I need to get a work visa for Russia. I dont have a thai visa so It seems I cant get a russian visa at the embassy in bkk. I have read on the internet that if you go to cambodia and get a cambodian business visa then you can get the russian visa at the embassy there. Has anyone done this before? What is needed for the cambodian business visa?

$35 for a month, or look there:
