National Guard Heads to Southern Border Amid Differing Reality from Earlier Deployments

Seizing on reports of a migrant “caravan” making its way northward through Mexico, President Donald Trump called for up to 4,000 National Guard troops to deploy to the Southern border. Although previous presidents took similar action in response to upticks in violence and apprehensions, the picture at the border today differs on several metrics.

The Trump administration has been steadily building a case to penalize "sanctuary" cities—those jurisdictions that in some way limit their cooperation with federal immigration authorities—after threatening to cut federal funding. Despite court rulings that seemed to strike a blow against these efforts, the Justice Department is moving forward with its strategy, relying on a broad interpretation of a federal statute, as this article explores.

The fate of the Deferred Action for Childhood Arrivals (DACA) program has ping ponged between all three branches of government.

Legal Migration for Work and Training: Mobility Options to Europe for Those Not in Need of Protection

As EU Member States struggle to deliver on the European Union's call to expand channels for foreign workers, they should focus more on attracting the middle- and low-skilled third-country nationals needed by the labor market yet for whom few opportunities for admission exist.
