Just in case a traveller is misusing the visa-exempt scheme for a longstay, he will get grilled at EVERY Thai land border.
AT EVERY ONE – and that’s a fact!
There is NO EXCEPTION in Nong Khai.
If an officer checks your passport and has all reasons to suspect misuse of their system, you will be asked to answer a few quastions
Just use your brains if you got some:
if your claims were true, then Nong Khai land border would be handled as THE BEST TIPP for multiple and consecutive visa-exempt entries in ALL Thailand related visa groups.
Why is this not happening?
Because your claims are BS
