Tod Daniels clarification, please. Someone in another group stated: "a VOA is for 15 days only, not extendable, and for 31 listed countries, a visa-exempt, however, gives passport holders of 93 listed countries a 60-day visa exempt stamp which can be extended by 30 days at an immigration office for 1900 baht."..... my understanding is that the "visa-exempt" term is in regards to the status of the countries, and the term "Visa On Arrival or VOA" refers to the 60 days stamp given on arrival to Thailand for those 93 countries. Is this correct or am I mistaken? Thank you.
