Petitioner Awa Niang is a victim of female genital mutilation (FGM). She faces *1191 removal from this country because she overstayed her nonimmigrant visa, was working in the United States without permission of the Immigration and Naturalization Service (INS), 1 and had falsely represented herself as a citizen to obtain employment. To avoid being returned to her native Senegal, she sought asylum and restriction on removal on the ground that she had suffered past persecution— FGM — in Senegal. She also sought relief under the Convention Against Torture (CAT), 2 on the ground that she was likely to be tortured if returned to Senegal.
The immigration judge (IJ) who conducted her hearing found that she had not been subjected to past persecution because he disbelieved her account of how the FGM occurred. The Board of Immigration Appeals (BIA) affirmed on the same ground. Ms. Niang’s claims for asylum and restriction on removal, however, do not rest solely on her narrative of the specific circumstances of the mutilation. She has consistently, although with less-than-optimal clarity, contended that she suffered FGM on account of her being a female member of the Tukulor Fulani tribe. Neither the IJ nor the BIA addressed this contention, much less explained why it was rejected. We therefore reverse the denial of asylum and restriction on removal, and we remand for further proceedings. We affirm the denial of relief under the CAT.
1. BACKGROUND
A. Ms. Niang’s Account
The following summarizes the documents and testimony supporting Ms. Niang’s claims for relief. She was born into the Tukulor Fulani tribe in Senegal in 1970. Her family is Muslim and believes in rigid adherence to certain gender roles and expectations. There was a strict separation between the men and women in her household, which included her parents, eight siblings, some cousins, and their spouses. Her family believed that women should not look at men, that family members should not display affection toward one another, and that women should obey their husbands.
According to tribal custom, when Ms. Niang was born she was promised in marriage to her cousin Daud, a man her father’s age who had three other wives. Because she was considered married to Daud, she was not allowed to date other men. Although most Tukulor Fulani girls were subjected to FGM and consummated their marriages when they were 10 to 12 years old, Ms. Niang refused to do so and her family acquiesced in her wishes, believing she would eventually change her mind. Unlike most Tukulor Fulani women, Ms. Niang was permitted to attend school at age 12.
When Ms. Niang was nearly 25, her family had a meeting in which they decided that she must consummate her mar *1192 riage with Daud that evening. She again refused, and her family threw themselves on her, stripping her of her clothes, beating her, and burning her with a hot iron. Some then performed FGM on her “[s]o that [she] wouldn’t be able to commit adultery and so that no one would want to have anything to do with [her]. And then she would be ashamed to show [her] body in front of another man.” Testimony of Ms. Niang, R. at 188. She left her house the next morning. For the next four years she stayed at her friend Maria’s house in another town while attending the university to obtain her Senegalese law license. She had no contact with her family during this time.
Ms. Niang came to the United States in 1999 and stayed with friends in Denver. Although she “wanted to live in a country where [she] could feel free,” and she still feared her family, id. at 194, she did not immediately seek asylum but entered as a nonimmigrant visitor, authorized to stay only until June 24, 2000. She met Elhadji Fall and married him on April 17, 2000. Because of her FGM, however, they could not have normal sexual relations and they separated. During her marriage Ms. Niang’s Senegalese friend Maria wrote her a letter informing her that her family considered her an adulteress because of her marriage to Fall and would kill her if she returned. According to Ms. Niang, if she was returned to Senegal, her family was “ready” and “waiting for [her],” and it would be “the end of [her] days.” R. At 204-05.
