In February 2025, the Brookings Institution published a data set that should have made front pages but didn't. For the first time since 1935, the United States recorded negative net migration. More people left than arrived. The last time that happened, the country was in the middle of the Great Depression and dust was burying Oklahoma.
A year later, we have the receipts. The Wall Street Journal, drawing on residence permits, foreign home purchases, student enrollments, and tax filings from more than 50 countries, estimates that at least 180,000 American citizens relocated abroad in 2025. Almost every one of the European Union's 27 member states now hosts a record number of U.S. nationals. The State Department has a months-long backlog of citizens requesting renunciation appointments.
This isn't a trend piece. This is a structural shift.
The Numbers Behind the Noise
Start with the demand side. Henley & Partners — the firm that essentially invented the citizenship-by-investment industry — reported a 183% increase in American inquiries between Q1 2024 and Q1 2025. By September 2025, actual applications had climbed 67% over the prior year's record. Americans weren't just browsing. They were filing.
And they weren't a footnote in the data. They were the largest national group, accounting for 30% of all Henley applicants globally. That's a staggering figure for citizens of the world's largest economy — people who, until recently, had no obvious reason to want a second passport.
The destination data tells its own story. Portugal's immigration agency AIMA reported 50% more American residents in 2024 than in 2023. Italy saw applications double over two years. In New Zealand, Americans now account for 40% of all golden visa applicants — a number that would have been unthinkable five years ago. Ireland absorbed 10,000 Americans in 2025 alone, double the prior year. An estimated 40,000 secured Irish passports through ancestry claims.
Even the UK — not exactly known for welcoming immigrants with open arms — saw 8,790 Americans apply for British citizenship in 2025, a 42% jump from the previous record.
What They're Running From
The motivations are more layered than the headlines suggest. A Harris Poll conducted in early 2025 found that nearly half of all American adults had considered or planned to move abroad. Among Gen Z and Millennials, the figure was two-thirds.
When Arton Capital surveyed actual applicants — not daydreamers, but people writing checks — the top motivations were travel freedom (72%), security and stability (58%), healthcare affordability (51%), and tax optimization (44%). That ordering matters. Tax came in fourth. Safety and healthcare beat it.
"The motivations don't break cleanly along partisan lines, which is precisely what makes this interesting. It isn't a political protest. It's a risk assessment."
The WSJ's reporting adds texture. Dozens of expats cited a combination of economics, lifestyle, and what they described as a deteriorating social fabric — affordability, political polarization, violent crime, school shootings. Many named Trump's re-election as a factor, though some had voted for him.
Over 100,000 American students enrolled in foreign universities in 2025, drawn by degrees that cost a fraction of their U.S. equivalents. Nursing homes across the Mexican border are marketing directly to elderly Americans who can't afford domestic care. These aren't wealthy people optimizing their tax exposure. They're middle-class families doing math.
What They're Running Toward
The where is as revealing as the why. The traditional playbook for American expats — retire to Mexico, teach English in Thailand, drink cheap wine in the south of France — has been replaced by something more deliberate.
Portugal remains the gravitational center for Americans seeking EU residency. Its Golden Visa, despite well-documented processing delays, offers a low-presence path to permanent residency and eventual citizenship. The D7 visa, which requires only passive income, has become a favorite of remote workers. Lisbon's historical districts have seen home prices double in five years, driven substantially by American buyers.
Greece has emerged as the dark horse. Ranked first on Henley's Global Residence Program Index for 2026, it offers lower investment thresholds than Portugal, faster processing, and none of AIMA's legendary backlog. For Americans who want Schengen access without the wait, Athens is increasingly the answer.
Panama continues to punch above its weight with Americans — dollar-denominated economy, geographic proximity, the Friendly Nations Visa, and a retiree program that's been refined over decades. Costa Rica draws a different profile: families prioritizing ecological stability, universal healthcare, and the absence of a standing army.
