All international conference participants must possess a passport and other travel documents (hotel reservation and travel insurance) when entering Brazil. Each participant is responsible for his/her travel arrangements and for requesting a visa beforehand, as per the applicable laws. We strongly recommend that all participants check, as soon as possible, the rules for entering Brazil that apply to them. We also recommend requesting visas in the country of origin at least 3 months before traveling.

The Visit Visa (VIVIS) allows for up to 90 days in Brazil and is the recommended visa for attending the conference. Citizens from Mercosul can enter Brazil solely with their photo ID card (physical document/original document), while citizens from other countries must carry a passport. Additionally, Brazil offers visa exemptions to several countries. Please check this information with the Brazilian Embassy/Consulate in your country.
