Resident registration in Russia

Russia has a system called the 'Resident Registration System'. This means that everyone who lives in Russia has to register where they are living when they arrive in the country and then make sure to keep their information up to date. This helps the government keep track of who is living in Russia and make sure that people are following the rules. It also helps to keep people safe by having important information about who is living in the country.
