Judge WALLACE concurs only in the Background and Part II of the Discussion, and in the result.
Petitioners Jose Godofredo Ucelo-Go-mez and Ana Mariela Espana-Espinosa (husband and wife) are natives and citizens of Guatemala, who challenge a decision by the Board of Immigration Appeals (“BIA”) that summarily affirmed the oral decision *182 of an immigration judge (“U”) that (1) denied their applications for asylum and withholding of removal under the Immigration and Naturalization Act (“INA”) and their applications for protection under the Convention Against Torture (“CAT”), and (2) directed their removal to Guatemala. Their asylum claim is based on membership in a social group composed of affluent Guatemalans, who suffer persecution fueled by class rivalry in an impoverished society.
The BIA summarily affirmed the IJ’s determination that affluent Guatemalans do not constitute a social group for purposes of asylum. Because the affirmance was summary, there is no agency determination on the protectibility of that particular group.
See Shi Liang Lin v. DOJ,
BACKGROUND
Mr. Ucelo-Gomez and Ms. Espana-Es-pinosa married in February 1996, and entered the United States in August 2001 using forged travel visas and false names. The couple subsequently pled guilty to attempted illegal entry with counterfeit documents and each paid a $3,000 fine. Petitioners have conceded their removability.
In them airport statements: (1) Ucelo-Gomez said that he left Guatemala to “look for work”; (2) Espana-Espinosa said that she left Guatemala “to visit [her] uncle in Los Angeles, California”; and (3) both said they had no “fear or concern about being returned to [Guatemala] or being removed from the United States” and would not be harmed if returned to Guatemala.
Taking a different tack in her petition, Espana-Espinosa states that her sister was kidnapped by an “organized political gang[ ]” in December 1996, shot in the leg, and released in January 1997; that the captors threatened petitioners, causing them “to continually change [their] location” and to seek refuge in the United States; and that she fears that on return she would be “harassed and threatened” or “kidnapped, physically harmed, even killed” because of “class hatred” harbored by the same political gangs that abducted her sister. 1
At the January 2, 2003 hearing before the IJ, petitioners (through counsel) premised their asylum claim on persecution by reason of membership in a particular social group composed of “higher socio-economic” Guatemalans. Specifically, Espana-Espinosa testified as follows:
• She came from a well-off family; she and her husband had a good life in Guatemala; they own a house that is presently rented out; the couple employed a housekeeper; and she attended college and obtained a teacher’s degree.
• In December 1996, the couple received anonymous phone calls demanding ransom for the release of Espana-Espinosa’s sister, and threatening *183 that, unless the ransom was paid, they would face the same fate.
• By reason of telephonic and written threats, petitioners moved (in October 1998) to another town in Guatemala but the threats resumed several months later, forcing them to move once more.
• After their final relocation, petitioners were unemployed and subsisted off savings and investment income.
• Espana-Espinosa twice reported the threats to the police, to no apparent effect.
• The couple never paid her sister’s ransom, but the sister was released by her captors after they “saw her wounded in her leg.”
Espana-Espinosa conceded on cross-examination that her airport statement denied any fear about returning to Guatemala, and asserted that the denial was untruthful and was made only because she feared that otherwise she would be jailed in the United States. She also acknowledged that her wealthy uncle in Guatemala (not so rich as herself) has never been threatened.
Ueelo-Gomez’s testimony at the hearing corroborated much of his wife’s story, adding that he drew income from a discotheque and a carpentry workshop that employed two people, and that he could likely have supported his family on his income had they remained in Guatemala. Ucelo-Gomez testified that the couple came to the United States for non-economic reasons, but conceded on cross-examination that his father was also “rich,” and that none of his relatives (including his father) had ever been threatened for any reason.
In an oral decision, the IJ denied petitioners’ applications on the ground that they failed to establish past persecution under 8 C.F.R. § 208.13(b)(1). The IJ ruled that receiving a ransom demand from unknown persons does not constitute persecution, and that petitioners had proffered no evidence that these threats resulted, or would have resulted, in any harm. Alternatively, the IJ concluded that, even if petitioners had suffered persecution, it was not on account of their race, religion, nationality, membership in a particular social group, or political opinion. The IJ held that a group made up of affluent Guatemalans was not a “readily-identifiable social group” and was “too broad to define a social group for purposes of asylum.” He concluded that the characteristics of that “group” are not immutable, and there was insufficient evidence that similarly-situated Guatemalans would be identified by would-be persecutors.
