I'm a tourist and it deterred me. Tired of getting treated like a criminal in immigration office there also - the disrespect is ridiculous.. I'm in Cambodia now.

beer, easier long visa. No wonder tourists are going elsewhere. Sod them.
Because I don't trust advice online, only to be asked for extra documents or to be told its not possible ect. when I try it myself. Very unreliable and often contradicting info. Agents make it so much easier and less likely to screw up.
