I'm trying to navigate the process for a non O and have contacted some agents and several are from Pattaya and I'm in Bangkok, and then I received message from one who says the paperwork must be done in province where one resides.
I'm at a hotel that's been here since 1952 but they dont seem to know about tm 30. Tried to navigate the immigration page but can't get past captcha.
I've done my previous extension myself in Chiang Mai.