The IJ also found petitioners’ stories not credible, citing inconsistencies between their airport statements and their testimony at the asylum hearing. In addition, the IJ found that petitioners failed to establish a well-founded fear of future persecution under 8 C.F.R. § 208.13(b)(2), because nothing in the admitted background materials or country reports indicated that wealthy Guatemalans “are specifically targeted for persecution.” Because petitioners failed to demonstrate the requisite well-founded fear, the IJ ruled that they failed to meet the clear probability standard required for withholding of removal under § 241(b)(3) of the INA. Finally, the IJ concluded that their CAT claim was baseless because they had no fear of any actions against them by the government of Guatemala. Accordingly, the IJ ordered petitioners removed to Guatemala.
The BIA affirmed without opinion.
*184 DISCUSSION 2
I
When the BIA affirms without opinion, we review the IJ’s decision as the final agency determination.
See Twum v. INS,
We typically afford “particular deference” to an IJ’s credibility finding, “mindful that the law must entrust some official with responsibility to hear an applicant’s asylum claim, and the IJ has the unique advantage among all officials involved in the process of having heard directly from the applicant.”
Zhou Yun Zhang,
Here, the adverse credibility finding is arguably infirm and, in any event, of limited influence and effect in the context of this petition. First, the IJ failed to consider Espana-Espinosa’s testimony that the kidnappers threatened petitioners with being kidnapped themselves if they failed (as they did) to pay the ransom, and that their complaints to the police were unavailing. Second, the IJ cited differences between the petitioners’ airport statements and their testimony, but did not evaluate Espana-Espinosa’s explanation that she feared being jailed in the United States if she expressed any fear about being returned to Guatemala. These omissions might themselves support a remand,
see Cao He Lin,
II
Does a given group of persons qualify as a “particular social group,” such that that group of persons is protected under the INA? Here, petitioners assert that they fear persecution in them native Guatemala because of their membership in a group composed of affluent Guatemalans, a group that the BIA has never recognized; the BIA’s summary affirmance provides this *185 Court no categorical guidance on that point. The question presented on this appeal is whether we may determine — absent an explicit, non-summary ruling by the BIA in the first instance — ’that this group of persons is a “particular social group” protectible under the INA.
A
BIA interpretations are accorded
Chevron
deference “when it appears that Congress delegated authority to the agency generally to make rules carrying the force of law,
and
that the agency interpretation claiming deference was promulgated in the exercise of that authority.”
United States v. Mead Corp.,
In Shi Liang Lin v. DOJ, we declined to accord Chevron deference to “any statutory construction of the INA set forth in a summarily affirmed IJ opinion.” Id. at 191. There, we withheld Chevron deference from a one-line disposition by the BIA because (1) in such a summary affir-mance, the BIA has laid down no “rule” carrying the force of law and promulgated in the exercise of the Attorney General’s authority, and (2) the IJ would be improperly delegated rule-making authority delegated only to the BIA. Id. at 189-90. “[W]ere we to accord Chevron deference to non-binding IJ statutory interpretations, we could find ourselves in the impossible position of having to uphold as reasonable on Tuesday one construction that is completely antithetical to another construction we had affirmed as reasonable the Monday before.” Id. at 190. Accordingly, we remanded that petition to the BIA.
Our reasoning in
Shi Liang Lin
anticipated the Supreme Court’s very recent opinion in
Gonzales v. Thomas,
— U.S. -,
*186
The Supreme- Court reversed the Ninth Circuit in a unanimous
per curiam
opinion. The Court held that the appellate court had usurped the BIA’s administrative role by making “the basic asylum eligibility decisions.”
Thomas,
Thomas
relies on an elementary precept of administrative law: “judicial judgment cannot be made to do service for an administrative judgment.”
