The U.S. Department of Justice has transferred 14 Mexican nationals serving drug-related sentences back to their home country, saving American taxpayers more than $4 million in incarceration costs. The prisoner swap, conducted under a decades-old bilateral treaty, represents the 184th such transfer since the agreement was first implemented in 1977.
The transfer, which took place on August 8, 2025, was carried out by the Justice Department’s Office of International Affairs with assistance from the Federal Bureau of Prisons. All 14 inmates had requested to complete their sentences in Mexico, with both governments approving the transfers.
“Friday’s transfer of 14 federal inmates to correctional authorities in Mexico has saved the United States over $4 million by eliminating the need to pay incarceration costs for the 96 years remaining on their combined sentences,” said Acting Assistant Attorney General Matthew R. Galeotti of the Justice Department’s Criminal Division in a statement released Monday.
Long-standing Agreement
The exchange falls under the U.S.-Mexico International Prisoner Transfer Treaty, which was signed in November 1976 and took effect the following year. The treaty established a framework for citizens of either country to serve their prison sentences in their home nations while maintaining the integrity of the original sentences.
Under the agreement, transfers can only occur when the offense is punishable as a crime in both countries. The treaty also includes provisions protecting prisoners’ rights and civil status during the transfer process.
Why would the U.S. want to send prisoners home? Beyond the obvious cost savings, there are humanitarian and practical considerations. The Justice Department has emphasized that the program enhances offender rehabilitation by allowing inmates to serve time closer to family support systems while simultaneously addressing overcrowding in U.S. federal prisons.
This month’s transfer wasn’t an isolated event. A similar repatriation occurred in April 2025, when 13 Mexican nationals convicted of drug distribution were transferred back to their home country to complete their sentences.
Global Program
The transfers are part of the broader International Prisoner Transfer Program, administered by the Justice Department’s Office of International Affairs. The program’s specialized International Prisoner Transfer Unit (IPTU) oversees all treaty-based international prisoner movements.
The initiative allows approved foreign nationals in both federal and state prisons to transfer to their native countries to complete their sentences — but only when the countries involved have established treaty relationships. The United States currently maintains such arrangements with more than 85 countries worldwide.
“The Justice Department will continue such transfers – pursuant to our treaty with Mexico – to reduce incarceration costs and relieve overcrowding in our federal prisons,” Galeotti added.
For the 14 individuals involved in this month’s transfer, the move means serving out their remaining time closer to home. For U.S. taxpayers, it represents a substantial saving — roughly $42,000 per inmate annually, according to recent Bureau of Prisons estimates.
Despite the financial and operational benefits, these transfers remain relatively uncommon compared to the total number of foreign nationals in U.S. custody. Still, as prison costs continue to rise and facilities remain crowded, the Justice Department appears increasingly willing to utilize these longstanding international agreements.
