From the Miami Herald:

The bipartisan immigration proposal filed this month in the Senate would create a 24/7 surveillance system at U.S. borders that would rely significantly on increased use of drones. Under the bill, no immigrant with provisional legal status could apply for a green card if the Department of Homeland Security hasn’t effectively secured the border – a benchmark that border hawks want tied to citizenship. And to do that, the bill recommends increasing the use of unmanned aircraft, remotely controlled by crews miles away and tasked with what U.S. Customs and Border Protection has characterized as scouting out “potential terrorist and illegal cross-border missions.”
