US Revokes Brazilian Ambassador's Visa in Diplomatic Row Over Nominee

The United States has revoked the visa of Brazil's ambassador to Washington, Maria Luiza Ribeiro Viotti, marking a severe escalation in a deepening diplomatic dispute between the Trump administration and Brazilian President Luiz Inácio Lula da Silva.[1]

The State Department described the move as a "reciprocal action" in response to Brazil withholding formal approval for Daniel Perez, the US ambassadorial nominee to Brasília. Additionally, Washington cited Brazil's refusal last month to issue entry visas to two American diplomats.[2]

The Brazilian government swiftly condemned the visa revocation, calling the US justifications "false." In a statement, Lula's office characterized the decision as a "deliberate escalation of hostile measures" driven by ideological motives rather than standard diplomatic protocol.

The dispute centers heavily on the nomination of Perez, a former Florida House speaker and close ally of Secretary of State Marco Rubio. Trump nominated Perez in June, but Brazil argues that the US violated the Vienna Convention by publicly announcing the choice before securing Brasília's private consent, known as agrément.[1]

Tensions were further inflamed in July when Brazil denied entry to Riley Barnes, the US assistant secretary of state for democracy, human rights, and labor, along with a senior aide. Brazilian officials alleged the delegation intended to cast doubt on the integrity of the country's electronic voting system ahead of the upcoming elections.[1]

The State Department vehemently denied those allegations, stating the diplomats were scheduled for routine meetings to discuss human rights and election integrity. A spokesperson called any insinuation of a plot to undermine the democratic process a "baseless lie."

The diplomatic row is inextricably linked to Brazil's highly polarized presidential election scheduled for October 4. Lula, a leftist incumbent seeking a fourth term, is running against Senator Flávio Bolsonaro, the son of former President Jair Bolsonaro and a prominent political ally of Donald Trump.

Despite the severe diplomatic step, US officials clarified that Ambassador Viotti has not been formally expelled or declared persona non grata. She remains in the United States, but because her visa is canceled, she would be required to reapply if she leaves the country.[2]

The State Department indicated that the visa revocation could be quickly reversed if Brazil takes "appropriate action" and formally accepts Perez's appointment. However, Brazilian officials have signaled that the government intends to delay any decision on the US nominee until after the October election.[1]

The tit-for-tat retaliation underscores a broader deterioration in relations between the two largest economies in the Americas. The diplomatic freeze coincides with recent US tariffs imposed on Brazilian goods and stark ideological clashes over regional policy in Latin America.[1][2]
