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?
