The U.S. government, under Secretary of State Marco Rubio, has revoked or restricted visas for several officials from Brazil, Cuba, African countries, and Caribbean nations, including former Pan American Health Organization (PAHO) officials. These actions target individuals alleged to have ties to a Cuban medical program that dispatches doctors overseas, including Brazil's 'Mais Médicos' program, which currently involves 2,659 Cuban doctors. The U.S. accuses the Cuban medical missions of engaging in forced labor practices. The revocations have affected Brazilian officials Mozart Júlio Tabosa Sales and Alberto Kleiman, among others. The Brazilian government, including Health Minister Alexandre Padilha and President Luiz Inácio Lula da Silva, has condemned the U.S. sanctions as unjustified and provocative, asserting the program's importance and resilience despite U.S. pressure. Cuba's Foreign Minister Bruno Rodríguez also rejected the U.S. measures, labeling them aggressive. The U.S. embassy has additionally issued warnings to pregnant Brazilian women regarding visa issuance, potentially denying visas to those seeking to give birth in the United States. The moves have sparked concern and debate within Brazil, with some viewing the U.S. action as a test of political response. Similar visa restrictions may extend to officials in African countries involved with Cuban medical missions, with Kenyan officials reportedly under scrutiny. The U.S. maintains that these steps are part of efforts to address alleged complicity in what it characterizes as forced labor within the Cuban overseas medical programs.
