We are Ghanaian traveling to Bolivia for Volunteering project.
Does Ghana Citizens need to obtain visas before traveling to Bolivia or Ghana Citizens can get Bolivia Visa upon Arrival at Airport?
---------------
According to the Bolivian Ministry of Foreign Affairs website, citizens of Ghana DO need a visa to enter Bolivia, but are not required to obtain it prior to travel. I suppose that means it will be issued at the airport upon arrival.
Since you are planning to stay under 90 days and since your work is not paid, you would qualify as a tourist. Danish citizens are not required to obtain a tourist visa for Bolivia.
