US revokes visa of Brazil's ambassador Viotti, sparking diplomatic row
The Trump administration revoked the visa of Brazil’s ambassador to the United States, Maria Luiza Ribeiro Viotti, citing Brazil’s failure to grant agrément to the U.S. nominee Daniel Perez before the Brazilian presidential election. Brazil’s government rejected the justification, saying the action violates the Vienna Convention on Diplomatic Relations and calling the U.S. explanation “false.”
Brazil has indicated the revocation could be reversed if it approves Perez after the October election, but the dispute has already heightened tensions, with both sides warning of reciprocal measures. The row is framed by broader U.S. competition with China for influence in Latin America and raises concerns about possible impacts on trade, security cooperation and upcoming elections.
President Luiz Inácio Lula da Silva has accused the United States of attempting to interfere in Brazil’s electoral process, while U.S. officials maintain the decision reflects Brazil’s “obstacle‑creating” stance toward the ambassadorial appointment.
