After years of gridlock, increasing pressure from immigrant advocates, and several delays in 2014, President Obama announced sweeping executive actions to provide deportation relief to as many as 5.2 million unauthorized immigrants in the United States. The plan sparked a political firestorm among Republicans who vowed to use all tools at their disposal to block the actions, ensuring that immigration will continue to be a flashpoint for the remainder of the president's term.

New migration patterns at the U.S. Southwest border, including a shift in border crossers from primarily Mexican men to Central American families, and from the California and Arizona borders to the Rio Grande Valley, have important implications for U.S. border policy and enforcement strategies, raising questions of what consequences might deter unauthorized Central Americans while still meeting international obligations to protect vulnerable migrants.

In recent years emigration from Mexico has declined, the country's stable economy has drawn an increasing number of international migrants, and the pace of transmigration to the United States has quickened. Amid these changing realities, punctuated by a spike in migration of unaccompanied minors from Central America in 2014, Mexico is confronting a new role as migration manager: balancing increasing enforcement and protection of migrants' rights.
