The State Department works with nine agencies to place refugees around the country, six of which are faith based. To be processed as a refugee, an individual has to meet the U.S. definition of “refugee” and be “among those refugees determined by the President to be of special humanitarian concern in the United States; not be firmly resettled in any third country; be otherwise admissible under U.S. laws.” There are caveats that can keep someone from being admitted, but if approved, agencies will then work with local churches to resettle refugees. World Relief, an Evangelical organization, is among them.

World Relief’s site says its mission is “to empower the local church to serve the most vulnerable.” Within the last 30 years, the group has helped more than 250,000 refugees. Local churches are instrumental in the effort, since they’re tasked with welcoming and resettling a refugee in the community, a process that can take several months.

But a string of events last November prompted concerns around the country about the admittance of refugees. More than 30 governors—all of whom were Republican except one—said they would not allow Syrian refugees to be resettled in their states, following the Paris attack that left more than 120 people dead and scores of others injured. In its aftermath, officials said at least one of the suspects had ties to Syria.

While states do not have the authority to refuse refugees entry, calls to halt the resettlement of refugees in the United States sparked widespread concern. Republican presidential candidates began expressing their hesitations, arguing the system was flawed and vulnerable to terrorists. Among them was Trump, who touted a hardline stance on immigration throughout the presidential primary.

“We have no idea who these people are, we are the worst when it comes to paperwork.” he said. “This could be one of the great Trojan horses.” The debate over what to do about the Syrian refugee crisis also landed in Congress, where the House introduced legislation to curb the number of refugees coming to the United States from Syria and Iraq. Senate Democrats later blocked the bill.

The contentious nature of the issue has had implications at the local level. Some churches have become wary of admitting refugees amid the heated rhetoric. After all, Trump once proposed a temporary ban on Muslims entering the United States, but shifted his position this summer to say the ban should be based on territory. “We’ve been surprised how much vitriol [there’s been] against refugees in general,” Yang told me.

Hope Point Church in South Carolina knows it well. The church began working with World Relief to resettle refugees roughly two years ago. Since then, they’ve worked with a total of nine refugees from the Congo. But the events that occurred within the last year brought a “sense of concern” among the community, said Richard Smith, the lead pastor at Hope Point. South Carolina Governor Nikki Haley called on Secretary of State John Kerry to stop the resettlement of Syrian refugees due to concerns about the vetting process.
