Material Omissions, Implausible Repetition, and Missing Corroboration Sustain Adverse Credibility; Discrimination of Black Fulanis in Mauritania Does Not Establish a “Pattern or Practice” of Persecution

1. Introduction

In Amadou Sy v. Pamela Bondi, the Sixth Circuit reviewed a final order of removal after the Board of Immigration Appeals (“BIA”) dismissed Amadou Sy’s appeal from an immigration judge (“IJ”). Sy, a Mauritanian national who entered the United States unlawfully, sought asylum, withholding of removal, and Convention Against Torture (“CAT”) protection, asserting he would be killed or tortured in Mauritania due to his ethnicity (Fulani) and political protest activity.

The central issues were (1) whether substantial evidence supported the agency’s adverse credibility determination, and (2) whether the record compelled a finding of a “pattern or practice” of persecution of black Fulanis in Mauritania.

2. Summary of the Opinion

The Sixth Circuit denied the petition for review. It held that substantial evidence supported the BIA’s affirmance of the IJ’s adverse credibility finding, based on material omissions and inconsistencies (notably the late-appearing claim that Sy’s brothers were also arrested), the implausibly repetitive account of four arrests over twelve years, an internally suspect passport narrative, and lack of readily available corroboration (family testimony/affidavits and medical records).

The court also upheld the BIA’s determination that Sy failed to show a pattern or practice of persecution of black Fulanis in Mauritania, explaining that the evidence showed discrimination and marginalization, not the “extreme concept” of persecution.

3. Analysis

A. Precedents Cited

  • Kilic v. Barr, 965 F.3d 469 (6th Cir. 2020)
    • Role in Sy: Supplied the review framework: when the BIA issues a written opinion, the court reviews the BIA as the final decision, and also reviews the IJ’s reasoning to the extent the BIA adopted it. It also reaffirmed the standards of review: de novo for legal issues; substantial evidence for factual findings including credibility.
  • Nasrallah v. Barr, 590 U.S. 573 (2020)
    • Role in Sy: Provided the “substantial evidence” formulation—agency findings stand unless “any reasonable adjudicator would be compelled to disagree.” The court repeatedly invoked this high bar to reject Sy’s efforts to relitigate credibility and country-conditions determinations.
  • Hachem v. Holder, 656 F.3d 430 (6th Cir. 2011)
    • Role in Sy: Anchored the “totality of the circumstances” approach to credibility, which the opinion then tied to the statutory credibility factors in 8 U.S.C. § 1158(b)(1)(B)(iii).
  • Slyusar v. Holder, 740 F.3d 1068 (6th Cir. 2014)
    • Role in Sy: Provided the decisive doctrinal consequence: an adverse credibility finding is “fatal” to asylum, withholding, and CAT claims, permitting the agency to deny relief without reaching the merits of an unbelievable narrative.
  • Kolov v. Garland, 78 F.4th 911 (6th Cir. 2023), abrogated on other grounds by, Riley v. Bondi, 606 U.S. 259 (2025)
    • Role in Sy: Supported the proposition that a material omission can indicate lack of credibility. The court used it to characterize Sy’s failure to mention his brothers’ alleged persecution in his written application—despite a prompt asking about whether he “or [his] family members” had been persecuted—as a significant credibility problem.
    • Note on “abrogated on other grounds”: The citation signals that the specific credibility-omission point relied on here remains usable, while some other, unrelated holding in Kolov v. Garland was displaced by Riley v. Bondi.
  • Tandia v. Gonzales, 487 F.3d 1048 (7th Cir. 2007)
    • Role in Sy: Sy invoked this out-of-circuit case to argue that obtaining a passport should not undermine credibility. The Sixth Circuit distinguished it: Tandia v. Gonzales addressed speculation about official approval where bribery was involved, whereas Sy claimed he bought a passport from the same police allegedly trying to kill him and then exited through government controls—facts the court deemed rationally implausible and internally inconsistent.
  • Ali v. Ashcroft, 366 F.3d 407 (6th Cir. 2004)
    • Role in Sy: Framed “persecution” as an “extreme concept” and explained the pattern-or-practice inquiry focuses on what happens to “others who are similarly situated.” The court used Ali v. Ashcroft to reject Sy’s attempt to bootstrap his own discredited account into a generalized pattern claim.
  • Mikhailevitch v. I.N.S., 146 F.3d 384 (6th Cir. 1998)
    • Role in Sy: Supplied the definitional line between discrimination and persecution—persecution requires “punishment or the infliction of suffering or harm.” This became the court’s key tool for evaluating Sy’s expert’s description of marginalization and economic constraint as insufficient to establish persecution.

