How long should foreigners’ temporary refuge last?

In 2001, after massive earthquakes killed more than 1,000 people and displaced more than 1 million in El Salvador, the United States made room for people who had come here illegally fleeing the catastrophe. It was an act of generosity taken by President George W. Bush under a federal program known as temporary protected status. Some 200,000 people took advantage of the offer to live and work legally in this country.
