Mexico's government announced legal action against the United States over a surge in deaths of Mexican nationals in U.S. immigration custody and during enforcement raids. Officials have also sent cease-anddesist letters to U.S. detention facilities where Mexican nationals have died. Mexican President Claudia Sheinbaum said the issue affects all Mexicans and defended the legal effort as a necessary response to protect her country’s citizens. Mexico is also asking the United Nations to investigate U.S. deportation operations following the reported deaths of 17 Mexican nationals during the deportation process linked to Immigration and Customs Enforcement (ICE).
Additionally, the Mexican government is supporting a historic classaction detainee lawsuit targeting unconstitutional and deadly conditions (e.g., medical neglect, mold, and punitive isolation) at the Adelanto ICE Processing Center.
According to official Mexican figures, at least 177,000 Mexican nationals have been detained in the United States so far this year, and more than 13,000 remain in custody because of their irregular immigration status.
The legal campaign comes as the Trump administration doubles down on its aggressive immigration crusade, including expanded deportations and increased pressure on Mexico to help curb illegal immigration and cartel activity. The dispute adds another point of tension between the neighboring countries as both governments defend sharply different approaches to immigration enforcement and the treatment of migrants.
The disagreement is about more than the individual cases, as Mexico is taking the unusual step of directly challenging U.S. immigration enforcement through legal action. If Mexico continues to pursue legal action and international investigations, the disagreement will likely complicate cooperation.
