António Guterres, the UN high commissioner for refugees, has called on European Union countries to admit up to 200,000 refugees as part of a large-scale relocation program which would be mandatory for all EU states. Guterres said the EU was facing a defining moment and must “mobilize full force” toward a common approach to the migration crisis. Guterres’s appeal followed a joint call by France and Germany for binding EU quotas which would require all EU member states to share the burden of the influx of migrants and refugees. The wave of tens of thousands of refugees has hit Greece, Italy, and countries in south-eastern and central Europe especially hard.

This Thursday, the U.K. Office for National Statistics (ONS) will publish a new set of migration statistics. The data will cover many different topics, but two numbers are likely to attract attention: one relating to the “flow” of migrants in and out of the United Kingdom, the other relating to the “stock” of foreign-born people living in the United Kingdom. In the last quarter’s data, net migration was estimated to stand at 318,000 — just 2,000 below the highest level previous recorded in 2005. The U.K.’s foreign-born population is expected to exceed eight million for the first time in the published ONS data. Experts say that the more fundamental questions about migration policy successes and failures are more nuanced than a set of figures, and these questions include how immigration affects the U.K. labor market and whether it makes existing U.K. residents wealthier.

Arizona Sheriff Joseph Arpaio on Friday lost yet another round in his on-going battle against the Obama administration over immigration. The U.S. Court of Appeals for the D.C. Circuit, in Arpaio v. Obama, ruled unanimously that Arpaio did not have standing to sue. “We conclude that Sheriff Arpaio has failed to allege an injury that is both fairly traceable to the deferred action policies and redressable by enjoining them, as our standing precedents require,” Judge Nina Pillard wrote for the court. His allegations “are unduly speculative,” resting on “chains of supposition and contradict acknowledged realities.”

Citizens of the thirty-eight countries which are part of the U.S. Visa Waiver Program may travel to the United States without having to obtain an entry visa if they plan to stay in the United States for a period not exceeding ninety days, and if they meet the requirements. Last Thursday, the Department of Homeland Security announced that it would tighten the security measures which are already part of the program, and add additional security measures to it.

When President Barack Obama last year issued his Deferred Action for Childhood Arrivals (DACA) executive order, applicants covered by the order received a three-year work permit, or EADs (Employment Authorization Documents). On 16 February 2015, Brownsville, Texas-based U.S. District Judge Andrew Hanen temporarily blocked Obama’s immigration action. After the temporary injunction was in place, the federal government mistakenly issued the approximately 2,500 three-year permits. On Friday, DHS secretary Jeh Johnson asked Judge Hanen not to find him and other Obama administration officials in contempt, telling the judge that DHS had recovered all but 22 of the 2,500 offending permits. Johnson also advised the judge that DHS had corrected federal computer databases to invalidate those permits not turned over by their owners.

A U.S. Government Accountability Office (GAO) audit says U.S. Border Patrol agents were in violation of agency rules when, between 2009 and 2014, they deported thousands of unaccompanied immigrant children. The GAO said that Customs and Border Protection (CBP) repatriated 93 percent of unaccompanied children under age 14 from Mexico and Canada – and did so without documenting what procedures they followed to ascertain that the children would be safe when they return to their home countries.

A just-published report by the American Immigration Council says that many studies have confirmed two simple but compelling truths about the relationship between immigration and crime: immigrants are less likely to commit serious crimes or be behind bars than the native-born, and high rates of immigration are associated with lower rates of violent crime and property crime. This holds true for both legal immigrants and the unauthorized, regardless of their country of origin or level of education. These facts notwithstanding, the report says, immigration policy is frequently shaped more by fear and stereotype than by empirical evidence, leading to the stigma of “criminality” ascribed to immigrants by an ever-evolving assortment of laws and immigration-enforcement mechanisms. The result is an immigration policy which “is cruel, pointless, shortsighted, and counterproductive. And it is not an effective substitute for immigration reform which makes our immigration system responsive to the economic and social forces which drive migration in the first place,” the report concludes.

After visiting a family detention center in Texas, U.S. Homeland Security Secretary Jeh Johnson announced Wednesday that families who enter the country illegally to seek asylum will no longer be detained after they’ve established legitimate claim for relief. Johnson said that the Department of Homeland Security is making “substantial changes” to its detention practices so that families with children are not unnecessarily kept locked up.

It has been more than a year since James F. Tomsheck, the senior executive at Customs and Border Protection Internal Affairs (CBP IA), was unceremoniously reassigned to a new position at CBP. In response to his demotion from assistant commissioner at CBP IA, Tomsheck lambasted CBP leadership with charges of rampant mismanagement and accused CBP employees of widespread violence and corruption. Have these systemic problems within the largest federal law enforcement agency in the land been resolved, or have the FBI, CBP, and DHS senior leadership chosen to ignore these problems? Is there reasonable public accountability for the alleged criminal behavior at CBP and CBP IA, or are the alleged victims — all the honest, hardworking CBP employees, and the general public — still in the dark about both the hard facts and the consequences of this unprecedented scandal? In short, has there been a clean-up or a cover up?
