In a sweeping display of diplomatic muscle, the United States has revoked the visas of dozens of foreign nationals—including prominent Mexican politicians and individuals from as far afield as South Africa, Brazil, Paraguay, and Argentina—amid a pair of high-profile crackdowns that have sent ripples across the globe. The twin moves, announced by the US Department of State on October 14, 2025, reflect the Trump administration’s increasingly assertive use of visa policy to advance domestic and international priorities, from combating drug cartels to policing online speech about American political figures.
According to Reuters, more than 50 Mexican politicians and government officials, including many from President Claudia Sheinbaum’s ruling Morena party, have had their US visas revoked in recent weeks. The move, which exceeds previously reported figures, has rocked Mexico’s political establishment—where US travel is often a routine part of official business and personal life. Among those affected is Baja California Governor Marina del Pilar Ávila, who confirmed her visa had been cancelled but categorically denied any ties to organized crime.
“The Trump administration is finding new ways to exert more pressure on Mexico,” observed Tony Wayne, who served as US ambassador to Mexico from 2011 to 2015, in remarks to Reuters. The scale of the revocations, Wayne noted, is unprecedented. While previous US administrations have sometimes wielded visa policy to target individuals suspected of criminal activity, rarely has the tool been deployed so broadly against senior foreign officials.
This mass cancellation is part of a broader, strategic alignment in which US intelligence on drug cartels—including data held by the Drug Enforcement Administration (DEA)—is increasingly used to determine who can enter the United States. The Trump administration has designated certain Mexican cartels as terrorist organizations, meaning that intelligence on their operations and political connections now directly affects visa eligibility. A source familiar with the process told Reuters that this marks a significant escalation in how the US government leverages its intelligence apparatus for immigration control.
In response to questions from Reuters, the US State Department made it clear that “visas, including those held by foreign officials, may be revoked at any time” for “activities that run contrary to America’s national interest.” At the same time, the department signaled a desire to maintain productive relations, saying Washington “looks forward to continuing to advance its bilateral relationship with the Sheinbaum government.”
Yet the diplomatic fallout is hard to ignore. The revocations threaten to undermine US-Mexico cooperation on critical issues such as trade and security, even as President Sheinbaum has worked to strengthen joint anti-cartel operations. Sheinbaum herself has publicly criticized suggestions by Trump administration officials that the US might consider unilateral military action against cartels inside Mexico, calling such proposals a violation of Mexican sovereignty. The message from Washington, however, appears clear: the US will use every tool at its disposal—including visa policy—to pursue its security objectives, regardless of the diplomatic discomfort it may cause.
Meanwhile, on the same day as the news broke about the Mexican visa revocations, the State Department took the unusual step of publicly announcing it had revoked the visas of six foreigners from South Africa, Mexico, Brazil, Paraguay, and Argentina. The reason? Social media posts celebrating—or at least making light of—the assassination of conservative political activist Charlie Kirk, who was shot dead at a rally in September 2025.
“The United States has no obligation to host foreigners who wish death on Americans,” the State Department declared in a post on X (formerly Twitter) on October 14. “The State Department continues to identify visa holders who celebrated the heinous assassination of Charlie Kirk.” The post was accompanied by screenshots of critical remarks from six social media accounts, with usernames partially obscured but nationalities identified.
One Argentine national, for instance, was quoted as saying Kirk “devoted his entire life spreading racist, xenophobic, misogynistic rhetoric” and deserves to “burn in hell.” The State Department’s tweet added, “Visa revoked.” Another post alluded to Kirk being “somewhere hot,” a not-so-subtle reference to religious depictions of hell.
Kirk, who was just 31 at the time of his death, was a cofounder of the conservative Turning Point student organization and was credited with mobilizing young voters for Donald Trump during the 2024 presidential election. His assassination set off a firestorm of commentary across the US political spectrum. President Trump, in a highly symbolic move, posthumously awarded Kirk the Presidential Medal of Freedom on October 14, calling him a “martyr for truth” at a memorial service attended by family and supporters.
The fallout from Kirk’s killing has been dramatic. According to an investigation by The New York Times, more than 145 people have been fired, suspended, or resigned over social media posts or comments about Kirk since his death. The State Department’s actions mark a new frontier in how the US government polices the online speech of foreigners—at least when that speech is seen as celebrating violence against Americans.
US Secretary of State Marco Rubio and Deputy Secretary of State Christopher Landau have both been explicit about the administration’s position. “I have been disgusted to see some on social media praising, rationalising, or making light of the event, and have directed our consular officials to undertake appropriate action,” Landau posted on social media in September. He encouraged users to report such comments from foreigners so the State Department could “protect the American people.”
These moves are part of a tightening of visa scrutiny that began in 2019, when the US began requiring all visa applicants to share their social media handles. In June 2025, the policy was further expanded: student applicants must now make all their social media accounts public for government vetting. This follows a broader crackdown on international students who supported pro-Palestine protests on US campuses, which has led to the revocation of over 6,000 student visas this year alone, according to Fox News. Of those, 200 to 300 were reportedly cancelled due to support for “terrorism” or behavior such as raising funds for Hamas.
For many, these developments raise thorny questions about free speech, due process, and the reach of American power. Supporters of the Trump administration’s approach argue that the US has every right to deny entry to those who threaten its national security or celebrate violence against its citizens. Critics, however, warn of a chilling effect on political expression and worry that the policies could be used to target dissent or punish foreign officials for political reasons.
As the United States continues to wield its visa authority in new and expansive ways, foreign governments, students, and activists alike are left to navigate an ever-shifting landscape—one where a social media post, a political affiliation, or even an unproven suspicion can mean the difference between access and exclusion. The message from Washington is unmistakable: in today’s America, the right to visit is no longer a given, but a privilege subject to the shifting winds of politics and security.
