Markit wroteMost, if not all, countries have a VOA the only difference is the passport holder that is allowed to get it. For instance America has a VOA for all Europeans but try walking in if you come with an Asian passport
So Indonesia allows me to hop on a plane, walk to Immigration, pay $35US and have a holiday(Australian). After checking America VOA, I have to APPLY FOR ESTA, pay $14US, have a passport with chip, wait for my ESTA to be approved, then hop on a plane.
This is Visa wavier program which is only for 90 days for countries listed.
American VOA??????
