The Trump administration revoked the visa of Brazil’s ambassador to the United States, Maria Luiza Ribeiro Viotti, on Tuesday, August 5, 2026. State Department officials cited a prolonged impasse over ambassadorial nominations and Brazil’s recent denial of visas to two American diplomats ahead of the country’s October presidential election.
Washington’s decision marks a sharp escalation in diplomatic friction between the administration of President Donald Trump and Brazilian President Luiz Inacio Lula da Silva. According to State Department officials speaking on condition of anonymity, Ambassador Viotti’s visa cancellation stops short of formal expulsion. The move is designed as a reciprocal measure following months of friction in Brasilia and Washington.
Reciprocal Retaliation Over Visas and Ambassadorial Stalls
The diplomatic crisis centers on two main disputes: Brazil’s delay in approving Washington’s ambassadorial nominee and the rejection of U.S. personnel. The Trump administration nominated Daniel Perez—a Florida state representative and close ally of Secretary of State Marco Rubio—to serve as the next U.S. ambassador to Brazil on June 1.

State Department representatives maintained that Brazil repeatedly stalled on granting formal diplomatic approval, known as agrément, for Perez. A senior official told reporters that Washington had communicated continually with Brazilian authorities for weeks to resolve the delay.
“Basically we’ve had a situation in which our diplomats were being denied the ability to do routine common work between the two countries, and so you know under these circumstances, with the long delay and no promise of ending the impasse of the agreement, we’ve taken reciprocal action with respect to a Brazilian diplomat here to make the point that it can’t always be one-sided.”
The standoff intensified last month when Brazil announced the denial of visas to Assistant Secretary of State for Democracy, Human Rights and Labor Riley Barnes and Deputy Assistant Secretary Samuel Samson. Brazilian authorities argued that the American officials intended to interfere in the upcoming October 4 presidential election. Washington rejected the characterization entirely, insisting the delegation planned routine discussions concerning election integrity, religious freedom and freedom of expression with government and civil society figures.
Strained Alliances and the October Presidential Race
The diplomatic rupture unfolds against a backdrop of deep political polarization in South America’s largest democracy.
Relations between Brasilia and Washington have grown increasingly fractious under the Trump administration. The Lula administration has condemned these moves as attempts by Washington to sway the October presidential election.
Official Reactions from Brasilia and Washington
The office of President Lula issued a formal statement condemning the revocation of Ambassador Viotti’s visa as an overt hostile action driven by ideological motives.

“Today’s decision is not an isolated incident. It is part of a deliberate escalation of hostile measures against Brazil, motivated by ideological reasons.”

Despite the cancellation of her visa, U.S. officials emphasized that Viotti is not being expelled from the country. According to Reuters reporting, State Department representatives clarified that the diplomat remains in the United States without a visa status, but authorities would quickly restore her credentials if Brasilia grants agrément to Perez. State Department spokespeople maintained that Washington values its relationship with the Brazilian people, stating they hope to return to a normal, productive, and transparent diplomatic footing.
