A soldier becomes a citizen. Army Staff Sgt. Hilbert Caesar, an immigrant from Guyana, lost a leg in Iraq, serving the U.S. "Caesar, 26, is one of thousands of immigrants in the military to become citizens since President Bush issued an order in July 2002 expediting their naturalization. About 32,400 noncitizens are serving in the armed forces, or roughly 2.3 percent of the total." After the ceremony he yelled "Hoo-ah!" And then said: "I knew I was an American before this. I always knew I was an American."
