A valid passport and, in some cases, a visa is required to travel to Brazil to citizens of countries that impose the same restriction to Brazilian citizens.
Please check here for a list of countries whose citizens do not need a visa to travel to Brazil.
If your country does not have a visa exemption, in particular if you are
from US, Canada, China, India and others, please visit
the Brazilian Embassy website in Washington, D.C., for more information on how to apply for one.
Note that for scientists, professors or researchers attending cultural, technological or scientific conferences, seminars, a tourist visa is required.
In this case, an invitation letter must be submitted.
Information on how to get an invitation letter is available here.
Note also that the brazilian embassies in US have assigned jurisdictions, in terms of geographical area covered. A specific embassy only processes visa applications submitted by visa service agencies for applicants who reside inside its assigned jurisdiction. Applicants who reside outside an embassy jurisdiction can still apply at its section by coming in person to it. Specific embassy jurisdictions can be found at here.
For further information about visa application requirements, contact your travel agent or a local Brazilian Consulate office.
You can also check the information available at the Brazilian Tourism Portal.
