Is that a typo "can imagine"? You meant "can't", no? Yes, proof of onward flight. How about 20,000 THB in cash too? Seems they are tightening the screws these days and finding ways to refuse people.
Yes, I have stayed between 4 and 6 months every year except during Covid. Hopefully that is still considered OK.
I'm just trying to understand the conditions where using border bounce and safe entry companies becomes advisable. Of course, if you've been here for a long time (more than 6 months) with many consecutive visa exempt entries. And they would also facilitate same day re-entry for VE on land borders. If you stay 2 or more days in Laos, then that makes the border bounce minivan companies unnecessary?
Thanks again for your advice. You're an all-star.
