Scenarios for Snowden: Escape, arrest, asylum

Hong Kong (CNN) -- A narrow window of time is closing quickly for Edward Snowden, the National Security Agency contractor who has infuriated the U.S. government by leaking details of surveillance programs after fleeing the country.

As FBI agents gather evidence against him, the 29 year old is racing to find a permanent refuge while hiding out in Hong Kong on what's thought to be a 90-day tourist visa which could expire in early August.

Experts say Snowden's visa is unlikely to be extended, as he would struggle to prove that his planned stay is temporary.

"Once the 90 days are over, and unless his visa is extended, he's an illegal immigrant here and could be picked up by the police for overstaying," said Professor Simon Young, director of the Centre for Comparative and Public Law at the University of Hong Kong.

What becomes of Snowden depends on a number of factors, not least when and if the U.S. submits a "surrender request" with the Hong Kong government to pave the way for Snowden's return to the U.S.
