Doubt that will fly in the current situation. I had been gone for more than 3 months and they pulled me out at BKK and yak yak at me about time being spent in Thailand.
The woman said 180 days, I asked where it says that. Can't show it because they make it up as they go. Eventually they stamped me in, immigration at Jontiem said nothing when I got a 30 day extension.
it's not a visa on arrival, it is an exemption. A visa on arrival (VoA) only applies to certain countries who don't qualify for the 60 day exemption. You CAN apply in advance for a 60 day tourist visa through their e-visa portal much like you do the 90 day Vietnam visa. The 60 day exemption can be extended another 30 days by going to immigration and paying 1900 baht.
just saying that the 65,000k a month option is viable, not sure why they say it's so much extra paperwork that would be worth wasting 32-40k a year in lost interest
saw the extension denied in Chonburi for this exact reason. They told the guy he had to leave the country and come back and apply for a fresh visa again.
