I know that to visit Russia it requires an invitation and a Visa.
But I am only changing planes in Moscow. I started to assume that no paperwork would be required, but I could use some information from someone who knows.
I will be flying into DME, I will have about 2 hours between flights (flying in on Siberian Airlines, flying out on United). I do not have to change airports.
Are there any Visa requirements just to change planes in Moscow?
