Leaving America for Europe? The Green Card Is Not Something You Just Walk Away From

A family in Los Angeles decides it is time. Fifteen years in America, a green card each, and a plan: Düsseldorf — closer to family, a European chapter. They book the flights, convinced the hard part is the move itself. Then one question changes the shape of everything: "How many years have you held that green card?"

Leaving the country is not leaving the system

The United States taxes its citizens and green-card holders on worldwide income — wherever they live. Moving to Germany changes your address, not your status. Until the card is formally resolved, the U.S. filing obligations continue; and from the day you establish residence, Germany taxes your worldwide income too. Two systems, one life, at the same time.

The eight-year line few have heard of

Hold a green card in 8 of the last 15 years — any part of a year counts — and you are a "long-term resident." Surrendering the card is then treated, for tax purposes, like renouncing citizenship. Meet any covered-expatriate test — net worth of $2 million or more, an average annual U.S. tax bill above $211,000 (2026), or failure to certify five years of compliance on Form 8854 — and the IRS deems your worldwide assets sold the day before you exit. Gains above $910,000 (2026) are taxed. The departure itself becomes the taxable event.

2026 made leaving cheaper — not simpler

This spring, the fee to renounce U.S. citizenship fell from $2,350 to $450, and interest surged. But the fee was never the real cost. The exit-tax rules did not move — cheaper paperwork simply brings more people, sooner, to the same hard questions.

The Iranian layer underneath

For Iranian-Americans, one more dimension. While you are a U.S. person, dealings with property in Iran run through OFAC's narrow general licence (31 CFR 560.543): selling property you inherited or owned before becoming a U.S. person and moving the proceeds to the U.S. — under conditions. Property received as a lifetime gift while already a U.S. person generally falls outside it and may need a specific licence. And on arrival, the German side tests the same asset again — source of funds, documentation, provenance. Same property; a different language of proof.

You can change countries in a day. Changing systems takes a structure: the U.S. exit resolved properly, the Iranian dimension documented, the German landing prepared — sequenced before the flight, not after. One legal system is never enough. Neither is one departure.
