Unaccompanied child immigrants from Central America have poured across the southern U.S. border in recent months. Mostly spurred by violence and poor economic conditions in Central America, the migrants also believe changes in U.S. immigration policy will allow them to stay.

They aren’t completely wrong. Because border facilities are so overwhelmed, authorities often release children into the care of relatives already in the U.S. and allow mothers with children to enter the country with a notice to appear in immigration court. Detentions of unaccompanied minors at the U.S. border have more than tripled since 2011, the Associated Press reports.

Government officials have hotly debated what to do with the increasing number of Central American migrants, but no easy solution has been found.
