More than 4 million Syrians have fled their country since the start of the Syrian civil war.
"I know people don't like this answer, but it takes a long time the US resettlement program to get moving," Gauger said of US responsibility for resettling Syrian fleeing violence.
"It is now getting moving for Syrians," she said, noting that in the next five years "I am sure that we would have admitted tens and tens of thousands of Syrian refugees."
Gauger explained that the US program for resettling Iraqis only got started in 2007 or 2008, four years after the US military invasion of the country.
Since 2007, the United States has resettled more than 126,000 Iraqi refugees, according to the State Department Bureau of Population, Refugees and Migration.
