We want to travel from San Pedro, Chile to Uyuni, Bolivia and we do need visa for Bolivia. We don't know whether we can apply it at the frontier. On the safe side, we prefer to apply them in Santiago, Chile. Has any VT members ever applied the visa for Bolivia in Santiago? How long will it take? What are the documents required? I note some comment that yellow fever certificate may not be required if I apply the visa at the frontier. Do I need it if I apply in Santiago? Any advice will be much appreciated.
