Hello! I come to Thailand without a visa Prior and got 30days visa stamp upon arrival, and now the visa is about to expire in 3 days but i would like to stay in Thailand for alittle more for the Loy Krathong. So i was wondering if I can do visa extention? I havnt done that before, and eventuelt what I need for it? What paper? And which immigration office (I stay in Bangkok)? And what do I need to know. Or do i need to do visa run? And eventuelt how people do the visa run here in Thailand? Usually when I stayed in Korea, i just do visa run to Thailand/Japan for a few days, but here when i try to look up there is more different than what I am used to, as there is all sort of bus/train to cambodia and Laos.
Ps: I am a Norwegian citizen
TLDR : Answer Summary
A Norwegian citizen currently on a 30-day visa exemption stamp in Thailand can extend their stay for an additional 30 days by visiting the local immigration office in Bangkok, specifically at IT Square Laksi, and paying a fee of 1900 baht. Required documents for the extension include the TM30 form obtained from your landlord or accommodation, your passport, copies of your passport's first page and entry stamp, a passport-sized photo, and the cash fee. Additionally, as a Norwegian citizen, you are allowed two free visa-exempt entries per calendar year, which can also be extended. If you decide not to extend, a visa run to neighboring countries like Cambodia or Laos is another option, with various transport options available.
