I will be doing a 3 month trip through South America from June. Visa's aren't a problem on my South African passport, except for Bolivia. I have to get one before I get there, but the visa is only valid for 30 days after it's issued. We leave London in May, and won't be in 1 place long enough to get a visa. Has anyone else had issues with Bolivia visa's? I spoke with the Bolivian embassy, and they said that due to my circumstances, the authorities at the Peru/Bolivia border SHOULD understand, and issue me with a visa.
