Just got grilled on my way back from Poipet Cambodia border back to Thailand.
They took a glance at my passport and immediately pointed me to the screening desk.
I m on my 3rd multiple entry in a period of 2 years on and off travel to thailand from Europe.
He said however flying in with this type of visa would be no problem but isn’t meant for land borders.
I had sufficient funds with me plus confirmed flight out and still was being very persistent of sending me back to Combodia.
After calling the misses i was allowed to pass but was advised to fly in in the future.
So i think i will skip this border as entry point in the future.
