• Extreme stress in childhood is toxic to your DNA

    The real danger of separating children from parents is not the psychological stress – it’s the biological time bomb. The screaming and crying, the anguish and desolation is gut-wrenching. But the fallout pales in comparison to the less visible long-term effects that are more sinister and dangerous.

  • How immigration court works

    Can the U.S. attorney general unilaterally overturn an immigration-court court case? Yes, because, as I teach my surprised law students, immigration judges are not part of the judicial branch. They are attorneys in the Department of Justice. That means normal assumptions about judicial independence and freedom from political influence do not apply in immigration proceedings.

  • Trump wants to prosecute all illegal border crossings without splitting up families. That will be a challenge.

    When President Donald Trump on Wednesday backed down from an immigration policy that separated migrant families, he pledged to continue his “zero tolerance” approach: Parents would still be prosecuted for illegally crossing the border, but their families wouldn’t be split up. But legal and logistical challenges will make it exceedingly difficult for his administration to accomplish both goals. To do so, federal agencies need to find space for thousands of children and adults as they await criminal and civil immigration proceedings. And another federal agency must find a way to do so without running afoul of the law.

  • Medical experts alarmed over impact of family separation on children

    Lat Thursday, thousands of medical experts and mental health professionals and researchers sent a letter to DHS secretary Kirstjen Nielsen and Attorney General Jeff Sessions calling for an immediate end to forced family separation at the border, citing concerns from the medical community over the trauma and potentially long-lasting damage it has on children’s health and well-being. “The United States should follow the “best interests of the child” standard and immediately stop the practice of forced separation. It should not be U.S. policy to traumatize children, especially not as a form of indirect punishment of their parents,” the mental health professionals wrote.

  • U.S. immigrant vetting system is already extreme enough: Study

    In the wake of the 9/11 attacks, the U.S. has tightened the vetting of immigrants and foreign travelers. The post-9/11 system has worked: From 2002 to 2016, the vetting system failed and permitted the entry of 1 radicalized terrorist for every 29 million visa or status approvals. Only 1 of the 13 post-9/11 vetting failures resulted in a deadly attack in the United States. Thus, the rate for deadly terrorists was 1 for every 379 million visa or status approvals from 2002 through 2016. During this same period, the chance of an American being killed in an attack committed by a terrorist who entered as a result of a vetting failure was 1 in 328 million per year.

  • For border security, CBP agents are more suitable than National Guard soldiers

    Rather than send the National Guard to bolster security along the U.S.-Mexico border, it would have been better, and more cost-effective, to send more Customs and Border Patrol agents, whose training makes them more suitable for border security-related missions. But the problem is that the hiring process of CBP agents is broken and unnecessarily lengthy, requiring a thoroughgoing reform.

  • Anti-immigrant prejudice linked to mortality risk

    One of the defining elements of the 2016 election cycle was its focus on immigration. One aspect of immigration did not figure in the discussion: When it comes to mortality, U.S.-born individuals of immigrant descent fare much worse than their foreign-born counterparts — but why?

  • MS-13 is a street gang, not a drug cartel – and the difference matters

    I spent three years at American University’s Center for Latin American and Latino Studies chronicling the MS-13’s criminal exploits for the National Institute of Justice. Our study proves that MS-13 is neither a drug cartel nor was it born of illegal immigration. That misconception is fueling failed U.S. policies that, in my assessment, will do little to deter MS-13.

  • Early Trump support increased in areas with recent Latino population growth: Study

    Donald Trump announced his presidential candidacy in June 2015 with a bold, double-edged promise: that he would build a “great wall” on the border separating the United States and Mexico, and that he would make Mexico pay for it. That polarizing statement, since repeated ad nauseam by commentators on both sides of the political spectrum, quickly went on to become one of the defining hallmarks of Trump’s presidential campaign. According to three political scientists from the University of California, Riverside, Trump’s remarks also galvanized his voter base in the initial stages of his campaign, particularly in areas that had experienced considerable Latino population growth in recent years.

  • Hotter temperatures will accelerate asylum-seekers migration to Europe

    New research predicts that migrants applying for asylum in the European Union will nearly triple over the average of the last fifteen years by 2100 if carbon emissions continue on their current path. The study suggests that cutting emissions could partially stem the tide, but even under an optimistic scenario, Europe could see asylum applications rise by at least a quarter.

  • With border arrests down, some question Trump administration's push for more agents

    The Department of Homeland Security’s announced this week a near-record decline in the number of people caught trying to enter the country illegally. Yet the Trump administration still wants to hire thousands of more border agents.

  • Climate changes triggered immigration to America in the nineteenth century

    From Trump to Heinz, some of America’s most famous family names and brands trace their origins back to Germans who emigrated to the country in the nineteenth century. Researchers have now found that climate was a major factor in driving migration from Southwest Germany to North America during the nineteenth century.

  • Germany’s newly elected populist, far-right AfD: We will fight an “invasion of foreigners”

    Leaders of the populist, nationalist AfD party, which entered the Bundestag for the first time after Sunday federal election, have pledged to fight an “invasion of foreigners” with its new MPs. Alexander Gauland, speaking in Berlin the morning after the election results came in, said his party would “uncompromisingly address” immigration, an issue the party has campaigned on since late 2015. “One million people – foreigners – being brought into this country are taking away a piece of this country and we as AfD don’t want that,” Gauland told a press conference late Sunday. “We say we don’t want to lose Germany to an invasion of foreigners from a different culture. Very simple.”

  • How “dreamers” and green card lottery winners strengthen the U.S. economy

    Those who wish to restrict immigration often cite what they naïvely call “supply-and-demand economics” to essentially argue that the economy is a fixed pie that gets divided among a country’s residents. Fewer immigrants means “more pie” for the U.S.-born, as the story goes. I am an economist, and this is not what my colleagues and I say. The commonplace argument that increases in the volume of immigration, by themselves, lower wages and take jobs from Americans – an argument which Attorney General Jeff Sessions used to defend ending DACA – has neither empirical nor theoretical support in economics. It is just a myth. Instead, both theory and empirical research show that immigration, including low-skill and low-English immigration, grows the pie and strengthens the American workforce.

  • UC sues DHS, calling DACA cancellation unconstitutional

    The University of California on Friday filed suit in federal court against the Trump administration for wrongly and unconstitutionally violating the rights of the University and its students by rescinding the Deferred Action for Childhood Arrivals (DACA) program on “nothing more than unreasoned executive whim.” UC President Janet Napolitano was secretary of DHS from 2009 to 2013, and created the DACA program in 2012.
