The Mexican government has submitted criminal complaints, warned American detention facilities and asked the United Nations to investigate after 17 Mexican nationals reportedly died in U.S. custody or during deportation operations.

Mexico is escalating its legal response to U.S. immigration enforcement by filing criminal complaints over the deaths of Mexican nationals, sending cease-and-desist letters to detention centers and seeking a United Nations investigation into deportation operations.

The Mexican Foreign Ministry said Tuesday that it had begun submitting complaints to state prosecutors in the United States involving citizens who died while in immigration custody or during enforcement actions, according to a report on the government’s intervention.

“Mexico has begun filing criminal complaints with state prosecutors in the United States over the deaths of its citizens in U.S. immigration custody and during enforcement operations,” the ministry said.

The government has also sent cease-and-desist letters to American detention facilities where Mexican nationals died, according to the statement.

The legal intervention follows the reported deaths of 17 Mexican migrants during the detention and deportation process. Mexico is asking the United Nations to examine the circumstances surrounding those cases and the broader conduct of U.S. removal operations.

Mexican President Claudia Sheinbaum presented the effort as a national responsibility rather than a dispute affecting only migrants and their immediate families.

“I don’t think this situation appears acceptable to anyone,” Sheinbaum said Monday. “This is an issue for all Mexicans.”

The government’s actions could complicate U.S. Immigration and Customs Enforcement efforts to detain and return Mexican nationals, particularly if the complaints result in state investigations or legal challenges involving individual detention centers and enforcement personnel.

The information provided did not identify the lawyers assigned to the cases, the states in which complaints were filed or the specific criminal violations Mexico believes may have occurred.

It also did not detail the legal effect of the cease-and-desist letters or explain what changes Mexico is demanding from detention facilities.

The dispute comes as President Donald Trump’s administration pursues an expanded deportation program, pressures Mexico to act against drug cartels and seeks to reduce the movement of illegal drugs and migrants across the southern border.

Supporters of the administration’s enforcement policies argue that Mexico has benefited economically and politically from large-scale migration to the United States while failing to prevent narcotics trafficking and other cross-border crime.

Critics of Mexico’s intervention point to the severe American death toll from illicit drugs transported through the U.S.-Mexico border.

Approximately 70,000 Americans died from drug overdoses in 2025, with much of the mortality attributed to substances entering through Mexico, according to the information provided.

Drug use also left many additional people with serious health consequences, while critics contend that some local governments prioritized policies welcoming illegal migrants without adequately addressing the effects of narcotics trafficking.

An X post discussing the human consequences of the drug crisis was also circulated amid the debate over Mexico’s legal actions.

The United States has a large population with Mexican roots, giving the dispute broad social and economic implications on both sides of the border.

About 37 million Hispanics of Mexican origin lived in the United States in 2021, according to a Pew Research Center study published in 2023.

Advocates of lower immigration levels argue that the growth of that population was encouraged by American business and political interests seeking increased consumer spending, higher real estate demand and a larger labor supply.

Mexico also receives substantial financial benefits from citizens and people of Mexican origin working in the United States.

Migration can reduce domestic pressure on the Mexican government to create employment and finance social programs, while remittances sent by workers in the United States provide a major source of income for Mexican households and the national economy.

Mexico received approximately $62 billion in U.S. remittances during 2025, according to the information provided.

Those financial ties have made U.S. immigration enforcement a significant economic issue for Mexico, in addition to the legal and humanitarian concerns raised by deaths in custody.

The Mexican government is grounding its latest intervention in the treatment of the 17 nationals who reportedly died during U.S. detention or enforcement activity.

Its complaints seek to move the dispute into American state legal systems, while the requested United Nations inquiry would bring international scrutiny to U.S. deportation practices.

The escalation follows several Trump administration actions that have increased pressure on Mexico.

Trump has moved to stop illegal border crossings, reduce narcotics trafficking and compel the Mexican government to intensify operations against its drug cartels. His administration has also halted plans to extend the free-trade arrangement between the United States and Canada in the manner previously contemplated.

Mexico’s legal campaign now adds another source of tension to an already difficult bilateral relationship involving migration, trade, organized crime, remittances and national sovereignty.

Sheinbaum has made clear that her government considers the deaths of Mexican citizens in American custody a matter requiring official action.

The Trump administration, meanwhile, continues to treat deportation and border enforcement as central responsibilities of the federal government.

The outcome may depend on whether U.S. prosecutors accept Mexico’s complaints, whether detention facilities alter their practices and whether the United Nations agrees to examine the 17 deaths and the wider deportation process.
