"If I could go anywhere in the world, that place would be home," Snowden said almost a year to the day since he revealed a stunning US surveillance dragnet mining data from phones and Internet companies around the world, including Europe.
"From day one, I said I'm doing this to serve my country. Whether amnesty or clemency is a possibility, that's for the public to decide," he told NBC in his first interview with US television since the scandal broke in early June last year.
And he sought to defend himself against charges led by the US administration that he is a hacker and a traitor who endangered lives by revealing the extent of the NSA spying program through the British daily The Guardian.
"The reality is the situation determined that this needed to be told to the public. You know, the Constitution of the United States has been violated on a massive scale," he said.
"How can it be said that this harmed the country when all three branches of government have made reforms as a result?" Snowden asked, looking relaxed and calm during the interview in a Moscow hotel.
But top US officials laughed off the idea of a clemency. Secretary of State John Kerry said the 30-year-old former CIA employee should "man up" and return to face trial.
Snowden also alleged he was not just a low-level contractor working for the CIA, as the White House has repeatedly insisted.
"I was trained as a spy in sort of the traditional sense of the word in that I lived and worked undercover overseas - pretending to work in a job that I'm not - and even being assigned a name that was not mine," he told NBC.
Snowden said he had worked covertly as "a technical expert" for the Central Intelligence Agency and the National Security Agency (NSA).
But National Security Advisor Susan Rice disputed his contention, replying "no" when asked by CNN if he had been a highly-trained undercover spy.
Snowden however blamed the United States for forcing him into exile in Russia.
"The reality is, I never intended to end up in Russia," he said in the interview recorded clandestinely last week in Moscow.
"I had a flight booked to Cuba onwards to Latin America and I was stopped because the United States government decided to revoke my passport and trap me in Moscow Airport," Snowden told NBC.
"For a supposedly smart guy, that's a pretty dumb answer, frankly," Kerry hit back.
Snowden should do the patriotic thing and return to the US to face espionage charges for leaking hundreds of thousands of classified documents, the top US diplomat said.
"This is a man who has betrayed his country," Kerry told CBS News. "He should man up and come back to the US."
"The fact is, he has damaged his country very significantly. I find it sad and disgraceful."
Snowden was granted asylum by Russia in August 2013 after spending weeks holed up in Moscow's Sheremetyevo Airport, having flown in from Hong Kong.
He says he cannot return to face trial because of the "extraordinary charges" laid against him which would bar him from using classified information in his defense.
Snowden said he had had no contact with Russian President Vladimir Putin since he was given in asylum, and denied he was being paid by the Russian government.
And he said he missed his family, colleagues and his work, insisting he was a patriot, still serving the US government.
"Sometimes to do the right thing you have to break a law," he insisted.
"Being a patriot doesn't mean prioritizing service to government above all else. Being a patriot means knowing when to protect your country, knowing when to protect your constitution," Snowden added.
"If Mr Snowden wants to come back to the United States today, we'll have him on a flight today," Kerry told NBC.
His temporary asylum expires August 1 and Snowden said "if the asylum looks like it's going to run out, then, of course, I would apply for an extension."
"I may have lost my ability to travel, but I have gained the ability to go to sleep at night, put my head on the pillow and feel comfortable that I have done the right thing even when it was the hard thing. I'm comfortable with that," Snowden concluded.

Mr Snowden is unlikely to return to the US because he knows that it being run by a bunch of unethical people who will give him the same treatment they handed out to Iraq, Libya, Syria, Afghanistan, which resulted in a few million people being no longer with us. Mr Snowden, unlike Mr Kerry and many others is very brave and a true American patriot. It is a pity the Americans do not produce a few more like him.
John Kerry is a disgrace.....every human being should strive to resist, in whatever way, the violence, both physical and governmental, of the state, of any state. And John Kerry should quit his ridiculous and pejorative discourse of masculinity and 'man-up' to the repulsive exercise of power by the state he represents. And for a supposedly smart guy, to still be talking in gendered metaphors, despite all the scholarship that has shown the problems with such discourse, is frankly quite stupid. So Mr.Kerry perhaps you ought to read-up a bit before you ask others to man-up. What a sorry and tragic world we live in ruled by either corporate or such political crocodiles.
@unbelievable: Dear Unbelievable, Why do you always get it wrong?
There is nothing preventing Snowden from returning to the USA -- except his fear of appearing in a US courtroom. USA patriots don't end up seeking asylum in Russia - end of story.
Snowden and Assange are the kind of great souls who make this world a worthwhile place. Our teachers, media, and parents must do more and a better job to teach generations to come about the United Satans of America & its western disciples.
express tribune should write more about the atrocities of the western world and our own english-medium western lowlife "Elite"
We all know who is telling the Truth, Snowdon or Susan Rice?

Bravo ! Good on you Snowden - history will remember you and Julian Asange forever being the early whistle-blowers - the world needs more of it.