B. Removal Proceedings
The INS apprehended Ms. Niang while she was working as a security screener at the Denver International Airport. It initiated removal proceedings against her for (1) staying in the country longer than permitted, Immigration and Nationality Act (INA) § 237(a)(1)(B), 8 U.S.C. § 1227(a)(1)(B); (2) failing to comply with the conditions of her nonimmigrant status by working, INA § 237(a)(1)(C), 8 U.S.C. § 1227(a)(1)(C); and (3) falsely representing herself as a citizen of the United States to gain employment, INA § 237(a)(3)(D), 8 U.S.C. § 1227(a)(3)(D). She contested the factual basis of the removal charges, but the IJ found her removable on all three grounds. She then requested either (1) asylum under INA § 208, 8 U.S.C. § 1158; (2) restriction on removal under INA § 241(b)(3), 8 U.S.C. § 1231(b)(3); (3) relief from removal under the CAT, or (4) voluntary departure under INA § 240B, 8 U.S.C. § 229c.
At the asylum hearing Dr. Judith Wilson testified that Ms. Niang had been a victim of FGM, that her “normal anatomy ... had been obliterated essentially to the extent that her ability to engage in normal sexual intercourse was virtually impossible,” that she would probably not be able to conceive children naturally, and that she would not be able to deliver children vaginally. R. at 239-240. Judging from the scar tissue, Dr. Wilson estimated that the mutilation must have occurred at least three or four years before Ms. Niang’s 1999 examination, and it could have been performed as early as her late teens. In a letter from Dr. Wilson to Ms. Niang’s attorney that was admitted into the record, Dr. Wilson wrote that Ms. Niang told her that the beating and genital mutilation occurred in her late teens.
Ms. Niang also showed several burn scars to the IJ, and Dr. Wilson testified that the scars were consistent with her proffered account of her beating by her family. Finally, Dr. Wilson testified that the FGM did not look like a “medical[ly] oriented procedure” and agreed with the description that “the lady was butchered.” Id. at 247.
*1193 The IJ found that “[t]he evidence considered as a whole clearly shows that the respondent has suffered FGM in the past,” id. at 60, that according to the background material the FGM was most likely “excision,” id. at 59; and that “in Senegal 80 percent of the women will undergo that form of FGM,” id. (The IJ apparently confused the statistics for FGM victims in Senegal and Sierre Leone. According to the 1997 United States Department of State Report entitled “Female Genital Mutilation” (which appears in the record), Sierre Leone had an 80-90% victimization rate at that time, while Senegal’s was only 20%.) Ms. Niang’s membership in the Tu-kulor Fulani tribe is not disputed. But the IJ did not find Ms. Niang credible for several reasons: (1) she lied to gain employment; (2) on her asylum application she listed her parents’ address as her address from 1978 to 1999, but she testified that she had fled her parents’ home in 1995 after the alleged attack occurred; (3) she could name only two of the five pillars of Islam, despite her characterization of her family as Islamic extremists; (4) he did not understand why she did not undergo the mutilation before age 13, as her sisters had; and (5) Dr. Wilson’s letter was inconsistent with Ms. Niang’s testimony that the attack occurred when she was 25. Because the IJ found Ms. Niang’s account of how the genital mutilation occurred not credible, he denied her petitions for asylum, restriction on removal, and relief under the CAT.
Ms. Niang appealed to the BIA. The BIA affirmed the IJ’s decision and dismissed the appeal through an order written by a single board member. See 8 C.F.R. § 1003.1(e)(5)(2003) (under new streamlining procedures one member of board can address decision on the merits unless criteria require review by three-member panel). The BIA summarized the IJ’s reasons for finding Ms. Niang’s testimony not credible, and concluded that she had not demonstrated that the adverse credibility ruling was clearly erroneous. See 8 C.F.R. § 1003.1(d)(3)(i) (IJ’s credibility findings reviewed under elearly-erroneous standard). In reference to the undisputed genital mutilation, the BIA stated:
We also acknowledge that the respondent has undergone FGM, has other scarring, and that the practice of FGM can provide the basis for an asylum claim. Yet, we have not held that all instances of FGM will constitute past persecution and we decline to find that this respondent’s FGM constituted persecution due to her incredible testimony regarding the circumstances surrounding the FGM.
