How to Pay the Argentina Visa Fee Online
Citizens of the United States, Australia and Canada must possess a passport to travel to Argentina. If they intend to travel to Argentina as tourists or on business, for a period less than 90 days, they are exempted from asking for a visa. However, they do have to pay the Argentina Reciprocity fee, which isn't different from what Argentine citizens have to pay for travelling to US, Canada or Australia. (Hence the name "Reciprocity")
