Moscow has criticized the United States over the extradition from Switzerland to the U.S. of a Russian national charged with cyberfraud.
Vladimir Zdorovenin was detained in Zurich in March and sent to the United States earlier this week.
Zdorovenin denies the charges, which include hacking into brokerage accounts and trading third parties' stocks.
Russia's Foreign Ministry says they should have been consulted first before Switzerland sent Zdorovenin to the United States and is demanding Russian consular staff in New York be allowed to meet with the 54-year-old Russian national.
The U.S. State Department says the FBI notified Russia about Zdorovenin's arrest on January 17.
He faces up to life in prison if convicted.
A criminal indictment against Zdorovenin and his son Kirill reportedly charges the pair with hacking into U.S. bank accounts and stealing credit-card numbers, allowing them to steal hundreds of thousands of dollars in 2004 and 2005.
Kirill Zdorovenin remains at-large.
