a wall can't stop that
A new Department of Homeland Security report released Monday found that in 2016, more than 600,000 foreigners who entered the U.S. legally overstayed their visas, with some just one day over their limit and others never planning on leaving.
The report says that of the 50 million travelers who came to the U.S. in 2016 via air and sea, 1.25 percent overstayed their visas; they make up 40 percent of the estimated 11 million undocumented immigrants in the United States, USA Today reports. The Department of Homeland Security released its first report on visa overstays in January 2016, and found that in 2015, 347,632 foreigners who arrived in the U.S. through the Visa Waiver Program, B-1 business visas, or B-2 tourism visas remained in the United States after their visa expired, and that number increased by 13 percent in 2016.
"Identifying overstays is important for national security, public safety, immigration enforcement, and processing applications for immigration benefits," the report said.
