A foreigner traveling to Russia should have a valid passport (expire date should be not earlier than 6 months after the date of visitor's departure from Russia) and an appropriate visa.
To get a visa, a visitor has to submit to a Russian Embassy or Consulate an official letter of invitation authorized by the Russian Ministry for Internal Affairs.
Each participant (and accompanying persons) who needs a visa will timely get such a letter if he (she) sends a completely filled APPLICATION FORM by e-mail to Organizing Committee (email@example.com) as attached file.
We are strongly advice to offer these data to Organizing Committee by June 1, 2017, at the latest. Please, follow these recommendations and apply for a visa as soon possible after receiving an original copy of the invitation to ensure that the visa is issued timely.
