SWORN ON THE FOURTH OF JULY -- U.S. President Barack Obama greets Marine lance corporal Byron Acevedos, formerly a Guatemalan citizen who earned a Purple Heart before he earned his U.S. citizenship, as U.S. Citizenship and Immigration Services Director Alejandro Mayorkas and Secretary of Homeland Security Janet Napolitano watch during a naturalization ceremony for active duty service members in the East Room of the White House in Washington July 4, 2012.

Four Filipinos, two Salvadoran women and a Palauan born in the tiny island republic in the middle of the Pacific Ocean were among the 25 young men and women who chose to serve a country that had not yet recognized them as citizens. On the Fourth of July, they finally obtained that recognition, by taking their oaths in the presence of their commander in chief, President Barack Obama. Since 2001, the U.S. has been fast-tracking foreign-born residents for citizenship if they volunteer for any branch of military service.
