巴西政府强烈反对美国国务院撤销巴西驻美大使签证的决定[1]。美方声称巴西拒绝向两名美国官员发放签证，且未接受美总统特朗普提名的驻巴西大使人选，以此作为撤销理由[1]。对此，巴西指控这两项理由均不成立[1]。
巴西政府认为美国的行为违反了《维也纳外交关系公约》[1]。根据该公约，派遣国对使馆馆长人选需获得接受国同意，相关程序属保密事项[1]。巴西指出，美国在未获得巴西正式同意的情况下，就已公开驻巴西大使候选人姓名[1]。巴西拒签的两名美国官员意图质疑巴西选举制度的公正性，试图干涉巴西国内政治进程[1]。
巴西政府声称美方曾以"政治迫害前总统博索纳罗"为由，对巴西多名高级官员实施单边制裁，包括取消赴美签证[1]。巴西要求美方撤销对巴西官员的单边制裁，并指控美国试图干涉巴西内政[1]。
Brazil's government has strongly objected to the United States State Department's decision to revoke the visa of Brazil's ambassador to the United States [1]. The Brazilian government asserts that both justifications offered by Washington for this action are unfounded [1].
The United States cited two reasons for the visa revocation: Brazil's refusal to grant visas to two American officials, and Brazil's non-acceptance of the ambassador candidate nominated by US President Donald Trump [1]. Brazil disputes these claims, arguing that under the Vienna Convention on Diplomatic Relations, the sending country's choice of embassy chief requires the receiving country's consent, and this procedure is confidential in nature [1]. Brazil further points out that the United States publicly disclosed the name of its proposed ambassador to Brazil before obtaining formal Brazilian approval [1].
Regarding the two American officials whose visa applications Brazil rejected, the Brazilian government states they intended to "question the fairness of Brazil's electoral system and attempt to interfere in Brazil's domestic political process" [1]. Brazil accuses the United States of violating the Vienna Convention on Diplomatic Relations and attempting to interfere in Brazilian internal affairs [1]. The government has demanded that Washington revoke its unilateral sanctions against Brazilian officials, noting that the US had previously imposed such measures—including visa cancellations—against multiple senior Brazilian officials on the grounds of "politically persecuting former President Jair Bolsonaro" [1].
