	Overview

Four major principles currently underlie U.S. policy on legal 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 federal law, the Immigration and Nationality Act (INA) first codified in 1952. As defined in the INA, immigrants are synonymous with legal permanent residents (LPRs) and refer to foreign nationals who come to live lawfully and permanently in the United States. Immigrant admissions and adjustments to LPR status are subject to a complex set of numerical limits and preference categories that give priority for admission on the basis of family relationships, needed skills, and geographic diversity, as discussed below. FY2010 Admissions

During FY2010, a total of 1,042,625 foreign nationals became LPRs in the United States. Of the total LPRs in FY2010, 66.3% entered on the basis of family ties. Immediate relatives of U.S. citizens made up the single largest group of immigrants—476,414 as Figure 5 indicates. Additional major immigrant groups in FY2010 were employment-based preference immigrants (including spouses and children), who comprised 14.2%, and refugees and asylees adjusting to LPR status, who comprised 13.1%. Substantial efforts to reform legal immigration have failed in the recent past, prompting some to characterize the issue as a "zero-sum game" or a "third rail." The challenge inherent in reforming legal immigration is balancing employers' hopes to increase the supply of legally present foreign workers, families' longing to re-unite and live together, and a widely shared wish among the various stakeholders to improve the policies governing legal immigration into the country. Whether the Congress will act to alter immigration policies—either in the form of comprehensive immigration reform or in the form of incremental revisions aimed at strategic changes—is at the crux of the debate. Addressing these contentious policy reforms against the backdrop of economic crisis sharpens the social and business cleavages and may narrow the range of options. Family-Based Preferences

Proponents of family-based migration point to the significant backlogs in family based immigration due to the sheer volume of aliens eligible to immigrate to the United States and maintain that any proposal to reform immigration levels should also include the option of family-based backlog reduction. Citizens and LPRs often wait years for their relatives' petitions to be processed and visa numbers to become available. Some proponents of immigration reform argue that the immediate relatives of LPRs should be treated as immediate relatives of U.S. citizens are treated under the INA. Other options would scale back family-based immigration levels, including the option of limiting family-based LPRs to the immediate relatives of U.S. citizens. Even as U.S. unemployment levels remain high, employers assert that they continue to need the "best and the brightest" workers, regardless of their country of birth, to remain competitive in a worldwide market and to keep their firms in the United States. While support for the option of increasing employment based immigration may be dampened by the economic recession, proponents argue it is an essential ingredient for economic growth.

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 FY2010, a total of 1.0 million aliens became LPRs in the United States. Of this total, 66.3% entered on the basis of family ties. Immediate relatives of U.S. citizens made up the single largest group of immigrants—476,414—in FY2010. Other major categories in FY2010 were employment-based LPRs (including spouses and children) and refugees/asylees adjusting to LPR status—14.2% and 13.1%, respectively. About 13.3% all LPRs come from Mexico, which sent 139,120 LPRs in FY2010.

Even as U.S. unemployment levels remain high, employers assert that they continue to need the "best and the brightest" workers, regardless of their country of birth, to remain competitive in a worldwide market and to keep their firms in the United States. While support for the option of increasing employment-based immigration may be dampened by the level of unemployment, proponents argue it is an essential ingredient for economic growth. Other possible options are to admit LPRs on the basis of a point system comprised of education and needed skills or to establish a independent agency or commission that would set the levels and types of employment-based immigrants.
Proponents of family-based migration alternatively point to the significant backlogs in family based immigration due to the sheer volume of aliens eligible to immigrate to the United States and maintain that any proposal to increase immigration levels should also include the option of family-based backlog reduction. Citizens and LPRs often wait years for their relatives' petitions to be processed and visa numbers to become available. Possible options include treating the immediate relatives of LPRs as immediate relatives of U.S. citizens are treated under the INA, (i.e., not held to numerical limits or per-country ceilings).
Against these competing priorities for increased immigration are those who offer options to scale back immigration levels, with options ranging from limiting family-based LPRs to the immediate relatives of U.S. citizens to confining employment-based LPRs exceptional, extraordinary, or outstanding individuals.
