Numerical Limits on Employment-Based Immigration: Analysis of the Per-Country Ceilings

Ruth Ellen Wasem
Specialist in Immigration Policy

The Immigration and Nationality Act (INA) specifies a complex set of numerical limits and preference categories that include economic priorities among the criteria for admission. The INA allocates 140,000 visas annually for employment-based legal permanent residents (LPRs), and they were 14.2% of the total 1.0 million LPRs in FY2010. The INA further specifies that each year, countries are held to a numerical limit of 7% of the worldwide level of U.S. immigrant admissions, known as per-country limits or country caps.

Even as U.S. unemployment levels remain high, some 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 economic conditions, proponents argue it is an essential ingredient for economic growth. Those opposing increases in employment-based LPRs assert that there is no compelling evidence of labor shortages and cite the rate of unemployment across various occupations and labor markets.

With this economic and political backdrop, the option of lifting the per-country caps on employment-based LPRs has become increasingly popular. Some theorize that the elimination of the per-country caps would increase the flow of high-skilled immigrants without increasing the total annual admission of employment-based LPRs. The presumption is that many high-skilled people (proponents cite those from India and China, in particular) would then move closer to the head of the line to become LPRs.

To explore this policy option, analyses of approved pending employment-based petitions are performed on two different sets of data: approved pending cases with the Department of State National Visa Center, and approved pending cases with U.S. Citizenship and Immigrant Services (USCIS). The overwhelming number of approved employment-based LPR visas pending at the National Visa Center at the close of FY2010 were those of professional and skilled workers— 102,395. There were also 16,788 approved visas pending for unskilled workers. In terms of those with advanced degrees, another 6,738 visas were pending. There were also 2,961 approved visas pending in the “extraordinary” category. In terms of the USCIS data, most of the approved I-485 petitions pending are professional, skilled, and unskilled workers (114,442). There were 7,545 approved I-485 petitions pending in the “extraordinary” category and 45,573 approved I-485 petitions pending in the “advanced degree” category. The extent that these two sets of data overlap—and thus may be counting the same petitions twice—is not known, but substantial duplication is presumed to exist.

The top four countries in both the National Visa Center and USCIS data sets are (in rank order) India, the Philippines, the Peoples’ Republic of China, and Mexico. The data analyses suggest that the vast number of Indians are waiting to adjust status in the United States, while the vast number of Filipinos are waiting to immigrate from abroad. Those with approved pending cases from China seem to be more evenly split among new arrivals and those seeking to adjust status.

Some argue that the per-country ceilings are arbitrary and observe that employability has nothing to do with country of birth. Others maintain that the statutory per-country ceilings restrain the dominance of high-demand countries and preserve the diversity of the immigrant flows. Legislation to revise the per-country ceilings on LPRs passed the House (H.R. 3012) on November 29, 2011.

Interior Immigration Enforcement: Programs Targeting Criminal Aliens

Marc R. Rosenblum

Analyst in Immigration Policy

Congress has a long-standing interest in seeing that immigration enforcement agencies identify and deport serious criminal aliens. The expeditious removal of such aliens has been a statutory priority since 1986, and the Department of Homeland Security (DHS) and its predecessor agency have operated programs targeting criminal aliens for removal since 1988. These programs have grown substantially since FY2005.

Despite the interest in criminal aliens, inconsistencies in data quality, data collection, and definitions make it impossible to precisely enumerate the criminal alien population, defined in this report as all noncitizens ever convicted of a crime. CRS estimates the number of noncitizens incarcerated in federal and state prisons and local jails—a subset of all criminal aliens—at 173,000 in 2009, with state prisons and local jails accounting for somewhat more incarcerations than federal prisons. The overall proportion of noncitizens in federal and state prisons and local jails corresponds closely to the proportion of noncitizens in the total U.S. population.

DHS operates four programs designed in whole or in part to target criminal aliens: the Criminal Alien Program (CAP), Secure Communities, the § 287(g) program, and the National Fugitive Operations Program (NFOP). The CAP, Secure Communities, and certain § 287(g) programs are jail enforcement programs that screen individuals for immigration-related violations as they are being booked into jail and while they are incarcerated; the NFOP and some other § 287(g) programs are task force programs that target at-large criminal aliens. This report describes how these programs work and identifies their common features and key differences among them.

