I'm planning to travel around the world starting in the end of July. My first flight is Frankfurt to Rio de Janeiro (via Heathrow) on July 26th. I am a German citizen and I want to enter Brazil without a formal visa. According to Brazilian immigration policy, this is possible for up to 90 days.
However, since I'm planning to leave by land, I do not have an onwards ticket for leaving Brazil. I have already taken a look at Entering Brazil by air, leaving by land, will I be denied entry?, however my situation is somewhat different.
The British Airways ticket that I am going to fly into Brazil with also includes a flight from Santiago de Chile to Auckland on October 26th. This is more than 90 days from the date at which I am going to enter Brazil.
I also have a plane ticket from Antofagasta (CL) to Santiago on October 20th, which is within the 90-day-limit of entering Brazil. However, I'm worried that this evidence of my intent to leave Brazil within the allowed time is too weak for Brazilian border police.
Will the tickets I have purchased be sufficient to convince border police that I intend to leave Brazil within the allotted time or will I still have to buy some other ticket out of Brazil?
Update Everything went well for me last July, the border police just stamped me in and didn't event want to see my plane tickets. Not sure if I was just lucky or if they really don't care that much. Note that this was during the world youth day celebrations in Rio, so they might have been optimizing for immigration throughput...
