U.S. District Judge William Young in Boston, Massachusetts issued an extraordinary public demand for answers Wednesday after Trump administration lawyers claimed during oral arguments that Mexico has a "standing (unwritten) agreement" to accept 6,000 Cuban nationals deported from the United States. Judge Young wrote in a court order: "What? Can this be true? There's some unwritten deal between the sovereign nations whereby 6,000 Cuban nationals have already been shipped to Mexico? Is this deal secret?" The Department of Homeland Security did not respond to a request for comment from Reuters. NPR has been tracking the Cuba deportation policy in parallel with its coverage of the U.S. oil blockade against Cuba.

The revelation emerged in the context of a broader legal challenge to the Trump administration's "third-country deportation" policy, which involves deporting noncitizens to countries other than their home nations when direct removal is not possible. Cuba has historically refused to accept deportees directly from the United States, making it one of the most challenging nationalities to deport in the U.S. immigration system. By routing Cuban deportees to Mexico under an alleged informal agreement, the administration would have created a de facto removal pipeline without the transparency or legal process that formal deportation agreements typically require.

As of mid-2025, Mexico had reportedly received 6,525 total third-country deportees — suggesting the alleged Cuba-Mexico arrangement, if real, represents a substantial portion of all third-country removals under the Trump administration. Mexico's government has not publicly confirmed or denied the agreement. The administration has used both economic leverage — threatening tariffs — and diplomatic pressure to induce several countries to accept third-country deportees.

NPR covered the story in the context of broader Cuban refugee policy, noting that Cuba remains under the U.S. oil blockade and that the simultaneous pressure — blockade at home, deportation to a third country — puts Cuban migrants in an unusually precarious position. Breitbart covered the court proceeding from the angle of judicial overreach, noting that immigration enforcement agreements between sovereign nations are typically within executive prerogative and questioning Judge Young's authority to demand disclosure of diplomatic negotiations.