R. at 2 (internal citations omitted). Ms. Niang appeals this decision, contending that (1) the BIA erred in affirming the IJ’s adverse credibility finding and (2) her undisputed genital mutilation constitutes past persecution on account of membership in a social group regardless of how it occurred. We exercise jurisdiction under 8 U.S.C. § 1252(a),
see Tsevegmid v. Ashcroft,
II. DISCUSSION
A. Overview of Applicable Law
There are three avenues of relief for an alien who fears persecution if returned to a particular country. Under the INA a grant of asylum permits the alien to remain in this country and a restriction on removal forbids removal to the country where persecution may occur.
Wiransane v. Ashcroft,
1. Asylum
To be eligible for a discretionary grant of asylum, an alien must be a refugee. 8 U.S.C. § 1158(b)(1);
see Elzour v. Ashcroft,
any person who is outside any country of such person’s nationality ... 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.
8 U.S.C. § 1101(a)(42)(A). This definition is taken from the 1967 United Nations Protocol Relating to the Status of Refugees (the Refugee Protocol), ratified by the United States in 1968.
3
A primary purpose for which Congress adopted this definition in 1980 was “to bring United States refugee law into conformance with the [Refugee Protocol].”
INS v. Cardoza-Fonseca,
The governing regulation provides two ways of achieving refugee status: one based on past persecution and the other based on a well-founded fear of future persecution. See 8 C.F.R. § 1208.13(b)(2001). Our focus in this case is on past persecution. The regulation states:
An applicant shall be found to be a refugee on the basis of past persecution if the applicant can establish that he or she has suffered persecution in the past in the applicant’s country of nationality [on one of the forbidden grounds] ..., and is unable or unwilling to return to, or avail himself or herself of the protection of, that country owing to such persecution.
Id. §
1208.13(b)(1) (emphasis added).
See
63 Fed.Reg. 31,945; 31,946 (June 11, 1998) (explaining that amended regulation effective January 5, 2001, “leaves intact the important principle that an applicant who has established past persecution on account of one of the five grounds is a refugee”). The persecution must have been “imposed by the government or by groups which the government is unwilling or unable to control”.
Vatulev v. Ashcroft,
Refugee status does not, however, entitle the applicant to a grant of asylum; that decision continues to remain within the Attorney General’s discretion.
See Cardoza-Fonseca,
2. Restriction on Removal
To obtain a restriction on removal, an applicant must show that his “life or freedom would be threatened in that country because of the alien’s race, religion, nationality, membership in a particular social group, or political opinion.” 8 U.S.C. § 1231(b)(3)(A). The Attorney General may not remove an alien who establishes “a clear probability of persecution in the country to which he would be returned.”
Wiransane,
(1) Past threat to life or freedom, (i) If the applicant is determined to have suffered past persecution in the proposed country of removal on account of race, religion, nationality, membership in a particular social group, or political opinion, it shall be presumed that the applicant’s life or freedom would be threatened in the future in the country of removal on the basis of the original claim. This presumption may be rebutted if an asylum officer or immigration judge finds by a preponderance of the evidence:
*1196 (A) There has been a fundamental change in circumstances such that the applicant’s life or freedom would not be threatened on account of any of the five grounds mentioned in this paragraph upon the applicant’s removal to that country; or
(B) The applicant could avoid a future threat to his or her life or freedom by relocating to another part of the proposed country of removal and, under all the circumstances, it would be reasonable to expect the applicant to do so.
8 C.F.R. § 1208.16(b)(1).
3. Convention Against Torture
The CAT prohibits the return of an alien to a country where “it is more likely than not that he or she would be tortured.” 8 C.F.R. § 1208.16(c)(2). “A claim under the CAT differs from a claim for asylum or withholding of removal under the INA because there is no requirement that the petitioner! ] show that torture will occur on account of a statutorily protected ground.”
