MOSCOW A lawyer advising National Security Agency leaker Edward Snowden says his asylum status has not been resolved and that he is going to stay at the Moscow airport for now.
Anatoly Kucherena, who was visiting the American at Moscow's Sheremetyevo airport on Wednesday, said that migration officials are still looking at this asylum request and that this process had been drawn out.
Kucherena said that Snowden is staying in the transit zone "for now" and "intends to stay in Russia, study Russian culture."
The lawyer said has enough money to survive "for some period" of time, but he is not rich. Kucherena also said Snowden won't give interviews now as he fears for his safety, and that he will stay in Russia for the period necessary to get a temporary asylum, and then may think about applying for a citizenship in Russia.
The lawyer did not immediately comment on a Russian news report that said Snowden had received a document earlier Wednesday allowing him to enter Russia from the airport.
The American applied for temporary asylum in Russia last week after his attempts to leave the airport and fly out of Russia were thwarted. The United States wants him sent home to face prosecution for espionage.
In response to the news about Snowden's new immigration documents, the White House said it is "seeking clarity" from Russian authorities about his status.
White House spokesman Jay Carney said Wednesday the Obama administration has made clear to the Russians its desire to see Snowden returned to the U.S. to face espionage charges. Carney also had no updates on how Snowden's status would impact President Barack Obama's plans to travel to Russia in September.
Snowden, who revealed details of the NSA's wide-ranging spying activities targeting data and phone communication, is believed to have been staying at the transit zone of Moscow's Sheremetyevo airport since June 23, when he arrived on a flight from Hong Kong.
Russia's RIA Novosti news agency quoted an unidentified security official as saying that Snowden was given the document Wednesday, allowing him to formally enter Russia.
Anatoly Kucherena, a Russian lawyer advising Snowden, arrived at the airport Wednesday to meet the NSA leaker, but refused to comment before the meeting.
However, he told Russia's Rossiya-24 television that he has brought several books for Snowden to read, including one by Anton Chekhov and Fyodor Dostoyevsky's novel "Crime and Punishment."
The novel is about the mental anguish and moral dilemmas of a poor ex-student who kills a pawnbroker for her cash, and Kucherena said Snowden might find it interesting. But the lawyer added: "I'm not implying he's going through a similar mental anguish."
President Vladimir Putin has said that Snowden can be granted asylum in Russia only if he stops leaking NSA secrets.
A spokeswoman for Russia's Federal Migration Service told The Associated Press on Wednesday that it had no information about the status of Snowden's application for asylum.
Granting Snowden asylum would add new tensions to U.S.-Russian relations already strained by Washington's criticism of Russia's pressure on opposition groups, Moscow's suspicion of U.S. missile-defense plans in Europe, and Russia's resistance to proposed sanctions against the regime of Syrian President Bashar Assad.
