I have received my multi-entry tourist visa and am excited about visiting Russia. I have read that I am required to obtain a migration card upon arrival in Russia, also that I must register my visa with the hotel I am staying at. As far as documents are concerned for the migration card and visa registration; will I need any other documents other then my passport i.e. proof of health insurance etc...? Upon exiting Russia what other documents must I provide to officials other then my passport? Are there any "gotchas" that I should be aware of while in Russia? I have read that entry into Russia can quickly become a bureaucratic nightmare, I would obviously like to avoid that and make my trip as enjoyable as possible.
