The Berduo family traveled nearly 2,000 miles from Guatemala to the international bridge between Matamoros, Mexico, and Brownsville, Texas, but they could go no further.
Under a new policy, federal border agents stationed in the middle of international bridges are turning away asylum seekers like the Berduos, telling them there is no room in U.S. Customs and Border Protection stations for them.
