OVERLAND PARK The U.S. Citizenship and Immigration Service plans to add 500 workers in Overland Park.

The agency said this week the new workers will help with extra paperwork caused by a presidential order this summer that allows young undocumented workers to stay in the U.S. without fear of deportation.

The employees will work for the CIS national benefits center, with operations expected to begin in mid-December.

The presidential directive applied to illegal immigrants not over the age of 30 who came to the U.S. when they were younger than 16. They have to live in the country for at least five years and have no felony or significant misdemeanor convictions.