And then there's the outlier that keeps climbing the charts: New Zealand. Remote, politically neutral, ecologically pristine, and running on 85% renewable energy. The fact that 40% of its golden visa applicants are now American says something about what a certain segment of the market is optimizing for — and it isn't the tax rate.
The Exclusive Citizenship Act: Accelerant Disguised as Deterrent
In late 2025, Senator Bernie Moreno of Ohio introduced the Exclusive Citizenship Act (S.3283), which would require all U.S. citizens holding a second nationality to renounce one within a year. Failure to comply would trigger $5,000 fines and mandatory registration. A companion bill — the Disqualifying Dual Loyalty Act — would bar dual citizens from federal employment and security clearances.
The legal consensus is that neither bill will pass. Nothing in current U.S. law prohibits dual citizenship. The Immigration and Nationality Act would require amendment. Constitutional scholars have flagged potential conflicts with the 14th Amendment. UT law professor Elissa Steglich put it plainly: "There really is no good way to police this."
But the bills don't need to become law to have an effect. They've already had one — and it's the opposite of what Moreno intended. Industry sources report that the Exclusive Citizenship Act has paradoxically accelerated applications. The logic is straightforward: if there's even a remote chance that the window closes, better to secure a second passport now while you still can. The threat of restriction is functioning as a marketing campaign for the investment migration industry.
This is consistent with a pattern we've seen in other jurisdictions. When Portugal announced changes to its Golden Visa in 2023, applications surged in the months before implementation. When the UK ended its Tier 1 Investor Visa, the final quarter saw record filings. Scarcity — real or perceived — drives action.
The Passport Itself Is Weakening
There's a quieter dimension to the American exodus that rarely gets discussed: the U.S. passport isn't what it used to be.
In the 2026 Henley Passport Index, the American passport ranked 10th — behind 38 countries, including Malaysia, Lithuania, Iceland, Slovakia, Canada, and the UAE. The prior year it had hit 12th, its lowest position in history, after two decades of consistent top-ten placement.
Over the past year alone, the U.S. lost visa-free access to seven countries. Brazil reintroduced visa requirements for American travelers in direct reciprocity for U.S. restrictions — a pointed rebuke that signals how the rest of the world is recalibrating its relationship with American mobility.
For high-net-worth individuals accustomed to frictionless global access, this erosion is more than symbolic. A Caribbean passport from St. Kitts or Grenada now offers visa-free access to countries that require Americans to apply in advance. A Portuguese passport opens 184 destinations. The math is no longer abstract.
The Scale We Don't See
The U.S. government doesn't track dual citizenship. Unofficial estimates range from 7 to 10 million Americans holding a second nationality — roughly 2-3% of the population. According to the MACIMIDE Global Expatriate Dual Citizenship Dataset maintained by Maastricht University, up to 30 million U.S. citizens may be eligible for ancestry-based passports in other countries, though obtaining them requires navigating increasingly complex documentation requirements.
These numbers matter because they suggest the visible exodus — the 180,000 who physically moved, the applicants showing up in Henley's data — is the tip of a much larger iceberg. Millions of Americans are quietly assembling optionality. They may never leave. But they want the option.
Seventy-five percent of countries worldwide now permit dual citizenship. The United States is increasingly out of step with a global norm that treats multiple nationalities as unremarkable. The Exclusive Citizenship Act, whatever its political merits, reads as an attempt to close a door that most of the developed world propped open decades ago.
Bottom Line
The American exodus of 2025-2026 isn't primarily about politics, though politics accelerated it. It isn't primarily about taxes, though taxes are part of the calculation. It's about a generation of Americans — across income levels, across political affiliations — concluding that a single-passport life in a single jurisdiction is an unnecessary concentration of risk. The data is unambiguous: negative net migration for the first time in 90 years, record applications across every major residency and citizenship program, a passport losing ground in global rankings, and proposed legislation that's driving more applications rather than fewer. For those considering their options, the window of maximum flexibility is now. Programs are tightening due diligence, raising investment thresholds, and in some cases closing entirely. The Americans who moved in 2025 didn't wait for permission. They did the math.
