Surprise
Im very surprised that foreigners, excluding malaysians, are only allowed to enter Thailand via land, 2 times per year. No limit if entering by air.
At the poipet-aranyapratek crossings, when exiting cambodia, the cambodian immigration officer refused to stamp my passport because I have entered thailand via this land crossings more then 2 times.
I was therefore forced to engage illegal agents to help me exit poipet and enter Aranyapratek, this arrangement cost me 1400 baht.
