"In the debate over immigration reform, most seem to agree on this point: people who are now in the U.S. illegally should wait at the back of the line for legal residency.  That means no green card until legal immigrants get theirs.  But as NPR's Ted Robbins reports, that presents a problem because the wait for a green card can take decades." - NPR, Feb. 21, 2013.
