"He does not intend to return to the United States until all criminal prosecution against him is terminated", Kucherena said.
The lawyer went on to say that Snowden's health is fine and that "he tries to be self-isolating", and avoids public places as much as possible during the pandemic.
A day prior, Kucherena revealed that Snowden had received a permanent residence permit in Russia.
Snowden, formerly an intelligence contractor, has been living in Russia since 2013. He fled the United States after leaking classified documents showing that the National Security Agency was collecting the telephone records of millions of US citizens. He is wanted in the United States on espionage charges.
