Refugees who were slated to travel to the United States after a years-long and often cumbersome process have had their flights canceled, according to a State Department memo to resettlement partners obtained by CNN.

The decision leaves refugees who have completed a lengthy process stranded abroad and facing extended separation from loved ones already in the U.S.

The Trump administration has canceled travel plans for refugees who have already been cleared to come into the United States. The Associated Press reported that the refugees had been approved to come here before a deadline next week suspending America’s refugee resettlement program.
