Immigration activists march in downtown Los Angeles on August 25, 2007 to protest the deportation of illegal immigrant Elvira Arellano whose U.S.-born son stayed behind. Arellano, a native of the Mexican state of Michoacan, became a lighting rod for the debate over illegal immigration when she holed up in a Chicago church seeking sanctuary from federal agents who were trying to kick her out of the country. Arellano opted to leave her 8-year-old son Saul - a U.S. citizen by birth - in the Chicago area where he is expected to attend public school in the fall. Elvira Arellano and Saul are pictured in photo poster at left. (UPI Photo/Jim Ruymen)
