Visa application requirements for Russia
Students, who go to Russia for study programs or enrolling on a course to a Russian university / school, need to apply for a student visa. When you apply to the consulate for a student visa, you'll need to pay a normal fee, which will be about the same as for a tourist visa ($50-$150, depending on processing time). When you arrive in Russia, you will need to register your visa within the first 72 hours (excluding weekends and holidays) after your arrival.
Please contact the nearest embassy for details.
