30 day extension on my 60 day TR visa from uk,.what do I need to provide to Thai immigration ? DIY process,. Is it 2 passport size photos and photo copies of all pages in my uk passport ? I know the fee is 1900 bht,. I’ve got a couple of options, either Kamphaeng Phet immigration office or Chiang mai as I’m taking a trip up there,. I slipped up a bit as I’ve been kicking my heels in BKK for a couple of days and maybe should have gone to wattana, but from what I’ve seen that place can be very busy,. I’ve got untill 25/1/23 untill my 60 days TR visa expires,.
