Russian Immigration laws are very stringent and Indian students travelling on damaged passports are frequently turned back from the airport.
Passport and original certificates are the properties of concerned students and should not be given to either contractors or foreign authorities for safe custody. No one has the authority to confiscate passport and students must always keep their passports with them. Police officials often demand to see the passport, visa and registration. Some students have to leave the country for failing to register within the stipulated period of 3 days. The university concerned or contractor generally takes care of the registration process of foreign students.