B. Legal Reasoning

1) Credibility: omissions + inconsistency + implausibility + missing corroboration

The court treated the credibility determination as the linchpin. Applying the statutory credibility factors (8 U.S.C. § 1158(b)(1)(B)(iii)) and Hachem v. Holder, the court held the agency permissibly relied on:

  • Material omission about family persecution: Sy’s written application and declaration did not mention that his brothers were arrested and beaten with him—even though the form asked about whether he “or [his] family members” had been persecuted—yet his testimony later made his brothers central participants in multiple arrests. The court treated this as a meaningful credibility defect under the logic reflected in Kolov v. Garland.
  • Failure to reconcile the omission with sworn “complete” application: Sy’s attempted explanation (“my lawyer probably didn’t write it”) clashed with his sworn statement that the application was “truthful, accurate, and complete.” The court found the agency could reasonably view that as irreconcilable.
  • Inherent implausibility via repetitive narrative: The account of four arrests—each involving arrest after protests, exactly five days’ detention, stripping, beating, being left for dead, and hospital transport by a passerby—was deemed rationally suspicious in its sameness across a 12-year span, plus an added inconsistency about a 2023 “escape” versus the prior sworn statement that police “let [him] go” each time.
  • Passport narrative undermining fear-and-flight logic: The agency could doubt that a wanted dissident would obtain a passport from the police allegedly trying to kill him and still have the government stamp and permit departure. The Sixth Circuit characterized that doubt as a permissible common-sense inference, not speculation.
  • Corroboration failures (8 U.S.C. § 1158(b)(1)(B)(ii)): The absence of an affidavit or testimony from the brother allegedly living in New York—and the lack of medical records despite multiple claimed near-death hospital visits—supported the agency’s conclusion that Sy “failed to corroborate his case.”
  • Transit-country conduct: While not framed as a dispositive legal bar, the court found it rationally damaging that Sy did not seek asylum in multiple countries en route if his primary goal was safety.

With those factors, the court held substantial evidence supported the adverse credibility finding. Under Slyusar v. Holder, that credibility failure was “fatal” to asylum, withholding, and CAT claims.

2) Pattern-or-practice: discrimination and marginalization are not “persecution”

The court nevertheless addressed the alternative pattern-or-practice claim and held substantial evidence supported the BIA’s no-pattern finding. Relying on Ali v. Ashcroft and Mikhailevitch v. I.N.S., it emphasized:

  • Persecution requires severe harm, not merely offensive treatment, discrimination, lack of education, or constrained economic opportunity.
  • The expert testimony describing an “uneducated and marginalized” underclass performing manual labor described discrimination and structural inequality, not the “punishment” or “infliction of suffering or harm” required for persecution.
  • A pattern-or-practice case must be grounded in evidence of harm to similarly situated others, not a repackaging of an applicant’s own discredited story.

C. Impact

  • Credibility practice in the Sixth Circuit: The opinion reinforces that IJs and the BIA may rely on (i) material omissions (especially where forms expressly ask about family persecution), (ii) highly repetitive, “too-similar” narratives as implausible, and (iii) readily available corroboration (family in the United States, medical records) when testimony is not persuasive on its own.
  • Passport evidence: While distinguishing Tandia v. Gonzales, the decision signals that passport acquisition can materially undercut credibility where the applicant’s own account ties the passport to the alleged persecutor and contradicts the asserted level of governmental hostility.
  • Pattern-or-practice claims: The opinion confirms a stringent line between discrimination and persecution; socio-economic marginalization, without evidence of severe harm meeting the Sixth Circuit’s persecution definition, will be insufficient to establish a pattern-or-practice theory.
  • Case selection and record-building: For future petitioners (including Mauritania-based claims), the decision underscores the litigation risk of leaving out key family-persecution facts from initial filings and the importance of collecting corroboration early (affidavits, medical documentation, accessible witnesses).

4. Complex Concepts Simplified

  • Asylum vs. withholding vs. CAT:
    • Asylum is discretionary protection requiring a qualifying fear of persecution on protected grounds.
    • Withholding of removal is mandatory if a higher likelihood standard is met (but the opinion resolves the case on credibility).
    • CAT protection turns on likely torture with government involvement or acquiescence; again, credibility can be dispositive when the torture narrative is not believed.
  • Adverse credibility determination: A finding that the applicant’s story is not reliable. Under Slyusar v. Holder, it can end the case because the agency need not accept the factual basis for persecution or torture.
  • Substantial evidence review: A highly deferential standard. The court does not ask whether it would have decided differently, but whether the record compels a different result (as framed by Nasrallah v. Barr).
  • Corroboration (8 U.S.C. § 1158(b)(1)(B)(ii)): Even if testimony is offered, the agency may require supporting evidence when it is reasonably obtainable—such as statements from family members with firsthand knowledge or medical records.
  • Pattern or practice of persecution: A claim that a group faces systematic persecution such that an individual member faces risk upon return even without being personally targeted. The Sixth Circuit stressed it must be persecution (severe harm), not discrimination.
  • Persecution vs. discrimination: Under Mikhailevitch v. I.N.S., persecution involves severe harm—“punishment” or “infliction of suffering.” Discrimination and marginalization, while serious, may fall short legally.

5. Conclusion

Sy v. Bondi consolidates two core Sixth Circuit themes in asylum adjudication: (1) credibility can be defeated by material omissions, internal inconsistencies, implausibly repetitive accounts, and the absence of readily available corroboration—making the adverse credibility finding dispositive under Slyusar v. Holder; and (2) for pattern-or-practice theories, evidence of discrimination and socio-economic marginalization does not meet the circuit’s demanding definition of persecution under Mikhailevitch v. I.N.S. and Ali v. Ashcroft. The decision’s practical significance lies in its record-building message: accurate initial applications and corroboration from accessible sources are often decisive.