Cruz-Funez v. Gonzales,
any act by which severe pain or suffering, whether physical or mental, is intentionally inflicted on a person for such purposes as obtaining from him or her or a third person information or a confession, punishing him or her for an act he or she or a third person has committed or is suspected of having committed, or intimidating or coercing him or her or a third person, or for any reason based on discrimination of any kind, when such pain or suffering is inflicted by or at the instigation of or with the consent or acquiescence of a public official or other person acting in an official capacity.
8 C.F.R. § 1208.18(a)(1) (1999). Under the CAT future torture is not presumed on the basis of a showing of past torture. But “[i]n assessing whether it is more likely than not that an applicant would be tortured ..., all evidence relevant to the possibility of future torture shall be considered, including ... [e]vidence of past torture inflicted upon the applicant.” 8 C.F.R. § 1208.16(c)(3).
B. Standard of Review
We review the BIA’s legal determinations de novo, and its findings of fact under a substantial-evidence standard.
Elzour v. Ashcroft,
Moreover, the BIA’s interpretations of ambiguous provisions in the INA are entitled to particular respect under
Chevron U.S.A., Inc. v. Natural Res. Def. Council, Inc.,
Finally, we must be cautious not to assume the role of the BIA. Decisions should be made in the first instance by the BIA. And when it has failed to address a ground raised by an applicant in support of her claim, we should ordinarily not reverse on that ground but should instead remand if the ground appears to have any substance.
See INS v. Orlando Ventura,
C. Application to FGM
As acknowledged by the BIA in its decision in this case, FGM can be the basis of a claim of past persecution. An alien making such a claim must establish that (1) the FGM constituted persecution; (2) the alien belonged to a particular social group; and (3) there was a nexus between the FGM and membership in the group— that is, the FGM was performed on account of her membership in that group. We proceed to examine each of .the components of such a claim.
1. Persecution
The INA does not define
persecution.
We have held that persecution “requires the infliction of suffering or harm ... in a way regarded as offensive,”
Woldemeskel v. INS,
[T]he FGM practiced by her tribe ... is an extreme type involving cutting the genitalia with knives, extensive bleeding, and a 40-day recovery period.
FGM is extremely painful and at least temporarily incapacitating. It permanently disfigures the female genitalia. FGM exposes the girl or woman to the risk of serious, potentially life-threatening complications. These include, among others, bleeding, infection, urine retention, stress, shock, psychological trauma, and damage to the urethra and anus. It can result in permanent loss of genital sensation and can adversely affect sexual and erotic functions.
Id.
at 361,
Although many cases construing
persecution
involve persecutors who had the subjective intent to punish their victims, “this subjective punitive or malignant intent is not required for harm to constitute persecution.”
Id.
at 365,
Other circuits agree that FGM constitutes persecution, whether for the purpose of determining past persecution or the purpose of determining well-founded fear of persecution.
See Mohammed v. Gonzales,
2. Social Group
Although Ms. Niang has added various factual embellishments, her central claim has been that she was subjected to FGM because she was a female within a tribe practicing this ritual. Even if her embellishments are disbelieved, she may be entitled to relief if females in the Tukulor Fulani tribe constitute a social group within the meaning of the INA and she suffered FGM because she is a female in that group.
This circuit has not yet addressed the meaning of “membership in a particular social group.” 8 U.S.C. § 1101(a)(42)(A). But the BIA did so in In re Acosta, 19 I. & N. Dec. 211, 233-234 (1985), overruled on other grounds by In re Mogharrabi, 19 I. & N. Dec. 439 (1987). Acosta began its analysis by noting the ambiguity of the statutory term:
Congress did not indicate what it understood [membership in a particular social group] to mean, nor is its meaning clear in the [Refugee] Protocol. This ground was not included in the definition of a refugee proposed by the committee that drafted the U.N. Convention; rather it was added as an afterthought. International jurisprudence interpreting this ground of persecution is sparse. It has been suggested that the notion of a ‘social group’ was considered to be of broader application than the combined notions of racial, ethnic, and religious groups and that in order to stop a possible gap in the coverage of the U.N. Convention, this ground was added to the definition of a refugee. A purely linguistic analysis of this ground of persecution suggests that it may encompass persecution seeking to punish either people in a certain relation, or having a certain degree of similarity, to one another or people of like class or kindred interests, such as shared ethnic, cultural, or linguistic origins, education, family background, or perhaps economic activity. The [United Nations High Commissioner for Refugees] has suggested that a ‘particular social group’ connotes persons of similar background, habits, or social status and that a claim to fear persecution on this ground may frequently overlap with persecution on other grounds such as race, religion, or nationality.
