Oh wow! Definitely don’t assume the immigration officer knows English. In 6 years of going to Bangkok immigration they barely spoke a word to me except one senior officer once that spoke barely passable English.
I would say go do a 90 day report (if you are here a continuous 90 days) and if you don’t need to do it then they will tell you and you will know what to do for the next 5 years. Alternatively you could ignore it and pay the fine if you get caught.
I'm assuming that is from a list of required documents for a 1 year extension? I never got one of those. I started extending in November, 2018. I learned what to bring from the Thai visa advice FB group.
I did submit a hand drawn map but I'm not sure what a receipt would be. I paid my monthly condo rent with a transfer from my Thai bank. The bank statement would be my evidence.
Whatever . . . if they are different then they are different. I stand corrected.
Interesting. I have an LTR now. My last OA extension was Oct 2022. Like I said, always brought, it never asked. I’ve never heard the requirements to be different.