While consensus exists on the overarching goal to identify and remove serious criminal aliens, these programs have generated controversy, particularly Secure Communities and the § 287(g) program. On one hand, the Obama Administration and other supporters of jail enforcement programs see them as efficient and even-handed ways to identify criminal aliens. The Administration has taken steps to strengthen and expand Secure Communities and plans to implement the program in every law enforcement jurisdiction in the country by 2013. On the other hand, some lawmakers and advocacy groups have raised concerns that Secure Communities and the § 287(g) program have not been narrowly targeted at serious criminal offenders and that the programs may have adverse impacts on police-community relations, may result in racial profiling, and may result in the detention of people who have not been convicted of criminal offenses and may not be subject to removal.

Disagreements about the merits of jail enforcement programs overlap with a separate set of questions about the role of states and localities in immigration enforcement. These jurisdictional questions have focused in particular on Secure Communities, in part because the Administration initially appeared to present it as a discretionary program but now takes the position that states and localities may not “opt out” of Secure Communities.

Fiscal Impacts of the Foreign-Born Population

William A. Kandel
Analyst in Immigration Policy

This report reviews estimates of fiscal impacts to the federal, state, and local governments of the foreign born who reside in the United States. It examines the academic and policy literature on fiscal impacts of two populations: all U.S. foreign born and unauthorized aliens. Computing such fiscal impacts involves numerous methodological and conceptual challenges, and resulting estimates vary considerably according to the assumptions used, including those about the time frame considered, the treatment of U.S.-born children, the unit of analysis used, and which costs and revenues are included.

For the total foreign-born population, the findings of a 1996 analysis commissioned by the National Research Council entitled The New Americans remain authoritative and relevant. The report estimated that each new immigrant at that time, with his or her descendents, would generate an average net fiscal surplus. The authors illustrated how their estimate varied according to foreign-born residents’ age composition and educational attainment. Varied assumptions about education generated substantially different impacts. For instance, immigrants with above-average education generated a considerably larger than average net fiscal surplus; those with belowaverage education levels generated a net fiscal deficit. Reducing the time frame of the analysis to fewer generations changes the average net fiscal surplus into an average net fiscal deficit.

This study and others confirm that the foreign born, like the native born, impose their largest costs on U.S. taxpayers as children, through their consumption of public education, and as the elderly, through their consumption of government-funded public health programs. Yet, the majority of the foreign born come to the United State as young adults, where they pay taxes and contribute to programs like Social Security for most of their working lives. Relatively young ages at arrival for most foreign born helps explain why many fiscal impact studies found that foreignborn residents generated net fiscal surpluses over the long term.

Findings from all of the studies reviewed in this report indicate different impacts at the state and federal levels. Many federal programs such as Social Security and Medicaid are oriented toward assisting the elderly, while many state and local level jurisdictions are responsible for services consumed by younger persons, such as public education and criminal justice administration. Foreign-born residents’ relatively young age distribution thus accentuates the degree to which states and localities incur greater fiscal costs from the foreign born than the federal government. Fiscal impact studies of unauthorized aliens reach less consensus than those of the total foreignborn population. Three national estimates evaluated in a 1995 General Accounting Office (GAO) report varied considerably and left the agency unable to definitively quantify such fiscal impacts. Subsequent state-level studies emphasized fiscal impacts of costly public services: public education, health care, and law enforcement. Many estimated tax and other fiscal contributions.

Studies estimating fiscal impacts for unauthorized aliens are more likely to yield estimated net fiscal deficits than those estimating fiscal impacts for all foreign born, because unauthorized aliens, on average, tend to be younger and less educated. Consequently, they are more likely to use public education for their children and contribute relatively less in tax revenues compared to all foreign born. Given their unauthorized status, they are also less likely themselves to receive public benefits, although their U.S. born children may be more likely to qualify for such benefits. However, deriving more specific conclusions or estimates from studies of unauthorized aliens reviewed in this report remains elusive due to variation in study design and methodology.

