US Revokes Brazil Ambassador's Visa

What Happened with Ambassador Viotti's Visa?

The U.S. State Department revoked the visa of Brazil's ambassador to Washington, Maria Luiza Ribeiro Viotti, on Tuesday, August 4. A senior State Department official said the move was a response to Brazil's refusal to approve the agrément for Trump's nominee to Brasília and to Brazil's denial of visas to American diplomats.

How Did Brasília Respond?

Brazil's presidential communications office (Secom) issued a sharp rebuttal, calling the revocation part of a "deliberate escalation of hostile measures" driven by "ideological reasons incompatible with a bilateral partnership always guided by mutual respect." The Palácio do Planalto flatly rejected Washington's two stated justifications, calling them "false."

Is This Part of a Broader Pattern?

Secom's statement explicitly noted that this is not an isolated incident. Individual sanctions imposed by Washington on Brazilian officials — including visa revocations — remain in force, based on what Brazil calls the "unfounded allegation" of political persecution of former President Jair Bolsonaro. Brazil also accused the U.S. of having an "unwarranted interest in interfering in the next presidential election."

Who Is Trump's Nominee and Why Is It Controversial?

The U.S. sent Brazil the formal agrément request for Daniel Perez — Speaker of the Florida House of Representatives and a Trump ally — about a month after the White House publicly announced his nomination. The post has been vacant since early 2025. Brazilian officials were caught off guard: standard diplomatic practice requires the nominating country to consult the host nation privately before making any public announcement. Perez, the son of Cuban immigrants, was nominated at a time when Latin America is gaining prominence in U.S. foreign policy.
