No progress has been made so far regarding former CIA employee Edward Snowden's request for temporary asylum in Russia, director of the Russian Federal Migration Service Konstantin Romodanovsky told journalists in Moscow on Tuesday.

"I have nothing new to say. Routine work is under way," he said.

"This situation is not exclusive to us in any way. The only exclusive thing is that you are asking very many questions," Romodanovsky said.

"I do not know how officials of my territorial branch work. The central office is not responsible for it. I will learn something new just a little earlier than you," he said.

Snowden fled to Hong Kong in May 2013 and then released classified information regarding U.S. special services' online surveillance activities. Following this, Snowden traveled to Moscow and has been in the transit area of Moscow's Sheremetyevo Airport since June 23. The United States revoked Snowden's passport and is seeking his extradition.

Snowden has officially applied for temporary asylum in Russia. Venezuela, Bolivia and Nicaragua earlier declared their consent to grant him asylum.
