I got a Single Entry Tourist Visa for Thailand back in January. I prolonged this Visa at Thai Immigration for 30 days. After that i got another 30 days doing a border run to Myanmar. End of this month i am planning to fly to Vietnam for a few days. When i get back from Vietnam to Thailand, do i automatically have another 30 days in Thailand? And is it possible to prolong this visa doing another border run to Myanmar?
Thanks in advance for your answers/suggestions!
TLDR : Answer Summary
The user inquired about the validity of their Single Entry Tourist Visa upon returning to Thailand from Vietnam after multiple extensions and border runs. Comments suggest that flying back may grant an additional 30 days under the visa waiver, though there could be limitations on repeated entries. Some also recommend obtaining a new tourist visa from Vietnam for a longer stay.