SEC v. Chenery Corp.,
The agency can bring its expertise to bear upon the matter; it can evaluate the evidence; it can make an initial determination; and, in doing so, it can, through informed discussion and analysis, help a court later determine whether its decision exceeds the leeway that the law provides.
Thomas,
Furthermore, the agency interpretation required by
Thomas
and
Ventura
is “in the first instance” a particularized interpretation by
the BIA.
Interpretations by individual IJs are insufficient to constitute the agency’s interpretations; the procedural posture of the Supreme Court’s opinion in
Ventura
(on which
Thomas
heavily relies) makes this clear. In Ventura, the Court remanded the question of changed country conditions in Guatemala to the BIA
even though the individual IJ had considered and decided the issue. See
Moreover, while the instant case (unlike Ventura) involves a summary affirmance, it is well-settled (as discussed above,
see ante
[11-12]) that the BIA’s summary af-firmance of an IJ’s decision does
not
constitute an official agency interpretation.
See Shi Liang Lin,
The BIA has not decided whether affluent Guatemalans constitute a “particular social group” within the meaning of the INA. Nor has the BIA decided the scope of the statutory term in a fact context so closely analogous to those presented here that we can rule now with assured confidence that petitioners are or are not part of a particular social group. Because there is no “basic asylum eligibility decision[]” by the BIA, we must remand.
Thomas,
At the same time, if a reviewing court can state with assured confidence (absent agency guidance as to its protectability under the INA) that a group would or would not under any reasonable scenario qualify as a “particular social group,” it need not remand, and may rule on the issue in the first instance. This option is not available in this case because the U made no factual finding as to petitioners’ wealth or status; so no case-specific determination is possible.
B
The result mandated in this case by
Thomas
is consistent with our remand to the BIA in
Shi Liang Lin v. DOJ,
Though our conclusion in Shi Liang Lin was driven by the BIA’s failure to “identify the specific statutory language pursuant to which it deemed spouses eligible for asylum under IIRIRA § 601(a), [or] ... to explain the reasoning motivating its chosen construction,” id. at 191, our reasoning was premised on our desire to review (and afford appropriate deference to) well-reasoned agency decisions, see id. Thus, whether or not the agency has articulated a coherent interpretation of a statutory term is of no moment where the agency’s opinion fails to provide a reviewing court sufficient direction.
To date, the BIA’s guidance as to what constitutes a “particular social group” has grown (essentially) out of its opinion in
Matter of Acosta,
Applying the doctrine of ejusdem gener-is, we 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 *188 should not be required to change because it is fundamental to their individual identities or consciences.
Id.
at 233 (emphasis supplied);
accord Gomez v. INS,
Our mandate serves the convenience of the BIA as well as this Court, and promotes the purposes of the INA. Thomas requires that we (in effect) certify this question. There is a press of cases raising similar questions in this Court, in the BIA, and before immigration judges; and the common project of deciding asylum cases promptly will be advanced by prompt guidance. We assume that in light of Thomas, the BIA will discharge its singular responsibility to expand upon Acosta, and to recognize and define social groups with particularity and to reject proposed groups (on an active and ongoing basis in the first instance) in order to avoid the ping-pong effect of a summary affirmance followed by a remand — a pattern that serves no one and squanders judicial resources. The BIA’s prompt consideration and decision is therefore essential. Accordingly, we impose a time limit for the BIA’s decision of the question posed on remand.
CONCLUSION
For the foregoing reasons, we hereby grant the petition, vacate the BIA’s order, and remand to the BIA for further proceedings consistent with this opinion. The BIA is hereby directed to issue its responsive opinion within 49 days, and it is reminded that the Court has received no response to its similar request in Shi Liang Lin (mandate issued October 12, 2005).
Notes
. Espana-Espinosa also lists an affiliation with the Partido Avanzada Nacional party, but she nowhere indicates that there is any nexus between her political affiliation and her claim of persecution, and concedes that neither she nor her husband had any political involvement.
. Judge Wallace concurs in the Background section and Part II of the Discussion section of the Opinion, and in the result, but does not reach or decide (1) whether there is a sufficient showing of persecution or (2) issues that bear upon the adverse credibility determination.