Id.
at 232-33,
Applying the canon of construction
ejus-dem generis, see Black’s Law Dictionary
535 (7th ed.1999) (defining
ejusdem gener-is
as “[a] canon of construction that when a general word or phrase follows a list of specific ... things, the general word or phrase will be interpreted to include only ... things of the same type as those listed.”), the BIA construed
membership in a particular social group
in a manner consistent with the more specific grounds listed. Because
race, religion, nationality,
and
political opinion
“describe[ ] persecution aimed at an immutable characteristic: a characteristic that either is beyond the power of an individual to change or is so fundamental to individual identity or conscience that it ought not be required to be changed,” the BIA reasoned that the characteristics defining a particular social
*1199
group must also be so limited. 19 I.
&
N. Dec. at 233,
[W]e interpret the phrase ‘persecution on account of membership in a particular social group’ to mean persecution that is directed toward an individual who is a member of a group of persons all of whom share a common, immutable characteristic. The shared characteristic might be an innate one such as sex, color, or kinship ties, or in some circumstances it might be a shared past experience such as former military leadership or land ownership.... [W]hatever the common characteristic that defines the group, it must be one that the members of the group either cannot change, or should not be required to change because it is fundamental to their individual identities or consciences.
Id.
at 233,
As we have previously stated, we must defer to the BIA’s permissible interpretation of ambiguous language in the INA.
See INS v. Aguirre-Aguirre,
We recognize that two circuits may take a different view. But the leading case in one does not even cite
Acosta,
much less explain why the court should not defer to the BIA’s definition of
social group. See Gomez v. INS,
Applying the Acosta definition of social group, the female members of a tribe would be a social group. Both gender and tribal membership are immutable characteristics. Indeed, Acosta itself identified sex and kinship ties as characteristics that can define a social group. See Acosta, 19 I. & N. Dec. at 233.
There may be understandable concern in using gender as a group-defining characteristic. One may be reluctant to permit, for example, half a nation’s residents to obtain asylum on the ground that women are persecuted there.
See Safaie,
We are not persuaded that the BIA, contrary to the language of Acosta, requires more than gender plus tribal membership to identify a social group. The one decision that may suggest this requirement is Kasinga, in which the BIA granted asylum to a woman who feared being subjected to FGM if returned to her native land. The BIA described her social group as “young women of the Tchamba-Kunsuntu Tribe who have not had FGM, as practiced by that tribe, and who oppose the practice.” 21 I. & N. Dec. at 365. The Board noted that its description was “very similar to the formulations suggested by the parties.” Id. Sec id. at 372 (Filppu, Bd.Mem., concurring) (“the social group definition has not been a real source of dispute between the parties”). It explained its ruling as follows:
The defined social group meets the test we set forth in Matter of Acosta [, 19 I. & N. Dec.] at 233,1985 WL 56042 . See also Matter of H-, Interim Decision 3276 (BIA 1996) (finding that identifiable shared ties of kinship warrant characterization as a social group). It also is consistent with the law of the United States Court of Appeals for the Third Circuit, where this ease arose. Fatin v. INS,12 F.3d 1233 , 1241 (3d Cir.1993) (stating that Iranian women who refuse to conform to the Iranian Government’s gender-specific laws and social norms may well satisfy the Acosta definition).
