After years of limbo on Manus Island and Nauru, refugees will soon know whether they will be moving to the US to start a new life.
US authorities will begin handing out resettlement decisions from Wednesday and Thursday on both Pacific islands.
Some refugees received appointment slips on Tuesday afternoon.
"People are a bit surprised, some people had given up hope that it would happen," Refugee Action Coalition spokesman Ian Rintoul told AAP.
"Right now they're experiencing anxiety and anticipation."
