Lawsuit: Man deported after being part of protection program

A man has been sent to Mexico in what an advocacy group says could be the first known deportation of someone who was part of a program to shield people who came to the U.S. as young children.

The National Immigration Law Center sued the federal government Tuesday in San Diego to obtain records on Juan Manuel Montes, who was detained by the Border Patrol in February in the California border town of Calexico.

The advocacy group says the 23-year-old Montes had permission to work and live in the United States in the program that was introduced in 2012 to shield people from being deported.

U.S. Customs and Border Protection said it doesn't comment on pending litigation.

U.S. Citizenship and Immigration Services didn't immediately respond to a request for comment.
