Hi, i am on a business visa in Brazil (which is extendable for another 3 months). Is it good enough to show up at the Federal Police on the 89 day or even on the 90th day to extend it or does it have to be 4-5 days before the 90th day?
Also, does anyone knows when do the 90 days start counting - when you boarded the plane in you home country or 1 day later when you actually passed through the immigration at the Brazilian airport and received your passport stamp?
