@Stuart ********
hi stuart. I will try to provide as many details as possible. I entered during covid, I m on my 4th year through extensions, my current extension expires next february 2025. Before exiting 2 months ago i checked many times with pattaya immigration and visa agencies, according to them (meaning the stamp in thai on my passport, the one that you mention) this stamp has at the bottom a sentence in thai which says i need to have health insurance.
