Lon Snowden, father of fugitive US intelligence leaker Edward Snowden, has obtained a Russian visa and is visit his son "very soon''.
Mr Snowden told ABC TV in the United States he wanted his son to return home provided the justice system is applied "correctly" in his case.
Edward Snowden has been granted asylum by Russia despite requests from the United States. that he be returned.
"We have visas, we have a date, which we won't disclose right now because of the frenzy," lawyer Bruce Fein said, referring to the planned visit to Moscow.
The BBC reports Edward Snowden arrived in Moscow on 23 June from Hong Kong, after disclosing the extent about a secret US data-gathering programme.
He spent more than five weeks in the transit zone at Sheremetyevo airport in Moscow, which he left last week after having been granted the necessary documents on 1 August.
Mr Fein said he had spoken to Edward Snowden's Russian lawyer, Anatoly Kucherena, who had told him he was safe.
Lon Snowden said that "as a father", he wanted his son to return home, but had concerns over whether he would face a fair trial.
Summit cancelled
The BBC reports the row has had diplomatic consequences, with the United States cancelling a bilateral summit scheduled for September.
Russia's decision to grant Mr Snowden asylum is seen as having worsened already tense relations between the two countries.
Mr Snowden, 30, is a former technical contractor for the US National Security Agency (NSA), who also once worked for the CIA.
In June he leaked documents and details relating to NSA programmes that gather data on telephone calls and emails to the Guardian and Washington Post newspapers.
He fled his home in Hawaii to Hong Kong, and subsequently to Russia. He faces espionage charges in the United States.
