As I understand it US citizens need a visa to enter Brasil and are photographed and fingerprinted upon entry, in addition are required to pay the $100 reciprocity fee ( or is it for the visa? ) .
Is that for every entry or is the visa/fee and the photograph/fingerprinting good for a period.
I may have to enter the country twice in an 10 day span in Nov.

Also if I am flying say from BA connecting onward in GRU do I have to go through the above?
Thanks.
