Tod is right, you have an Extension of Stay (EOS) permitted until August 31, 2020. you do not have a Non-Imm-O Visa. Technically the same if you leave Thailand and re-enter without a re-entry permit, both a visa or an EOS will become invalid

she should really buy more time (the 7-days extension denied) to get the cancellation paperwork sorted, better safe than sorry

So I guess it is best for her to FLY out of Thailand to a destination where she can get a tourist visa for Thailand. She wrote she wants do go Ranong on the 26th, but this is not an option!

she cannot do a "visa run" in Ranong, just a "border run"

she plans to use the Ranong border with Myanmar. As far as I know you can only do a same-day border run there, not a visa run, as there is no consulate nor embassy nearby and you need to get a 30 day tourist visa for

@Mya****

, in order to proceed to the embassy of Thailand in (?) Rangoon? Being from Serbia i guess she can buy a 15-day visa on arrival when re-entering Thailand

oh, okay! I didn't know that

when issued there is a stamp with the METV saying how long it is "to be used until" date, and this usually is three months from the date of issue. . . . Once you ENTER Thailand, you will get the first 60 days "admitted until" triangular stamp

did you read the note which appears, before you can hit the "apply for visa" which will open a 404 site? Because you must apply in your home country. The note says . . . . "You should apply for a TOURIST VISA from the Royal Thai Embassy or the Royal Thai Consulate-General. With a Tourist visa, you can stay in Thailand for no longer than 60 days. If you wish to stay in Thailand for more than 60 days, you can extend your stay with the Immigration Bureau. APPLY FOR VISA" . . . . .and this means you are not supposed to click onto "apply for visa" - instead, do as the first sentence tells you to do: VISIT an embassy or a consulate, or proceed from out of THEIR websites

they have NOT left Thailand, yet, when they arrive at the domestic section of the airport
