Permanent Legal Immigration to the United States: Policy 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. The Immigration Amendments of 1965 replaced the national origins quota system (enacted after World War I) with per-country ceilings, and the statutory provisions regulating permanent immigration to the United States were last revised significantly by the Immigration Act of 1990.
The critiques of the permanent legal immigration system today are extensive, but there is no consensus on the specific direction the reforms of the law should take. As the Congress considers comprehensive immigration reform (CIR), many maintain that revision of the legal immigration system should be one of the major components of a CIR proposal. This primer on legal permanent immigration law, policies, and trends provides a backdrop for the policy options and debates that may emerge as Congress considers a revision of the legal immigration system
Permanent Employment-Based Immigration and the Per-country Ceiling
[Excerpt] The Immigration and Nationality Act (INA) specifies a complex set of categories and numerical limits for admitting lawful permanent residents (LPRs) to the United States that includes economic priorities among the admission criteria. These priorities are addressed primarily through the employment-based immigration system, which consists of five preference categories. Each preference category has specific eligibility criteria; numerical limits; and, in some cases, distinct application processes. The INA allocates 140,000 visas annually for all five employment-based LPR categories, roughly 12% of the 1.1 million LPRs admitted in FY2017. The INA further limits each immigrant-sending country to an annual maximum of 7% of all employment-based LPR admissions, known as the per-country ceiling, or “cap.”
Prospective employment-based immigrants follow two administrative processing trajectories depending on whether they apply from overseas as “new arrivals” seeking LPR status or from within the United States seeking to adjust to LPR status from a temporary status that they currently possess. While some prospective employment-based immigrants can self-petition, most require U.S. employers to petition on their behalf. In both cases, the Department of State (DOS) is responsible for allocating the correct number of employment-based immigrant “visa numbers” or slots, according to numerical limits and the per-country ceiling specified in the INA.
This report reviews the employment-based immigration process by examining six pools of pending petitions and applications, representing prospective employment-based immigrants and any accompanying family members at different stages of the LPR process. While four of these pools represent administrative processing queues, two result from the INA’s numerical limitations on employment-based immigration and the per-country ceiling

A Primer on U.S. Immigration Policy
[Excerpt] This report provides a broad overview of U.S. immigration policy. The first section addresses policies governing how foreign nationals enter the United States either to reside permanently or to stay temporarily. Related topics within this section include visa issuance and security, forms of quasi-legal status, and naturalization. The second section discusses enforcement policies both for excluding foreign nationals from admission into the United States, as well as for detaining and removing those who enter the country unlawfully or who enter lawfully but subsequently commit crimes that make them deportable. The section also covers worksite enforcement and immigration fraud. The third section addresses policies for unauthorized aliens residing in the United States. While intended to be comprehensive, this primer may omit some immigration-related topics. It does not discuss policy issues or congressional concerns about specific immigration-related policies and programs
Permanent Legal Immigration to the United States: Policy Overview
[Excerpt] 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 asylees, and the diversity of immigrants by country of origin. These principles are embodied in the Immigration and Nationality Act (INA) and are reflected in different components of permanent immigration. Family reunification occurs primarily through family sponsored immigration. U.S. labor market contribution occurs through employment based immigration. Humanitarian assistance occurs primarily through the U.S. refugee and asylee programs. Origin country diversity is addressed through the Diversity Immigrant Visa
Rural Hispanics At A Glance
Rural Hispanics at a Glance provides the latest information from the 2000 Census and other Federal data sources about Hispanics living in nonmetro counties. This six-page brochure highlights growth and geographic dispersion, demographic characteristics, and the most recent indicators of social and economic conditions for this population. It emphasizes rapid Hispanic population growth, particularly in new rural destinations of the Midwest and Southeast, and it illustrates differences in age structure between Hispanics and non-Hispanic Whites. The report also provides data on important demographic, labor market, income, poverty, and social service indicators for nonmetro Hispanics. Using a visually interesting format that incorporates text bullets with charts and maps, it quickly provides information on key indicators of the rural Hispanic population to assist public officials, community organizations, private decision makers and others in their efforts to enhance the economic opportunities and quality of life for this rapidly growing population.Farm Structure, Employment and Wages, Agribusiness, Food processing, Rural Policy Food and Nutrition, Poverty and Economy, Rural America, Rural Income, Rural Welfare, Labor and Education, Rural Population, and Rural Migration, ERS, USDA, Agribusiness, Agricultural and Food Policy, Food Consumption/Nutrition/Food Safety,
Child Welfare and Alaska Native Tribal Governance: A Pilot Project in Kake, Alaska — Report of Findings
This report details research on child welfare decision-making in Kake in the context of a proposed ordinance for the establishment of an organized tribal court in the village. The tribal court did not, in fact, come into being at that time, but the researchers were able to follow the development of a different local decision-making approach — circle sentencing. The research revealed that welfare issues and problems were handled through a variety of informal and formal methods that reflected Tlingit cultural emphases. Ideas arising from outside, such as circle sentencing, were selectively adapted.National Science FoundationOverview / Responding to Children's Cases / Choice of Foru
