The former NSA contractor has not apply for Russian citizenship for now, as he will be able to apply for the Russian citizenship in five years. "A foreign citizen, who got a residence permit, will certainly be able to apply for citizenship," Kucherena said.
Snowden is responsible for handing over material from one of the world's most secretive organisations the NSA. The United States has charged him with the theft of government property and communicating classified information.
Snowden's year-long permit to stay in Russia had already expired on 31 July.
Snowden arrived in Russia on June 23, 2013, on a flight from Hong Kong. According to his lawyer, Snowden will hold a press conference in Russia as soon as it will be possible.
