Attendees are responsible for determining their specific country entry requirements for Brazil. We urge you to begin the process at least six months prior to the conference.

Attendees are strongly advised to ensure they fulfil all legal requirements for entering Brazil. In addition to a valid passport, an entry visa and invitation letter may also be required. We strongly suggest that our international attendees and exhibitors obtain a business visa to make your entry into Brazil easier.

US attendees can visit the Brazilian Consulate-General in Houston or Washington D.C. for complete entry requirements. Other international attendees can contact their local Brazilian Consulate.

Designed to help participants to meet administrative requirements in certain countries, official letters of invitation for entry visa or other purposes will be supplied upon request through Please allow sufficient time for this procedure and do not forget to send your passport information for the letter.

Please be advised that the invitation letters will only be issued by the GAP 2016 after the participant registers. Therefore, you should fill out the registration form as early as possible in order to get your visa in time for the event.
