Edward Snowden, the former National Security Agency (NSA) IT contractor now living in Russia following his high-profile data leak, won't return to the United States until current laws are changed. The federal Whistleblower Protection Act isn't applicable to former government contractors, which means he could face significant legal trouble if he returns to the United States.
"Returning to the U.S., I think, is the best resolution for the government, the public, and myself, but it's unfortunately not possible in the face of current whistleblower protection laws," Snowden said in response to a question about getting a fair shake if he one day returns to the United States.
It seems highly unlikely Snowden will return to the U.S. unless he's offered immunity by the U.S. government, which is something the White House hasn't recently discussed publicly. It seems that the NSA and other government agencies would be able to learn from Snowden, but he won't touch U.S. soil just to face possible espionage charges.
Snowden is currently in Russia where he was given one-year asylum, and could eventually find his way to a country like Brazil after his stay in Russia ends. There are rumors private Russian companies are interested in hiring Snowden and trying to help him secure permanent residency.
