U.S. Tourist Visa on entry (need round trip ticket?)
I'm worried about getting my U.S. tourist Visa in Bolivia. I am last minute, so not all my plans are set. I'm flying out tomorrow! I have all documents I should need to get the visa at the port of entry (La Paz), but I don't have a round-trip ticket. Does anyone know if U.S. Airway (or TACA from Lima) will give me problems for not having a visa prior to entry? and do I actually need to get a ticket home?
