Effective 26 August 2024, individuals who require a visa to enter Brazil based on their nationality (i.e., visa nationals) must obtain an entry visa prior to transiting through the country. This change impacts all visa nationals transiting through Brazil, irrespective of the duration of their transit through the country. These individuals may apply for a visa at a Brazilian consulate abroad. Previously, these individuals could transit through Brazil without obtaining a visa provided they did not leave the airport transit area.
