The visa policy of Russia deals with the requirements which a foreign national wishing to enter the Russian Federation must meet to obtain a visa, which is a permit to travel to, enter, and remain in the country. Visa exemptions are based on bilateral or multilateral agreements. Russia has agreements with scores of countries whose citizens are either exempt from visas or can apply for a visa online (e-visa). Citizens of countries without such an agreement with Russia must obtain a visa in advance from a Russian diplomatic mission or visa centre.
Foreign citizens while in the territory of Russia, must comply with the legislation of Russia, including requirements of customs, border and immigration regimes, rules of travel finance, registration, internal movement within the territory of Russia and extensions of stay.
Nothing limits the right of competent authorities of Russia to deny entry or to shorten the period of stay in the territory of Russia for foreign citizens.
