As we have explained before, the only thing close to a 200,000 figure is an announcement in September by Secretary of State John Kerry that the United States was prepared to boost the number of total refugees accepted from around the world in fiscal 2016, from 70,000 to 85,000. Then, in 2017, Kerry said that 100,000 would be accepted.

That adds up to 185,000 over two years. But this would be the total number of refugees, not the number of refugees from Syria.

By law, the president every fiscal year sets the maximum number of refugees the United States can accept in a year. (Note to Carson: This is not done by executive order; it is a legal requirement.) Over the past decade, the annual limit has been between 70,000 and 80,000, according to the Congressional Research Service. (In fiscal 2013, about 30 percent came from the Middle East, mostly from Iraq.) So, 100,000 from around the world in 2017 would be a big jump, assuming Obama goes through with the pledge to authorize that level. But nothing is set in stone.

As for Syria, Obama has only directed the United States to accept at least 10,000 Syrian refugees in the next year.
