Number: RS22111 Title: Alien Legalization and Adjustment of Status: A Primer Authors: Ruth Ellen Wasem, Domestic Social Policy Division Abstract: Immigration patterns have changed substantially since 1952, when policy makers codifying the Immigration and Nationality Act assumed that most aliens becoming legal permanent residents (LPRs) of the United States would be arriving from abroad. In 1975, more than 80% of all LPRs arrived from abroad. By 2005, however, only 34% of all aliens who became LPRs had arrived from abroad; most LPRs adjust status within the United States. This report summarizes the main avenues for foreign nationals currently in the United States - legally or illegally - to become LPRs. Alien legalization or "amnesty," as well as adjustment of status and cancellation of removal options, are briefly discussed. Designed as a primer on the issues, the report provides references to other CRS products that track pertinent legislation and analyze these issues more fully. Pages: 6 Date: January 23, 2007
