Question About Immigration Law:

The NY Times today profiles a 21 year old "American" jihadist blogger, Samir Khan, born in Saudi Arabia, raised in Queens, living in North Carorlina. I put "American" in quotes because it's not clear whether Khan is an American citizen.

Khan serves as an intermediary to the jihadists of the world, posting their videos and statements on his blog. Here is a example of Khan's perspective:

He described his favorite video from Iraq: a fiery suicide-bomber attack on an American outpost.

"It was something that brought great happiness to me," he said. "Because this is something America would never want to admit, that they are being crushed."

Asked how he felt living among people who had sent soldiers to Iraq, Mr. Khan said: "Whatever happens to their sons and daughters is none of my concern. They are people of hellfire and I have no concern for them."

I'm curious: assuming that (1) Khan is not a citizen; and (2) he has not violated any criminal laws, does American immigration law, tempered by constitutional considerations, provide grounds for deporting him? I'm less interested in knowing whether readers think Khan should be deported, which will lead to an utterly predictable set of comments, and more curious about whether there is any law addressing the subject, and what it says.
