I was admitted to Brazil 5 times under an allegedly expired visa. I had no way of knowing it was expired, it’s not specified anywhere on the visa or in any Brazilian embassy/travel advisory site. But on the 6th time after it had expired, I finally hit an immigration agent who cared enough to turn me away or understand that it was expired. So this really tracks.
