The Homeland Security Department has lost track of more than 1 million people who it knows arrived in the U.S. but who it cannot prove left the country, according to an audit Tuesday that also found the department probably won’t meet its own goals for deploying an entry-exit system.
The findings were revealed as Congress debates an immigration bill, and the Government Accountability Office’s report could throw up another hurdle because lawmakers in the House and Senate have said that any final deal must include a workable system to track entries and exits and cut down on so-called visa overstays.
The government does track arrivals, but is years overdue in setting up a system to track departures — a goal set in a 1996 immigration law and reaffirmed in 2004, but which has eluded Republican and Democratic administrations.
