Technology & Infrastructure

A new border architecture has emerged that seeks to respond effectively to the seemingly competing demands of facilitating mobility while better managing the risks associated with cross-border travel (terrorism, organized crime, and the entry of unwanted migrants). Information and technology are the centerpieces of this new architecture. This research explores the increased collection and sharing of traveler and other data, expanded use of interoperable information databases, and the new border-management technologies and infrastructure used at ports of entry and beyond.

Donald Trump has made a series of postelection statements suggesting he may backtrack on several campaign pledges on immigration, including building a wall across the entire U.S.-Mexico border and deporting all 11 million unauthorized immigrants.
