doing some reason.. uhh intuitioning i imagine brazil and portugal might have some sort of a visa-free deal going on in which case llama 4 might actually be right here?
AFAIK Schengen has a common visa policy, so there couldn't be such a deal between Brazil and Portugal. It'd also be extremely surprising if two countries not in a common travel area had a deal where you didn't have to clear customs at all, I suspect that doesn't exist anywhere in the world.
Brazilians don't need a visa for Portugal, France, or any Schengen country. But everybody has to pass through immigration control (at least a passport check even if you don't need a visa) when entering the Schengen zone. My question was which country would that happen in.
