Steve King’s Tall Tales About Immigrants and Crime Don’t Add Up
There is no denying that Rep. Steve King (R-IA) has a vivid imagination. As he sits in Border Patrol vehicles at night, he apparently sees hundreds of DREAM Act-eligible drug mules with muscular calves hauling heavy loads of marijuana across the border. How does he know these drug mules would meet the rather stringent criteria for legalization under the DREAM Act? Hard to say. How does he know these drug mules outnumber their valedictorian counterparts by a ratio of one hundred to one? No one can say. What is certain is this: when it comes to the topic of immigration and crime, nativists like King have no need for facts when there is so much fear and innuendo at their disposal. Perhaps this is because the facts are so stacked against them. Read More
Immigration Reform an Imperative for Cities and Metropolitan Areas
Metropolitan leaders from around the country made the case for immigration reform at an event hosted by the Brookings Institution’s Metropolitan Policy Program today. Over 80 percent of the U.S. population, including 95 percent of immigrants, now live in metropolitan areas; cities and towns across the country therefore have a huge stake in passing immigration reform. In fact, panelists agreed that comprehensive immigration reform is an imperative for metropolitan areas. “We need an immigration system that is keeping with the times,” stated Audrey Singer, a Senior Fellow with Brookings.

Former Attorney General Gets it Wrong on DOMA and Same Sex Immigration Benefits
Former Attorney General Alberto R. Gonzales is advocating in the New York Times that the Supreme Court decision in U.S. v. Windsor, which invalidated Section 3 of the Defense of Marriage Act (DOMA), should not allow the Obama administration to afford immigration benefits to married, same-sex bi-national couples. Rather, he argues, the administration is bound by a disturbing, 30-year-old Ninth Circuit case, Adams v. Howerton, which rested on discriminatory and outdated law and facts. Essentially, Mr. Gonzales is urging that the administration ignore 30 years of social progress and legal developments and return to a 20th century mentality and jurisprudence. He is mistaken.

Supreme Court’s DOMA Decision Good for Economic Competitiveness
In the global economy of the twenty-first century, a globally mobile workforce is critical to remaining competitive. Yet for LGBT employees, their families, and their employers, significant barriers remain in place. The Supreme Court’s June 26 decision in United States v. Windsor finding part of the Defense of Marriage Act (DOMA) unconstitutional has clear and direct benefits for married same-sex couples, including bi-national couples. But beyond the benefits to married couples themselves, the Court’s decision is also a win for economic competitiveness. Specifically, the DOMA ruling makes U.S. businesses more globally competitive because they now can attract and retain foreign-born employees who want to stay in the United States with their same-sex spouses.

USCIS Approves First Green Cards for Same Sex Couples
On June 26, the Supreme Court issued its decision in the case of United States v. Windsor, in which it struck down section 3 of the Defense of Marriage Act (DOMA), which defined marriage as between a man and a woman for all federal laws. This law meant that the immigration agencies would not recognize lawful, same-sex marriages for any immigration purpose. Since the Court’s decision, the Obama administration has moved rapidly to allow U.S. citizens to petition for immigration benefits for their spouses, providing hope to an estimated 28,500 bi-national same-sex couples in the United States who might otherwise be separated by our immigration laws.

Supreme Court Strikes Down DOMA, Affirms Immigration Rights of Gay and Lesbian Couples
Today, the Supreme Court issued its decision in the case United States v. Windsor, striking down section 3 of the Defense of Marriage Act, or DOMA, on the basis that it violated equal protection under the due process clause of the 5th Amendment. DOMA established an exclusively heterosexual definition of “marriage,” and denied same-sex couples any federal benefits, including immigration benefits. This is a historic day for gay and lesbian marriage rights, as DOMA disqualified same-sex couples from over a thousand federal benefits, and made same-sex couples in committed relationships second-class citizens in the eyes of the federal government.

Crafting a Successful Legalization Program: Lessons From the Past
One of the themes that emerged from the Senate Judiciary Committee mark up of the 2013 Senate immigration bill was the necessity of avoiding the mistakes of the past. In the context of legalization for the 11 million unauthorized immigrants now in the United States, the argument is often made that the 1986 law wasn’t tough enough, and any new legalization program should have more requirements and restrictions. However, in my 39-year career with the Department of Homeland Security (DHS) and former Immigration and Naturalization Service (INS), and after years of studying implementation of the 1986 law, I’ve reached a different conclusion. A successful legalization program depends on simplicity and common sense. There are many lessons to be learned from the 1986 law about how to design a better legalization program. Fortunately, many of those lessons have been absorbed by the drafters of S. 744, the Border Security, Economic Opportunity and Immigration Modernization Act. Nonetheless, as the debate continues on this bill, it is important to reiterate the importance of good design and thoughtful implementation. That is what will ensure success and provide the country with a working immigration system. Read More
Medicare’s Health and Well-Being Depends on Immigrants
Immigrants’ access to affordable health care is one of the most contested issues in the current immigration reform debate. Most advocates of comprehensive immigration reform point to the need to ensure that aspiring citizens have opportunities to access appropriate health care since such access will impact their ability to learn, to work, and to contribute to their communities. On the other end of the spectrum, anti-immigration groups tend to inaccurately emphasize that newly legalized immigrants would represent an excessive fiscal burden. This prediction is based on a misleading characterization of immigrants as “takers”—in other words, as disproportionate consumers of public resources. Several studies have shown that this is just not the case. In fact, non-citizens use public benefit programs at a lower rate than similar low-income native-born citizens. With regard to medical expenditures in particular, immigrants tend to use less health care than their U.S.-born counterparts. Read More
Passport Pages Tell Our Tale
Today in the United States, Lesbian, Gay, Bisexual, and Transgender (LGBT) Americans who fall in love with and marry foreign nationals are being asked to choose between country and spouse, country and career, and country and family. I know this because I have spent the last several years in a battle with my own government to recognize my wife for immigration purposes. Trying to keep my marriage to a British national together has cost me my career and a full pension, time away from my American family and friends, as well as a great deal of stress over finances and my future. Gay Americans who are legally married in the U.S. have a marriage that is not recognized by the federal government. Therefore, the 28,500 same-sex binational couples in America, in which one spouse is an American citizen, are in a situation where they cannot sponsor their husbands and wives for immigration purposes. This also means they do not receive the 1,138 federal rights, benefits, protections, and obligations that automatically come with marriage and serve to protect and support families. Read More
Former Bush Administration Official Explains Why Immigration Bill Is Good For The Economy
Following the introduction of the Senate immigration reform bill earlier this week, the Senate Judiciary Committee held its first hearing about the measure today. It gave the senators a chance to air their various complaints about the bill – that it does not protect LGBT couples or that the bill micro-manages the hiring process for foreign workers – but largely, committee members asked about the ways immigration reform will impact the U.S. economy, from the agriculture industry to high-skilled industries.
