The United States has canceled visas for 18 individuals from Bolivia, Colombia, Ecuador, and Peru, accusing them of undermining democratically elected governments through activities linked to corruption or drug trafficking. The announcement was made on September 28 by the Trump administration, which also warned that 20 more Bolivian citizens would face similar actions. The U.S. Department of State stated that under the Trump administration, corrupt foreign officials would no longer be able to enter the United States freely. The decision was justified by referring to the "commitments" made by the leaders of America's Shield, a coalition formed in February by Donald Trump to fight drug trafficking. This group includes several Latin American countries led by conservative, or right-wing, governments. The individuals targeted in this action are primarily those who are seen as problematic by these local right-wing governments or by American interests. For example, one of those targeted is a businessman suspected of having illegally funded the political party of former left-wing Colombian President Gustavo Petro. Another is a Peruvian judge. This move is part of what has been called a "new offensive" against judges, prosecutors, business leaders, and politicians from Latin America. Critics argue that the U.S. is using its influence to support right-wing governments in the region by targeting those who oppose them. The actions have raised concerns about the use of visa policies as a political tool. The Trump administration has emphasized that the United States will continue to take strong measures against foreign officials who engage in corrupt or illegal activities. This includes those who may challenge the interests of the U.S. or its allies in the region. The administration claims that these actions are necessary to uphold the rule of law and protect democratic institutions abroad.
