A valid passport is required to travel to Brazil. We recommend applying for one as soon as possible if you do not have it yet, as passports often take a while to be processed.
Please visit the Brazilian Tourism Office for a list of countries whose citizens need a visa. For further information about visa application requirements, contact your travel agent and/or a local Brazilian Consulate office. For U.S. and Canadian citizens a visa is required, please visit the Brazilian Embassy website in Washington. For an invitation letter for visa purpose, please register with the conference and e-mail a request form to the CCGrid07 registration chair (firstname.lastname@example.org).
Rio's international airport has excellent access to Rio's south zone where most of the major hotels are located. The airport is served by 28 international carriers as well as the three major Brazilian airlines and between them they offer direct flights to-and-from more than 80 international cities and most of the major Brazilian centers of population. A shuttle service operates between Rio and São Paulo and is based at Rio's smaller city center airport, Santos Dumont. An efficient taxi and bus service links the international airport with the main hotels and residential areas.
