The Brazilian visa system operates under a strict reciprocity policy. That means that all citizens from Canada, Mexico, the United States and other countries that require visas from Brazilians will have to obtain visas to attend the conference.
All foreign participants are strongly advised to check the visa page of the Brazilian Embassy in Washington, USA, in order to determine whether and how to apply for a visa. The list of nationalities that are exempt from this requirement includes the whole of the European Union and Mercosur. Those who do need visas should note that a tourist visa suffices for the conference; visit the tourist visa requirements page for detailed instructions and appropriate forms.

On-line registration is available at IMPA's webpage for the conference. Registration fees are US$50 (or R$90) for post-docs or professors and US$20 (or R$36) for students. Fees are to be paid at the conference site. Unfortunately no credit cards or international checks can be accepted. All participants are encouraged to register in advance and as early as possible so that appropriate arrangements can be made for hotel accommodations. Hotel reservations for the duration of the event may be made through Mrs. Michele Leite (email: micheleleite AT cmoeventos.com.br).
During the conference, complete meals at various prices are available during lunchtime in the IMPA cafeteria. Snack foods and sandwiches are available throughout the day at the Institute.
A cocktail party for participants will be held on Wednesday, June 4th at IMPA.

Participants should plan to arrive at Galeão-Antonio Carlos Jobim International Airport (GIG). See this webpage for information about the airport and its services.
It is suggested that you take a taxi to IMPA or your hotel. We advise you to use the official taxis available at the airport booths before exiting the restricted area just after customs. The cost is about R$80.
See the location page at the IMPA website for a local map. There are many websites that offer general information about Brazil and Rio de Janeiro: its history, culture, and traveler’s tips. You may wish to use the links found in the "Online Travel Guides" section of this page (see below). Exchange rates at the time this announcement went to press were US$1= R$1.78 (Brazilian Real).

The majority of ATMs only accept Brazilian-issued credit and debit cards. The ATMs at the international airport work, sometimes, but if they don't, you should exchange cash for the local currency (reais) at the airport kiosk to get taxi fare. Banks usually give the best rates, however, as in any large, metropolitan world-class city, it is not advisable to carry large amounts of cash on your person.
