WASHINGTON -- The United States spends more money on immigration enforcement -- nearly $18 billion in the 2012 fiscal year -- than on its other law enforcement agencies combined, according to a report released Monday from the nonpartisan Migration Policy Institute.

That spending went to U.S. Immigration and Customs Enforcement, Customs and Border Protection and US-Visit, a program that helps states and localities identify undocumented immigrants.

By contrast, the U.S. spent $14.4 billion -- combined -- on its other prime law enforcement agencies: the FBI, Secret Service, Drug Enforcement Administration, U.S. Marshal Service and Bureau of Alcohol, Tobacco, Firearms and Explosives.

There's a reason for the high cost. The Migration Policy Institute found that ICE and CBP also refer more cases to prosecution than those other agencies combined, and the immigration agencies also held more individuals in fiscal year 2011 than the federal Bureau of Prisons.

Still, the numbers are striking. Immigration enforcement has expanded rapidly since 1986, when Congress passed the enforcement-heavy Immigration Reform and Control Act. Since then, the U.S. has spent nearly $187 billion on immigration enforcement, according to the report. The Sept. 11 terrorist attacks in 2001, which led to the creation of the Department of Homeland Security that now houses immigration enforcement, made the spending surge even more marked.

The government spends about 15 times more on immigration enforcement than it did in the mid-1980s, adjusted for inflation, the report found.

At the same time, deportations have exploded. The U.S. deported about 30,000 people in the 1990 fiscal year; in the 2012 fiscal year, it removed a record 409,894. A majority of those people were deported without an order from an immigration judge, instead using DHS' discretion, the Migration Policy Institute found.

Immigration enforcement is more in focus than ever this year, as Congress and the White House begin work on a bipartisan agreement for reform of the system. The Obama administration, while deporting a record number of people, has put in place some reforms to focus more on high-priority immigrants, such as convicted criminals. It also implemented the deferred action program to stop deporting some undocumented young people. Those policies were met by some on the right with the claim that the administration doesn't care to enforce immigration law, a possible sticking point as the two sides seek to find an agreement.

The Migration Policy Institute found that border enforcement is, for the most part, working. Doris Meissner, director of immigration policy at the institute and a former commissioner of the U.S. Immigration and Naturalization Service, told reporters on a conference call that she is somewhat baffled by the insistence that the U.S.-Mexico border is out of control, sometimes brought forth by people who want to block reform.

"I really don't know," Meissner said when asked why so many people say border enforcement is failing. "I do think a lot of it is just old, the standard imagery of people coming across the border, of the revolving door, of border patrol feeling besieged. Things just haven't caught up -- it's a disconnect."

  • The Naturalization Act of 1790

    The Naturalization Act of 1790 was our country's first set of laws dealing with citizenship. Applicants had to be "<a href="http://rs6.loc.gov/cgi-bin/ampage?collId=llsl&fileName=001/llsl001.db&recNum=226 " target="_hplink">a free white person</a>" of "good moral character." This excluded indentured servants and slaves. Good moral character was substantiated by establishing residence for at least one year in the state from where he was applying, and at least two years of residence in the country. The Naturalization Act of 1795 would extend that requirement to five years, and is still standard today.

  • The Fourteenth Amendment, 1868

    A Reconstruction Amendment that was added to the U.S. Constitution following the Civil War, the Citizenship Clause of the 14th Amendment establishes for the first time that children born on U.S. soil would be conferred U.S. citizenship regardless of their parent's citizenship status, race, or place of birth. Last year, Rep. Steve King (R-IA) introduced the <a href="http://www.govtrack.us/congress/bills/112/hr140 " target="_hplink">Birthright Citizenship Act of 2011</a> to Congress, and challenged this. The bill would require that at least one parent be a U.S. citizen or permanent resident for a child to be granted citizenship. According to the <a href="http://www.opencongress.org/bill/112-h140/text " target="_hplink">bill's text</a>, the Birthright Citizenship Act of 2011 would amend the Immigration and Nationality Act of 1952, and "clarify those classes of individuals born in the United States who are nationals and citizens of the United States at birth." Prior to this, Rep. Nathan Deal (R-GA) <a href="http://www.huffingtonpost.com/2009/05/26/nathan-deal-georgia-lawma_n_207485.html " target="_hplink">introduced</a> a similar <a href="http://www.opencongress.org/bill/111-h1868/show" target="_hplink">bill</a> in 2009.

