To stimulate tourism during the 2016 Olympic Games to take place in Rio de Janeiro, the Brazilian government decided to unilaterally waive the visa
requirement for citizens of the following countries: Australia, Canada, Japan, and United States, traveling to Brazil as tourists between
June 1st and September 18th, 2016, for a stay up to 90 days:
Travelers will not be required to hold tickets for the Olympic Games to benefit from the visa waiver.
The Brazilian visa system operates under a strict reciprocity policy. That means that with the exception of the four countries above, all citizens from countries which require visas from Brazilians will have to obtain visas to attend the conference. Beware that to attend a scientific conference in Brazil a tourist visa suffices. Source: Consulate General of Brazil
Foreign participants should get in touch with the nearest Brazilian Consulate (click on the map) to find out whether a visa is required.
Here you find the list of nationalities that are exempt from this requirement, see also the official Ministry of Tourism page, that includes the whole of the European Union and Mercosur. Those who do need visa should note that a tourist visa suffices for the conference attendance; for more information about Brazil, visit the official Brazilian Institute of Tourism website.
