A young, ambitious immigrant from Guatemala who dreamed of becoming an architect. A Nigerian medic. A soldier from China who boasted he would one day become an American general. An Indian native whose headstone displays the first Khanda, emblem of the Sikh faith, to appear in Arlington National Cemetery.

These were among more than 100 foreign-born members of the U.S. military who earned American citizenship by dying in Iraq.
There are tens of thousands of foreign-born members in the U.S. armed forces. Many have been naturalized, but more than 20,000 are not U.S. citizens.

"Green card soldiers," they are often called, and early in the war, Bush signed an executive order making them eligible to apply for citizenship as soon as they enlist. Previously, legal residents in the military had to wait three years.

Since Bush's order, nearly 37,000 soldiers have been naturalized. And 109 who lost their lives have been granted posthumous citizenship.

They are buried with purple hearts and other decorations, and their names are engraved on tombstones in Arlington as well as in Mexico and India and Guatemala.
Others question whether non-citizens should even be permitted to serve. Mark Krikorian of the conservative Center for Immigration Studies, argues that defending America should be the job of Americans, not non-citizens whose loyalty might be suspect. In granting special benefits, including fast-track citizenship, Krikorian says, there is a danger that soldiering will eventually become yet another job that Americans won't do.

And yet, immigrants have always fought — and died — in America's wars.
