Asylum seekers hoping to enter the United States will be required to wait in Mexico while their claims are processed, according to a new deal reportedly struck between the Trump administration and Mexicos incoming government.

Quoting senior members of President-elect Andrs Manuel Lpez Obradors team, the Washington Post reports that while a formal agreement has yet to be signed, the Remain in Mexico plan will prevent those seeking asylum from stepping onto U.S. soil until their applications are approved.

The deal marks a dramatic change in government policy, which currently allows those seeking asylum to remain in the U.S. while awaiting the decisions on their applications.
