I could not get to Thai immigration as Cambodia immigration said I would be denied entry and get a stamp denied entry. O’Smach is a very small crossing and he showed me the up to date info. Very difficult to argue, that why I messaged Giant Ibis hoping for a different answer.
So I made a post on this forum asking about visa’s not to open an argument about rules.
The only real border crossing from Siem Reap for me is O Smach, Poipet is a no go with your own car
