For my recent trip to Brazil, I knew that as a US Citizen, I needed to get a visa. The only person going on the trip who was exempt from this requirement was my friend who was a Singaporean citizen.
I looked up the requirements. The fee for the visa was $160, payable in USPS Money Order. Due to a new reciprocal agreement, it would be valid for 10 years with multiple entries allowed. It was still 6 weeks out from my trip, I had plenty of time, right?
