Transit Visas: If you intend to transit through Russia by land en route to a third country, you must have a Russian transit visa issued by a Russian Embassy or Consulate. If you are transiting through an international airport in Russia, and will depart from there again in 24 hours to an onward international destination, without leaving the customs zone, Russian law does not require you to have a transit visa. However, this law is sometimes misinterpreted by travelers and customs officials alike, and we recommend you obtain a Russian transit visa if there is any doubt about your transit plans. Foreigners who arrive in Russia without a valid visa, who do not meet visa-free transit requirements, may be forced to return to the point of origin at their own expense.
