One definition, two programs. The term "refugee" is defined once in United States immigration law, at 8 U.S.C. § 1101(a)(42), which is section 101(a)(42) of the Immigration and Nationality Act. That single definition supplies the substantive test for two different programs: admission as a refugee from abroad under 8 U.S.C. § 1157, and asylum for a person who is already in the United States under 8 U.S.C. § 1158. The procedures, the forms and the decision makers differ. The underlying question of who counts as a refugee does not.
The statutory text. The definition reads as follows.
(A) any person who is outside any country of such person's nationality or, in the case of a person having no nationality, is outside any country in which such person last habitually resided, and who is unable or unwilling to return to, and is unable or unwilling to avail himself or herself of the protection of, that country because of persecution or a well-founded fear of persecution on account of race, religion, nationality, membership in a particular social group, or political opinion, or (B) in such special circumstances as the President after appropriate consultation (as defined in section 1157(e) of this title) may specify, any person who is within the country of such person's nationality or, in the case of a person having no nationality, within the country in which such person is habitually residing, and who is persecuted or who has a well-founded fear of persecution on account of race, religion, nationality, membership in a particular social group, or political opinion.
The term "refugee" does not include any person who ordered, incited, assisted, or otherwise participated in the persecution of any person on account of race, religion, nationality, membership in a particular social group, or political opinion. For purposes of determinations under this chapter, a person who has been forced to abort a pregnancy or to undergo involuntary sterilization, or who has been persecuted for failure or refusal to undergo such a procedure or for other resistance to a coercive population control program, shall be deemed to have been persecuted on account of political opinion, and a person who has a well founded fear that he or she will be forced to undergo such a procedure or subject to persecution for such failure, refusal, or resistance shall be deemed to have a well founded fear of persecution on account of political opinion.
Two branches, and only one of them supports asylum. Subparagraph (A) covers a person who is outside the country of nationality or, for a person with no nationality, outside the country of last habitual residence. Subparagraph (B) covers a person who is still inside that country, and it operates only where the President has designated a category of such persons in special circumstances after consultation with Congress. Asylum runs solely on the first branch: both the eligibility provision at 8 U.S.C. § 1158(b)(1)(A) and the burden of proof provision at 8 U.S.C. § 1158(b)(1)(B)(i) refer specifically to 8 U.S.C. § 1101(a)(42)(A). The second branch belongs to the refugee admissions program and is not available to a person applying for asylum.
Five grounds, and a required connection. Race, religion, nationality, membership in a particular social group and political opinion are the only protected grounds, and the harm must be connected to one of them. For asylum the connection is stated expressly: 8 U.S.C. § 1158(b)(1)(B)(i) requires the applicant to establish that a protected ground was or will be at least one central reason for the persecution. Harm that is genuine but untethered from those five grounds, such as a private feud, ordinary crime, generalized disorder or economic hardship, does not meet the definition however severe it is.
Past persecution and well-founded fear are alternatives. The regulation at 8 C.F.R. § 208.13(b) draws out what the statutory phrase implies: a person may qualify either by having suffered persecution in the past or by holding a well-founded fear of persecution in the future. Under 8 C.F.R. § 208.13(b)(1), an applicant who establishes past persecution on a protected ground is presumed to have a well-founded fear on the basis of the original claim, and the burden shifts to the government to rebut that presumption.
What makes a fear well founded. Under 8 C.F.R. § 208.13(b)(2)(i) the fear must be genuinely held, there must be a reasonable possibility of suffering persecution on return, and the person must be unable or unwilling to return to the country or to seek its protection because of that fear. The measure is a reasonable possibility rather than a probability. Two qualifications follow. Under 8 C.F.R. § 208.13(b)(2)(ii) there is no well-founded fear where persecution could be avoided by relocating within the country and relocation would be reasonable under all the circumstances. Under 8 C.F.R. § 208.13(b)(2)(iii) an applicant who establishes a pattern or practice of persecution of a similar group need not prove that he or she would be singled out individually.
Inability or unwillingness to seek national protection. The definition asks two things at once: that the person be unable or unwilling to return, and that the person be unable or unwilling to call on the protection of the country in question, in each case because of persecution or a well-founded fear of it. That second requirement, rather than any separate provision, is the textual foothold for claims founded on harm inflicted by private hands, because it directs attention to whether the country will actually furnish protection and not only to whether its officials caused the harm.
The persecutor exclusion sits inside the definition. The second sentence of 8 U.S.C. § 1101(a)(42) removes from the term anyone who ordered, incited, assisted or otherwise participated in the persecution of another person on a protected ground. Because it is written into the definition itself, it is not a discretionary factor to be weighed against sympathetic facts. The same conduct reappears as a bar to asylum at 8 U.S.C. § 1158(b)(2)(A)(i) and as a bar to withholding of removal at 8 U.S.C. § 1231(b)(3)(B)(i).
Coercive population control. The third sentence deems a person to have been persecuted on account of political opinion where that person has been forced to abort a pregnancy or to undergo involuntary sterilization, or has been persecuted for refusing or otherwise resisting such a program, and it treats a well-founded fear of the same treatment in the same way. A numerical limit once applied to this ground: former 8 U.S.C. § 1157(a)(5) capped at 1,000 per fiscal year the number of persons who could be admitted or granted asylum on the strength of it. Congress struck that paragraph in 2005 in the REAL ID Act, Public Law 109-13, and no such cap applies now.
The hardest terms are left undefined. Neither "persecution" nor "membership in a particular social group" is defined in the statute, and the asylum regulations in 8 C.F.R. part 208 do not define them either. Their content comes from administrative and judicial decisions, which is why applicants with similar histories can meet different outcomes depending on when and where a case is decided. Formulating a particular social group is the point at which many otherwise sympathetic claims fail.
Related protections use different tests. Withholding of removal under 8 U.S.C. § 1231(b)(3)(A) does not use the refugee definition at all. It asks whether life or freedom would be threatened on account of one of the same five grounds, and 8 C.F.R. § 208.16(b)(2) sets that standard at more likely than not, a heavier burden than a reasonable possibility. Protection under the Convention Against Torture is different again, turning on the likelihood of torture rather than on any protected ground.
The definition keeps working after a grant. Satisfying it once does not settle matters permanently. Asylum status may be terminated where the person no longer meets the conditions owing to a fundamental change in circumstances, under 8 U.S.C. § 1158(c)(2)(A). An asylee who later applies for permanent residence must, under 8 U.S.C. § 1159(b)(3), continue to be a refugee within the meaning of 8 U.S.C. § 1101(a)(42)(A), or be the spouse or child of such a person, at the time of that application.
