The U.S. government, under Secretary of State Marco Rubio, has imposed visa restrictions and revoked visas for officials from Brazil, Cuba, and several African and Caribbean countries due to their involvement with Cuban medical missions abroad. These actions target Brazilian officials connected to the Mais Médicos program, a collaboration involving Cuba and the Pan American Health Organization (PAHO), which the U.S. accuses of being a form of forced labor and a "diplomatic scam." The U.S. alleges complicity by these officials in the Cuban labor scheme. Brazil has condemned the U.S. measures as unjustified attacks, with Brazilian Health Minister Alexandre Padilha affirming that the Mais Médicos program will continue despite the U.S. sanctions. Cuban Foreign Minister Bruno Rodríguez also rejected the U.S. policy as aggressive. The U.S. actions extend to officials from African nations and the Caribbean island nation of Grenada, with the U.S. characterizing the Cuban medical missions as forced labor. This move follows broader U.S. scrutiny of Cuban overseas labor programs. Additionally, the U.S. has limited visa issuance to Brazilian Supreme Court judge Demoraes, linked to the trial of former President Jair Bolsonaro, reflecting ongoing tensions between the U.S. and Brazil. Humanitarian groups such as Médecins Sans Frontières have criticized the broader U.S. immigration policies under President Donald Trump for their negative impact on migrants.