In accordance with Acosta, the particular social group is defined by common characteristics that members of the group either cannot change, or should not be required to change because such characteristics are fundamental to their individual identities. The characteristics of being a “young woman” and a “member of the Tchamba-Runsuntu Tribe” cannot be changed. The characteristic of having intact genitalia is one that is so fundamental to the individual identity of a young woman that she should not be required to change it.
Id.
at 365-66,
3. Nexus
For persecution to be “on account of’ membership in a social group, the victim’s protected characteristic must be central to the persecutor’s decision to act against the victim.
See Gebremichael v. INS,
We believe that opposition is not required in order to meet the “on account of’ prong in female genital mutilation cases. The persecution at issue in these cases — the forcible, painful cutting of a female’s body parts — is not a result of a woman’s opposition to the practice but rather a result of her sex and her clan membership and/or nationality. That is, the shared characteristic that motivates the persecution is not opposition, but the fact that the victims are female in a culture that mutilates the genitalia of its females.
Mohammed v. Gonzales,
D. Ms. Niang’s Claims
1. Asylum and Restriction on Removal
As previously explained, if Ms. Niang can establish that she has suffered persecution on account of her membership in a social group, she may be a refugee eligible for asylum and she may be presumptively entitled to a restriction on removal. The IJ, affirmed by the BIA, rejected her claim of past persecution, however, because he found incredible her account of how she suffered FGM. We will not set aside such a credibility determination if the “IJ ... give[s] specific, cogent reasons for an adverse credibility finding” that are not “based on speculation or conjecture.”
Wiransane,
But Ms. Niang’s claim of past persecution does not depend entirely on her account of the attack by her family. She has made the broader claim that she suffered FGM on account of her being a female member of the Tukulor Fulani tribe. It is undisputed that she suffered FGM, and the injuries described by Dr. Wilson — her scarring, inability to engage in normal sexual relations, and inability to bear children naturally' — would certainly be sufficiently serious to qualify her FGM as persecution. It is also undisputed that she is a female Tukulor Fulani, and the IJ did not appear to question that the custom of the tribe is to perform FGM on its female members. The State Department Report on Female Genital Mutilation reports that about 20% of Senegalese women have undergone the mutilation and lists the “Toucouleur” tribe as one of the specific ethnic groups that practice the ritual. R. at 326. The IJ apparently believed Ms. Niang’s statements that all her sisters had undergone the genital mutilation at a younger age, because he used that information to discredit her testimony that her family performed the FGM when she was 25.
Yet neither the IJ nor the BIA addressed this broader claim. We therefore must remand for further proceedings to resolve it. If the BIA determines that she did suffer persecution in the form of FGM as the result of her tribal membership, it would next need to address whether the persecution was “committed by the government or forces the government is
*1202
either unable or unwilling to control.”
Berishaj,
2. Convention Against Torture
In contrast to the presumptions applicable in asylum and restriction-on-removal proceedings, under the CAT a petitioner is not entitled to a presumption of future torture based on evidence of past torture; nor does a showing of past torture automatically render her CAT eligible. Although past torture is a relevant consideration for the IJ in assessing the likelihood of future torture, 8 C.F.R. § 1208.16(c)(3)(i), it is only one factor in the assessment. Here, our review of Ms. Niang’s CAT claim is controlled by the permissible finding that she is untruthful.
See Wiransane,
III. CONCLUSION
We AFFIRM the denial of relief under the CAT, REVERSE the decision of the BIA with respect to asylum and restriction on removal, and REMAND this case for further proceedings consistent with this opinion.
Notes
. On March 1, 2003 the INS ceased to exist, and its responsibilities were divided among three distinct agencies formed within the new Department of Homeland Security. See Homeland Security Act of 2002, Pub.L. No. 107-296, §§ 441, 451, 116 Stat. 2135 (November 25, 2002). But because the actions Ms. Niang challenges in this appeal were taken prior to this reorganization, we will refer to the relevant government agency as the INS.

The Convention Against Torture is formally referred to as The United Nations Convention Against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment, Dec. 10, 1984, 1465 U.N.T.S. 85.
