Lots of non-US citizens have been charged and found guilty of espionage by the US. The cold war is full of examples: http://en.wikipedia.org/wiki/History_of_Soviet_and_Russian_e...

I'm not sure whether you have to be physically present in the US to be guilty of espionage. The game has changed somewhat. It used to be that you had send someone to sneak inside buildings in the middle of the night, taking photos of secret documents on James bond mini-cameras hidden in fake fountain pens.

These days, you just hack the computer network remotely, or write a computer worm that monitors the 'good stuff' and sends it home to 'mama' in Fort Meade.

I am not sure you have to be found guilty of anything by anyone. The game has changed somewhat. All it takes is for someone to decide that you deserve a spot on president's kill list [1] and one predator strike later you are no more.

Luckily for Assange it wouldn't go down so well for UK-US relations if the president ordered a predator strike on Ellingham Hall: http://en.wikipedia.org/wiki/Ellingham_Hall,_Norfolk#Refuge
