Visa Information

Nationals of some countries will need a travel-visa to enter Brazil. Foreign delegates should contact the Brazilian Embassy or Consulate in their home country as soon as possible to confirm their travel-visa requirements. You can check the requirements for your country here.

For further information, including links to visa regulations and a list of Consulates provided by the ministry of international relations (Itamaraty) in Brazil, please click here. You will also find Frequently Asked Questions here.


Visa-free entry

Citizens from Mercosur member counties (Argentina, Brazil, Paraguay and Uruguay) are not required to present a travel-visa, only their passport or a valid identification document.

Citizens from the European Union and many other countries are also not required to issue a travel-visa, they are only required to present a passport.

NEW! Visa-free entry to Brazil is also now available to citizens of the United States of America, Canada, Australia, and Japan. The measure benefits holders of a valid passport traveling for tourism, business, artistic or sports activities. The initiative also covers travelers transiting through Brazil. Visitors will be granted a stay of up to 90 days, which can be extended once for the same period, as long as they do not exceed 180 days within a 12-month period, counted from the date of the first entry.



We encourage participants from countries that require a visa to apply as early as possible. Visa processing times vary by country.