Despite President Obama’s calls for a national conversation on immigration reform, immigration has not been a front-burner issue for the 112th Congress. The 112th Congress, however, has taken legislative action on some measures containing provisions on a range of immigration-related topics. The Department of Defense and Full-Year Continuing Appropriations Act, 2011 (P.L. 112- 10) includes a provision terminating a special refugee provision known as the Lautenberg amendment. The Department of Homeland Security (DHS) Appropriations Act, 2012 (H.R. 2017), as passed by the House and reported by the Senate Appropriations Committee, contains border security-related provisions on staffing at ports of entry and enforcement activities between ports of entry. The House has passed legislation to reauthorize the H-1C temporary worker category for nurses coming to work in medically underserved areas in the United States (H.R. 1933). It also has passed legislation concerning military service-based immigration benefits (H.R. 398).

In other legislative action, the House Judiciary Committee has reported or ordered reported bills on electronic employment eligibility verification (H.R. 2885), immigrant detention (H.R. 1932), visa security (H.R. 1741), and the diversity visa (H.R. 704). House and Senate committees and subcommittees have held hearings on these and other immigration-related issues.

This report discusses these and other immigration-related issues that have received legislative action or are of significant congressional interest in the 112th Congress. DHS appropriations are addressed in CRS Report R41982, Homeland Security Department: FY2012 Appropriations, and, for the most part, are not covered here.

Unauthorized Aliens Residing in the United States: Estimates Since 1986

Ruth Ellen Wasem
Specialist in Immigration Policy

Estimates derived from the March Supplement of the U.S. Census Bureau’s Current Population Survey (CPS) indicate that the unauthorized resident alien population (commonly referred to as illegal aliens) rose from 3.2 million in 1986 to 11.2 million in 2010. Jeffrey Passel, a demographer with the Pew Hispanic Research Center, has been involved in making these estimations since he worked at the U.S. Bureau of the Census in the 1980s. The estimated number of unauthorized aliens had dropped to 1.9 million in 1988 following passage of a 1986 law that legalized several million unauthorized aliens. The estimates of unauthorized aliens peaked at an estimated 12.4 million in 2007. About 39% of unauthorized alien residents in 2010 were estimated to have entered the United States in 2000 or later.

Similarly, the Department of Homeland Security’s Office of Immigration Statistics (OIS) reported an estimated 10.8 million unauthorized alien residents as of January 2010, up from 8.5 million in January 2000. The OIS estimated that 6.6 million of the unauthorized alien residents were from Mexico, an estimate comparable to Passel and D’Vera Cohn’s calculation of 6.5 million. The OIS based its estimates on data from the U.S. Census Bureau’s American Community Survey. The OIS estimated that the unauthorized resident alien population in the United States increased by 37% over the period 2000 to 2008, then leveled off in 2009 and 2010.

Research suggests that various factors have contributed to the ebb and flow of unauthorized resident aliens, and that the increase is often attributed to the “push-pull” of prosperity-fueled job opportunities in the United States in contrast to limited or nonexistent job opportunities in the sending countries. Accordingly, the economic recession that began in December 2007 may have curbed the migration of unauthorized aliens, particularly because sectors that traditionally rely on unauthorized aliens, such as construction, services, and hospitality, have been especially hard hit.

Some researchers also suggest that the increased size of the unauthorized resident population during the late 1990s and early 2000s is an inadvertent consequence of border enforcement and immigration control policies. They posit that strengthened border security has curbed the fluid movement of seasonal workers. This interpretation, generally referred to as a caging effect, argues that these policies have raised the stakes in crossing the border illegally and created an incentive for those who succeed in entering the United States to stay.

The current system of legal immigration is cited as another factor contributing to unauthorized alien residents. The statutory ceilings that limit the type and number of immigrant visas issued each year create long waits for visas. According to this interpretation, many foreign nationals who would prefer to come to the United States legally resort to illegal avenues in frustration over the delays. It is difficult, however, to demonstrate a causal link or to guarantee that increased levels of legal migration would absorb the current flow of unauthorized migrants. Furthermore, some researchers speculate that the doubling in deportations since 2001 might also have had a chilling effect on family members weighing unauthorized residence in recent years.

Some observers point to more elusive factors when assessing the ebb and flow of unauthorized resident aliens—such as shifts in immigration enforcement priorities away from illegal entry to removing suspected terrorists and criminal aliens, or discussions of possible “amnesty” legislation. This report does not track legislation and will be updated as needed.
