Who is eligible to occupy what office is determined by which set of facts one uses or subscribes to.
Like wise, how the refugee resettlement policies work depend on which set of facts you use.
Gov Haley uses a set of facts that are easily found, that involve congress, the prez, the federal agencies, the voluntary agencies(NGOs), the criteria used, etc. For example: religion is not used as criteria in refugee resettlement.
OTOH, there is a second set of facts surrounding refugees which is used by most freepers, World Net Daily, Sen Jeff Sessions, etc. These are the facts that come from Ann Corcoran and Resettlement Watch. For example: Obama wants to allow only Muslim refugees.
