Brazil has a so called “reciprocal” visa situation. If the country you are from makes Brazilians get a visa, then you need to get a visa and pay the same amount. This only seems to apply to countries that are richer than Brazil, poorer countries that allow Brazilians in visa free must get a Visa for Brazil.
