Household workers are the unseen face of immigration issues
"In the debate over immigration, they are virtually unheard, unseen: the hundreds of thousands of foreign-born women, many of them in the U.S. illegally, who toil as nannies, cooks and housekeepers, changing diapers and scrubbing floors.
They are jobs of last resort for people whose other options are few."
