I believe everything has to be in Portuguese. I just went to the procedure myself. It has gotten a lot better over the years but if you can, try to avoid DAC in Sao Paulo. They are waaaay to slow. You will also need to get your medical done here. Again try to avoid Sao Paulo if you can. The written test was easy. Mostly regulations. The flight test was a joke compared to FAA standards but then again I already have over 2500 hours. I hope this helps.
