At present, Brazil is neither JAA nor FAA
That's right. Brazil has it's own regulations, based on ICAO annexes and recommendations, of course. If you're intending to do a JAA/FAA course or you already have one, you will need to do all the tests and check flights again to validate your license here in Brazil. You might find more information in the Brazilian Civil Aviation Department:
