The Dept. of Homeland Security has finalized and issued its rule requiring employers to terminate employees who can’t be verified as legal if there is a mismatch with their name and Social Security number—or face fines ranging from $250 to $10,000 per undocumented worker. The rule describes “safe harbor” procedures that the employer can follow in response to a no match letter; DHS assures employers who follow the procedures that it will not use the letter as any part of an allegation that the employer had constructive knowledge that the worker was an alien not authorized to work in the U.S.
