CIPOA - VI Iberoamerican Conference on Advanced Oxidation Technologies

Visa Information

Brazil adopts a policy of reciprocity regarding visas. This means that nationals of countries that require visas for Brazilian citizens will need a visa to travel to Brazil. According to Brazilian law, Brazil must agree, on a reciprocal basis, to offer visa waiver to nationals of another country, except for the hypotheses established in the Decree 9.731 / 2019. Brazil has signed visa exemption agreements with about 90 countries.

Important Note: The Brazilian visa will never be granted in Brazilian territory. Therefore, it is not possible to obtain your visa in airports, ports of entry or any other point of the Brazilian border.
