Brazil denounces revocation of ambassador's visa by the US

On August 4, 2026, the Brazilian government repudiated the United States' decision to revoke the visa of Ambassador Maria Luiza Ribeiro Viotti, who was serving in Washington. The measure was announced by the U.S. State Department on the same day.

Revocation of the ambassador's visa

Brazil's ambassador to the United States had her visa altered, according to an official communiqué from the State Department. The Brazilian government classified the two justifications presented by the United States as false.

U.S. justification

The United States argued that the revocation resulted from Brazil's delay in responding to the diplomatic approval of the Trump administration's nominee to assume the U.S. embassy in Brazil.

Accusations of Vienna Convention violation

According to a note from the Presidency's Communication Secretariat, the disclosure of the nominee's name before the host country's consent was granted violated the Vienna Convention on Diplomatic Relations. The text emphasizes that the convention does not set a deadline for granting agrément.

Alleged electoral interference

The Brazilian government also cited the denial to two U.S. officials, alleging that the presence of these agents was intended to cast doubt on Brazil's electoral system and interfere in the upcoming presidential election.

Context of sanctions and diplomatic efforts

It was recalled that Brazilian officials are still under Magnitsky Act sanctions imposed by the United States in retaliation for Jair Bolsonaro's conviction for a coup d'état. President Luiz Inácio Lula da Silva, who visited Washington in May, asked President Trump to lift the individual sanctions, highlighting that Brazil has spared no effort to resolve the differences and that the episode is part of a deliberate escalation of hostile measures driven by ideological reasons incompatible with the bilateral partnership.
