Refugee resettlement is handled by the federal government, which determines how many refugees will be admitted and from where.

"These states cannot do anything with regards to federal immigration law," Mo Idlibby, a Syrian-born immigration attorney in Charlotte, North Carolina, told WSOC-TV. "You say, 'OK, so where's the substance in what you are talking about?' There is none."

When it comes to finding housing for those refugees, that's handled by volunteer agencies, which receive funding from the Department of State or are self-funded. (Video via Catholic Community Services of Utah)

In fact, if governors try to stop refugee settlement, either by trying to block their admission into the state or by blocking their housing, that could violate the 14th Amendment, as well as a mountain of legal precedents and Supreme Court rulings, according to University of Connecticut law professor Jon Bauer.

Governors can lobby members of Congress to enact legislation to limit or stop the admission of Syrian refugees, and Sen. Rand Paul has already introduced a bill that would do that. (Video via The White HouseOffice of Sen. Rand Paul)

But it's unlikely such a bill would make it through both houses of Congress, and even more unlikely it would have the support needed to override a probable presidential veto.

"If we have no information on someone, they've never crossed our radar screen, never been a ripple in the pond, there will be no record of them there. It will be challenging," Comey said.

But that's hardly unique to Syrian refugees. In fiscal year 2014, the U.S. accepted 9,000 refugees from another war-torn country with an active terror group: Somalia.
