Electronic visitor visa
Travellers need a visa to visit Russia for Business or Tourism. An eVisa is the fastest and easiest way of obtaining a visa for Russia because travellers can submit their applications and supporting documents online. Once the application is approved, travellers receive their eVisa confirmation electronically. A valid visa is required to board the flight. If the visa is expired or doesn’t match the traveller’s passport information, travellers will not be able to board their flight. Entry to Russia with an eVisa is supported at select airports.
