Americans moving back to the US after failed stints abroad have become common enough that financial advisers coined a name for them, a July 2026 Barron’s report finds: boomerangs. The report builds its case on interviews. It leaves out the harder problem, which is that no US agency counts the return flow at all.

The advisers quoted in the report describe a consistent profile. Returnees struggled to renew visas, couldn’t find stable work, hit bureaucratic walls or moved home for family, most often to care for aging parents or stay close to children.

Mid-career professionals return at higher rates than retirees, who tend to settle abroad for good. Returnees remain a minority of the estimated 5.5 million Americans abroad in 2024, up from 5.4 million a year earlier, in Association of Americans Resident Overseas figures.

No agency counts the return flow

The federal government stopped tracking permanent departures in 1957. It has never tracked permanent returns. Every estimate of the overseas population is a reconstruction from destination-country permits, consular activity and surveys, which is why the stock figures diverge so widely.

AARO says 5.5 million. The State Department has historically used a figure near 9 million. The Federal Voting Assistance Program’s last technical estimate put the overseas civilian population around 4.4 million in 2022.

A return migrant vanishes between those datasets. The person drops off a foreign permit register and reappears in no US administrative series, because arriving citizens clear passport control without generating a migration record. The outflow side at least leaves residue abroad, which is how researchers established that 180,000 Americans emigrated in 2025, the largest outflow in decades. The inflow side leaves nothing.

Eurostat’s emigration tables offer the closest proxy. They record US nationals leaving individual European countries each year, though they can’t distinguish an American returning to Seattle from one relocating to Lisbon.

The visa doors that closed

The returns cluster where the pathways narrowed. Three closures stand out:

• Act XC of 2023. Hungary’s new immigration law took effect in 2024, and new applications for the White Card digital nomad permit were paused during the transition, the report notes. The permit requires around €3,000 ($3,240) in monthly income and doesn’t lead to permanent residency on its own.
• Spain’s golden visa. Madrid closed the property-investment route in April 2025, citing housing pressure. Americans ranked among the program’s largest user groups.
• Mais Habitação. Portugal stripped real estate from its golden visa in October 2023, part of a broader housing backlash that has cooled the reception for Americans in Portugal.

The pattern extends beyond the headline programs. Renewals have become the choke point across European digital nomad visas, where one-year permits force annual contact with systems that keep tightening.

An initial approval no longer predicts a durable legal status. That’s a structural change from the 2021 to 2023 window, when new permit categories opened faster than they closed.

Salaries pull mid-career professionals home

The economics run the same direction as the visa rules. When European universities offered positions to US academics who lost funding in 2025, the posts came with lower pay than the jobs they replaced. The same gap holds across the private sector. US salaries in comparable roles routinely exceed European ones, and the cost-of-living arbitrage that drew remote workers to Lisbon and Budapest has eroded as housing costs climbed in both cities.

The destinations absorbing the largest American communities sit outside Europe anyway. Between 800,000 and 1.6 million Americans live in Mexico, in Mexican and US government estimates, and 10,000 to 15,000 Americans move to Canada each year, Statistics Canada data shows. Those figures anchor the rankings of countries with the most American expats, and neither country reports a return series either.

A return flow measured in anecdotes, not records

The boomerang trend rests on adviser interviews and client counts, not administrative data. That doesn’t make it wrong. It makes it unverifiable at scale, and it will stay that way until either Washington resumes counting citizen migration or destination countries publish permit-expiry data by nationality.

What can be established: the overseas American population grew by roughly 100,000 between 2023 and 2024 in the AARO series, net of every return. Whatever the boomerang count is, the outbound flow still exceeds it.
