Visa Information

The need for a visa to enter Brazil is a crucial aspect to be considered by foreign travelers. Therefore, it is essential to keep track of relevant information about Brazilian visas, the existing types, and the documents required to obtain them. Understanding the changes happening when obtaining a visa to visit Brazil is a fundamental point. A recent change worth highlighting is the option to obtain a visa digitally, starting from April 10, 2024, for people coming from Canada, the United States, and Australia to Brazil. Furthermore, since December 1st of the previous year, there is a platform available for those with these nationalities, where it is possible to issue electronic visas, also known as e-Visas.

Which countries need a visa to visit Brazil?

Brazil has a reciprocity policy regarding visas. In other words, the visa requirements to visit Brazil are based on the requirements imposed on Brazilian citizens in other countries. Thus, the need for a visa to enter Brazil varies according to the traveler's nationality. For example, citizens of Canada, USA, and Australia have the possibility to obtain a digital visa, which comes from the end of the document exemption. Other nations also require visas to enter Brazil, such as Afghanistan, China, Cuba, Egypt, and a few more.

Therefore, it is of fundamental importance to contact the relevant authorities well in advance to clarify doubts about the visa requirement and issuance for traveling to Brazil.

Who does not need a visa to enter Brazil?

There are several countries that do not need a visa to visit Brazil, which ends up facilitating tourism and travel for their citizens. The list includes a variety of nations, with some highlights such as the MERCOSUR countries (Argentina, Paraguay, Uruguay, and Venezuela), which have free movement agreements with Brazil due to regional integration. In addition to these, others that do not require a visa include Portugal, France, Hong Kong, Ireland, Italy, Peru, South Africa, the United Kingdom, and many others. This policy aims to promote ease of movement and encourage tourism and international relations with these nations.
