Jolie said they are still working out the details for her new role, which may include special envoy on the refugee crisis affecting Afghans fleeing for Pakistan and Iran.
"We are looking at a few countries in the world," Jolie asid. "We're hoping to discuss it in the next few weeks but we want to research it properly."
Jolie has visited dozens of countries during her 10 years as a goodwill ambassador. She described her work with the U.N. as "moving, sometimes heartbreaking, but always rewarding and unforgettable."
