Brazil requires that US Citizens have flight reservations prior to applying for a tourist visa. Per the suggestions in this question, I have found what I believe to be the most reasonable round-trip, fully-refundable flight into Brazil, from Miami (MIA) to Manaus (MAO).
If I were to purchase this ticket, get my visa, then cancel the ticket in favor of a discounted ticket from, say, Lima to Sao Paulo, would this create any issues with my visa, as my application would have said I was flying to and from different cities?
Would it also be a problem if I ended up entering Brazil a day or two later (if post-visa application prices have changed to make this financially advantageous).
My international travel is limited, but I would expect the visa simply to be valid from X date to Y date, and the ports of entry and exit would be immaterial. But I don't want to make a >US$1000 gamble on this assumption.
