U.S. Immigration Policy on Permanent Admissions, December 20, 2010

摘要

Four major principles underlie current U.S. policy on permanent immigration: the reunification of families, the admission of immigrants with needed skills, the protection of refugees, and the diversity of admissions by country of origin. These principles are embodied in the Immigration and Nationality Act (INA). The INA specifies a complex set of numerical limits and preference categories that give priorities for permanent immigration reflecting these principles. Legal permanent residents (LPRs) refer to foreign nationals who live permanently in the United States. During FY2009, a total of 1.1 million aliens became LPRs in the United States. Of this total, 66.1% entered on the basis of family ties. Other major categories in FY2009 were employmentbased LPRs (including spouses and children) at 12.7%, and refugees/asylees adjusting to LPR status at 15.7%. About 14.6 of all LPRs come from Mexico, which sent 164,920 LPRs in FY2009.
