The law extends the deadline for acquiring Russian citizenship for former Soviet citizens who have been legal residents of Russia until 2008.
It also removes a June 2002 deadline for obtaining a residence permit as a required step toward citizenship, and also removes a requirement for knowing the Russian language.
The Russian parliament passed the bill last month.
