DHS Report: 3.89M Emigrated LPRs — Who Falls Under the Tax Treaty Escape Hatch?

By · December 31, 2023 · Updated June 3, 2026

Clear U.S. tax and legal relief now exists for a significant portion of the 3.89 million Lawful Permanent Residents (LPRs) who never formally abandoned their U.S. immigration status. This relief stems from two sources in the law:

(i) Tax treaty laws that apply to individuals residing in one of the 67 income tax treaty countries with the United States, recently including Chile.

(ii) Legal principles, recently confirmed by the Federal Court in Aroeste v. United States, that establish that individuals can apply tax treaty laws (when applicable) even if they missed certain filing deadlines set by the Internal Revenue Service. The Court termed this provision an “escape hatch,” allowing individuals, depending on specific circumstances, to be considered non-residents of the United States (not “United States persons”). This can be true under the relevant treaty, even if they never formally abandoned their LPR status.

The 2023 DHS report estimates that nearly 4 million individuals have emigrated from and left the United States and are now living somewhere around the world. Notably, Mexico constitutes the largest share at about 25% of the total LPR population who have left the United States.

The United States has a total of 59 income tax treaties covering 67 countries. See, Countries with U.S. Income Tax Treaties & Lawful Permanent Residents (“Oops – Did I Expatriate”?) (2014).

The DHS report allows the reader to extrapolate that around 1 million individuals, similar to Mr. Aroeste, are living in Mexico and did not formally abandon their LPR status by filing Form I-407, Record of Abandonment of Lawful Permanent Resident.

Aroeste v. United States is the third case I’ve litigated, examining whether individuals with a “green card” residing outside the United States in a tax treaty country are considered U.S. income tax residents. The previous two cases (involving Mexican and German citizens) didn’t progress to the oral argument stage; as the government conceded both before trial.

How many individuals currently living in Mexico have not officially abandon their LPR status by filing  Form I-407, Record of Abandonment of Lawful Permanent Resident? See an earlier post reflecting different legal consequences to these individuals: Few LPRs Who Leave (Emigrate from) the U.S. Formally Abandon their Immigration Status: Important Tax Consequences (Part I) See notations below from Table 1 and throughout the Full Report here: Estimates of the Lawful Permanent Resident Population in the United States and the Subpopulation Eligible to Naturalize: 2023

A FOIA response yielded surprising information; the government records indicate that only 46,364 Forms I-407 were filed from 2013 to 2015.

What can we glean from the DHS report and the LPR – I-407 information obtained through the FOIA response? There is a substantial gap in the millions; millions of individuals who have physically left the U.S. to reside elsewhere globally, compared to the relatively smaller number of tens of thousands who have officially filed Form I-407, Record of Abandonment of Lawful Permanent Resident.

  • Conclusion

Importantly, now under the legal principles established in Aroeste v. United States, individuals residing in one of the 67 countries covered by an income tax treaty have specific legal relief from the worldwide reporting of income to the United States government.
