I thought i would post this and be as brief as possible. i am not new to thailand. i have been traveling here for 16yrs and lived here for 2yrs 2015-2017. probably 10 times over this time frame.
in august 2024 i obtained a 60-day tourist visa via the thai embassy online in the US (a week later they changed the regulation tha this is not needed). i entered thailand and extended my 60day visa for 30days.
exited, on time-on november 1st and spend about 20 days in cambodia via flight. upon arrival, 2 days ago at DMK ariport a very young (25yoa if that) immigration officer read me the riot act, of sort about "i cannot do this" and "i must get a O visa" ect.
i told her i was here for medical care and had both emails and paper copy;'s of such for bangkok hospital. she did not ask to see them, though.
she initially asked for my onward ticket of which i usually "have" one ready. this time i did not thinking nobody asks for that. she DID.
anyways i will sort this out with immigration and/or get the O or other extended visa. moral of the story:
"IF" i had my onward ticket (or rented one, per se) the immigration officer i believe would not of gone into her rant. there was a female supervisor sitting behind her i believe she was new and wanted to make "a" name for herself.
as i am not aware on a tourist visa if you leave there is a specified amount of time you need to stay out before coming back. then again thai immigration. like any nation's immigration can say, do whatever they want.
IF i had an onward ticket i believe i would not have had to listen to her lecture. just FYI.
