Summary: The Immigration and Naturalization Service (INS) invests hundreds of millions of dollars each year in information technology (IT) to help (1) prevent aliens from entering the United States illegally and remove aliens who succeed in doing so and (2) provide services or benefits to facilitate entry, residence, employment, and naturalization to legal immigrants. The Clinger-Cohen Act requires agency heads to implement a process for maximizing the value and assessing and managing the risks of its IT investments. GAO examined leading private and public sector IT management practices to determine whether INS is effectively managing its IT investments and whether the Department of Justice (DOJ) is effectively promoting, guiding, and overseeing INS' investment management activities. GAO found that INS lacks the basic capabilities upon which to build IT investment management maturity. Furthermore, INS is not managing IT investments as a complete portfolio. By managing its IT investments as individual projects, INS will not be able to determine which investments contribute most to the agency mission. GAO also found that DOJ is not guiding and overseeing INS' investment management approach.
