It's important about the duration of the student visa
Visa for trip to Russia for educational purposes can be issued for up to 90 days, or for the entire period of study. In the second case, the period will not exceed one year, but students from Arab countries can extend it.
Note! An educational visa does not entitle you to the employment of citizens in Russia after the completion of the educational process. To do this, it will be necessary to issue a visa to Russia with a specially agreed purpose - a work visa.
