"In March 2016, we reported challenges in U.S. Citizenship and Immigration Services' (USCIS) automation of benefits processing. We conducted this follow-up audit to assess the extent to which USCIS has inappropriately issued Green Cards, evaluate its actions to recover the cards, and assess its actions and plans to prevent similar incidents in the future. We recommend USCIS improve Electronic Immigration System (ELIS) functionality and develop internal controls to avoid inappropriate Green Card issuance, standardize card recovery and tracking efforts, prevent unrecoverable card use, and enable remote identity verification and more secure card delivery methods."
