As of 25 November 2002, all foreigners are obliged to fill in a migration card, which will be given to them the instant they cross the Russian border.
It is required to put in the migration card: 1) personal information, 2) terms of stay in Russia and the purposes of the visit and 3) the prospective residential address. It is obligatory to fill in the name of the inviting company and the address of the inviting company. Everyone, who has not put a registration mark due to the address of prospective stay of residence within three days (in other words, visa registration), will be considered illegal. The card should be handed over to immigration officials on the border when leaving the country.