  • The Naturalization Act of 1870

    The Naturalization Act of 1870<a href="http://thepoliticsofimmigration.org/pages/chronology.htm " target="_hplink"> explicitly extended</a> naturalization laws to "aliens of African nativity and persons of African descent." This meant that for the first time, African-American children would be conferred citizenship upon birth. Asian immigrants and other people of color are excluded per the Naturalization Acts of 1790 and 1795.

  • The Page Act of 1875

    Named after Republican Representative Horace F. Page, this is the first U.S. federal immigration law to explicitly prohibit the immigration of a particular group: persons of Asian descent. Primarily meant to limit Chinese immigrant labor and prostitution, the Page Act prohibited the immigration of: (1) contracted labor from "China, Japan, or any Oriental country" that was not "free and voluntary," (2) Chinese prostitution and (3) criminals and women who would engage in prostitution. Ultimately, the <a href="http://www.uchastings.edu/racism-race/pageact.html " target="_hplink">Page Act</a> severely <a href="http://immigration-online.org/228-page-act-united-states-1875.html " target="_hplink">restricted</a> the immigration of Asian women. Only 136 of the the nearly 40,000 Chinese immigrants who arrived in the months before the bill's enforcement were women. And, it would pave the way for the Chinese Exclusion Act. In this picture, Michael Lin, chair of the 1882 Project, a coalition of rights groups seeking a statement of regret over that year's Chinese Exclusion Act, speaks on May 26, 2011 in Washington, DC, at the US House of Representatives in front of a reproduction of a 19th-century sign that aimed at rousing up sentiment against Chinese Americans. Lawmakers introduced a bill that would offer an official statement of regret for the act, which banned further immigration of Chinese to the United States and ended citizenship rights for ethnic Chinese.

  • The Chinese Exclusion Act, 1882

    Signed by President Chester A. Arthur, the <a href="http://www.pbs.org/weta/thewest/resources/archives/seven/chinxact.htm " target="_hplink">Chinese Exclusion Act</a> was the first federal immigration law to prohibit immigration on the basis of race. The bill barred all Chinese laborers, skilled and unskilled, from immigrating to the U.S. for ten years. It was made permanent by 1903, and was not lifted until the 1943 Magnuson Act. The 1898 Supreme Court <a href="http://ocp.hul.harvard.edu/immigration/exclusion.html " target="_hplink">decision</a> in <em>United States v. Wong Kim Ark</em> finally extended naturalization laws to persons of Chinese descent by ruling that anyone born in the United States was indeed a U.S. citizen. This editorial cartoon from 1882 shows a Chinese man being excluded from entry to the "Golden Gate of Liberty." The sign next to the iron door reads, "Notice--Communist, Nihilist, Socialist, Fenian & Hoodlum welcome. But no admittance to Chinamen." At the bottom, the caption reads, "THE ONLY ONE BARRED OUT. Enlightened American Statesman--'We must draw the line <em>somewhere</em>, you know.'" (Image Source: Frank Leslie's illustrated newspaper, vol. 54 (1882 April 1), p. 96.

  • The Immigration Act of 1924

    U.S. President Coolidge signed this U.S. federal <a href="http://history.state.gov/milestones/1921-1936/ImmigrationAct " target="_hplink">bill</a> into law. It capped the number of immigrants who could be admitted entry to the U.S. and barred immigration of persons who were not eligible for naturalization. And, as the Naturalization Act of 1790 required, an immigrant had to be white in order to naturalize. The quotas varied by country.
