Most foreign business visitors need a visa or eVisa to enter Brazil unless they hold a passport from a visa-exempt country. Brazil's Ministry of Foreign Affairs runs both a consular visitor visa (VIVIS) and an electronic visitor visa (eVisa) for eligible nationalities such as U.S., Canadian and Australian citizens. Check your nationality on the gov.br pages before booking travel.
Applications for the Brazilian eVisa are submitted online; consular visitor visas are handled through the Ministry of Foreign Affairs integrated system and the nearest Brazilian consulate. The event organiser does not issue invitation letters on this evidence - confirm business visitor documentation with your local Brazilian embassy or consulate.
