Can a Vietnamese citizen apply for a 30-day extension on a visa waiver stamp in Thailand?

@Violet ****

While Tod is most likely correct, some immigration office might not have gotten the message. So my suggestion is, to apply at the most earliest convenience and not wait till last days.

EDIT: so you can consider to try another immigration office. On the other hand, I'm not aware that a "border bounce", aka leaving the country and coming back same day or a few days later would be a problem.

You can do that two times in a calendar year, and the year is closing quickly 😃 already.

there's NO limits for Vietnam passport holders.

"Hong Kong, Malaysian, Indonesian, Laotian, Vietnamese, Singaporean, Macao and Mongolia can do this kind of OUT/IN unlimited times."

Side question: if a guy from Singapore bounces out to Laos and back ... he still has no limits? (FACT: asking for a friend, haha)

Yes

Good to know!
