A new immigration bill introduced by Sen. John Cornyn (R-Texas), which is currently posted on his website, would significantly expand surveillance along the U.S.-Mexico border and potentially increase the use of biometric data and drones, according to a report by The Hill.

Released last week, the bill includes several provisions that would alter the country’s existing border security policy.

One of the provisions calls for the implementation of a “biometric exit data system” at the nation’s 15 busiest international airports which would “match biometric information for an alien who is departing the United States against the biometric information obtained for the alien upon entry to the United States.”

In addition, the bill requests the use of unmanned drones to monitor the border for at least 24 hours a day, five days a week as part of an overall goal to provide “continuous surveillance.”

Another key provision requires the Department of Homeland Security to be given access to a facial recognition system for “the greatest extent practicable … inspect[ing] travelers at United States airports of entry.”
