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!
