What is the temporary registration?
Temporary registration of foreign citizens in Russia is their registration at a section of the Ministry of internal Affairs of the Russian Federation. This procedure is mandatory for all foreign citizens arriving to Russia for a period more than a week. Moreover, you need to register within 7 business days after crossing the Russian border. Each foreigner gets a migration card upon arrival to Russia for this. Border guards mark the date of crossing the border in the migration card.
