In the war on terror, the government is rounding up foreigners, checking their immigration status, and then, sometimes, deporting them. It won't give out their names.

Hyder's story continues. He and his convoy of American soldiers run into trouble on their way back home.

It's possible that the very first teenager to heed his invitation was Hyder Akbar, 17, from Concord, California. In the summer of 2002, he travelled with his father to live in their home country.

Hyder notices changes in Kabul in the year since he visited Afghanistan. Then he heads to Kunar, near the Pakistan border, one of the remote regions where Al Qaeda, the Taliban and local warlords are still fighting the new Afghan government and the U.S. military.

In January 2002-- not long after the Taliban were driven from power in Afghanistan-- he came to the United States, partly to be on hand for the State of the Union address last year. And while he was here, he spoke with an audience that was mostly Afghan-Americans at Georgetown University.

When Hyder was 17, he went to Afghanistan. This place that he'd been hearing about his whole life.
