As the title states.... I'm experiencing a hurdle at the Cambodia embassy in DC. They are requesting an invitation letter from an entity within Cambodia. Is this new? I have watched many videos on YouTube about the simplicity of obtaining a E visa, but none of these videos mention an invitation letter. The embassy is also asking for $40 for a 30 day E visa. I'm planning on teaching English in Cambodia, but the jobs have to be applied for in person. Can someone please help?
