Yeah, I'm still here. I can help you out with visa questions when I get home in a couple of weeks...Can you wait that long or were you hoping to come sooner? Anything is possible here, and so far on this trip I've met about 15 non-Iranian Americans, all of whom have enjoyed themselves immensely.
Still in Tehran? I'd like to go. Can you point me to a resource that explains what an American needs to do to get a visa? I've heard conflicting information - probably because the regulations keep changing with the politics.
If you ever make concrete plans for a trip to Cambodia, I'd be happy to give you some advice in return.
