Under federal law, the executive branch is expressly required to take religion into account in determining who is granted asylum.
Under the provision governing asylum (section 1158 of Title 8, U.S. Code), an alien applying for admission must establish that ... religion... was or will be at least one central reason for persecuting the applicant.
Moreover, to qualify for asylum in the United States, the applicant must be a 'refugee' as defined by federal law. That definition (set forth in Section 1101(a)(42)(A) of Title , U.S. Code) also requires the executive branch to take account of the alien's religion: The term 'refugee' means (A) any person who is outside any country of such person's nationality ... and who is unable or unwilling to return to ... that country because of persecution or a well-founded fear of persecution on account of ... religion ...[.]

In the case of this war, the Islamic State is undeniably persecuting Christians.
