence (reduced from 8 in 2024 reforms); 3 years with special integration achievements
- Canada: 3 years of physical presence in Canada over the 5 years before applying
- Argentina: 2 years of residence — one of the fastest naturalization timelines in the world
- Ireland: 5 years of reckonable residence
Working and living in another country also requires the appropriate work visa and residence permit for that country.
What Americans Are Choosing in 2026
Survey and advisory firm data from 2025–2026 paints a clear picture of which routes and destinations Americans are prioritising:
| Preferred Option | Share of US Applicants (approx.) | Primary Motivation |
|---|---|---|
| Portugal Golden Visa | ~50% | EU passport pathway; minimal physical presence; stable rule of law |
| Malta CBI (now discontinued) | Was ~25% before 2025 discontinuation | Fastest EU citizenship route previously available |
| Caribbean CBI programmes | ~15% | Speed (2-6 months); lower cost; travel flexibility |
| Ancestry-based citizenship | Significant but untracked | No cost; no investment; right by birth for many Americans |
| Greek / Spanish Golden Visa | Growing | Real estate investment; EU access; lifestyle destination |
Tax Implications of US Dual Citizenship: What You Must Know
Unlike most countries, the United States taxes its citizens on worldwide income regardless of where they live. This means that obtaining a second passport does not reduce your US tax obligations unless you also renounce your US citizenship — a serious and irrevocable decision with its own significant implications.
- If you hold a second citizenship but remain a US citizen, you must file US tax returns annually and comply with FBAR (Report of Foreign Bank and Financial Accounts) requirements for any foreign accounts above USD 10,000.
- Some countries with which the US has double taxation avoidance treaties offer some relief from paying the same tax twice.
- Americans who renounce their citizenship while holding a high net worth may be subject to an exit tax — a deemed sale of all assets on the date of expatriation.
Tax planning for US dual citizenship is complex. Engage a US-qualified tax attorney with international expertise — not just an immigration lawyer — before making any decisions.
Frequently Asked Questions: US Dual Citizenship
Can the US government take away my citizenship for obtaining a second passport?
Under current US law, obtaining foreign citizenship alone does not cause loss of US citizenship. A court ruling (Afroyim v. Rusk, 1967) established that US citizenship can only be lost through a voluntary, intentional act to relinquish it. However, the Exclusive Citizenship Act of 2025, if enacted, would change this. Monitor legislative developments carefully.
Which is the fastest second citizenship available to Americans?
Vanuatu offers citizenship by investment with a processing time of approximately 2 months, making it the fastest currently available programme. Sao Tome and Principe, launched in 2025, processes applications in approximately 2 months as well. Caribbean programmes (St Kitts, Dominica, Antigua) typically take 3–6 months.
Does a second passport allow me to travel without using my US passport?
Yes — dual citizens can travel on either passport. Many Americans with dual citizenship prefer to enter certain countries on a non-US passport to reduce perceptions of political association. However, you must enter and exit the US on your US passport, as US law requires US citizens to use a US passport when entering or leaving the country.
What is the difference between permanent residency and citizenship?
Permanent residency gives you the right to live and work in a country indefinitely, but does not include a passport, voting rights, or the ability to pass the status to children as a birthright. Citizenship includes all of these. For Americans seeking a second passport specifically, citizenship — not just residency — is the end goal.
Is a Caribbean second citizenship worth it if the passport is weaker than the US?
It depends on your motivation. If your goal is expanded visa-free travel globally, a Caribbean passport may add relatively little versus the US passport. However, if your goals are political neutrality while travelling, a plan B for residence if needed, or access to specific markets (Grenada’s E-2 access to the US, for example), the value proposition is different. Each situation is individual.
