Andres Amaya-Artunduaga (Amaya) petitions for review of the Board of Immigration Appeals’ (BIA) order adopting and affirming an Immigration Judge’s (IJ’s) decision finding him ineligible for asylum and denying his application for withholding of removal under the Immigration and Nationality Act (INA), 8 U.S.C. §§ 1158, 1231, as amended by the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (IIRIRA), Pub.L. No. 104-208, 110 Stat. 3009 (1996) (amended by the REAL ID Act of 2005, Pub.L. No. 109-13, 119 Stat. 302 (2005)). 1 After review, we dismiss the petition.
I. BACKGROUND
Amaya, a native and citizen of Colombia, arrived in the United States on or about March 28, 2002. On February 18, 2003, the Department of Homeland Security sent Amaya a Notice to Appear, charging him with removability under 8 U.S.C. § 1182(a)(6)(A)® as an alien present in the United States without having been admitted or paroled. Conceding he was removable as charged, Amaya sought relief under the INA, asserting he was eligible for asylum and withholding of removal based on his past persecution and well-founded fear of future persecution by the Revolu *1249 tionary Armed Forces of Colombia (FARC) on account of his political opinion. 2
In his asylum application, Amaya referenced several events in 2001 and 2002. He explained, for example, that after attending a political demonstration in support of Alvaro Uribe-Vélez in October 2001, members of the FARC pulled his vehicle to the side of the road and warned him, along with his uncle and two others, against any political activity under pain of death. Further, Amaya claimed that in December 2001, after he filmed a political meeting and distributed political literature, the FARC sent him a note describing Amaya and his family as military targets. Finally, Amaya stated that in February 2002, while campaigning for Uribe-Velez, he was abducted by members of the FARC. He noted the FARC forced him and other abductees to walk several hours in the mountains, during which they beat him and assassinated a sick woman. Soon thereafter, Amaya moved to Bogotá and Cali, but fled because of threatening phone calls from the FARC.
At his hearing, Amaya recounted these events. For the first time, however, he stated that during the October 2001 incident, members of the FARC not only threatened him, but subjected him to physical abuse. Similarly, Amaya testified at the hearing that his February 2002 abduction lasted three weeks, not a few days. When asked about these inconsistencies, Amaya was unable to proffer an explanation. Citing these and several other incongruities and implausibilities, the IJ expressly found Amaya incredible, and denied his claims for asylum and withholding of removal.
The BIA dismissed Amaya’s appeal, finding the IJ’s decision evinced no clear error. While specifically declining to adopt those portions of the IJ’s opinion based on conjecture, speculation, and personal belief, the BIA held that significant inconsistencies in Amaya’s narrative, especially those regarding the October 2001 and February 2002 incidents, supported the IJ’s adverse credibility determination. Amaya then petitioned this Court for review, asserting (1) the IJ erred in finding him incredible; (2) the IJ’s bias against him rendered the proceedings fundamentally unfair; and (3) the IJ failed to make a finding regarding past persecution in relation to his claim for withholding of removal. 3
II. DISCUSSION
A. Adverse Credibility Determination
In his petition, Amaya first challenges the IJ’s and BIA’s adverse credibility determinations, primarily arguing the IJ abused his discretion by (1) requiring corroborating evidence to substantiate Ama-ya’s story; (2) basing the adverse credibility determination on speculation and conjecture; and (3) basing the adverse credibility determination on minor dis *1250 crepancies and typographical problems. The Government, in turn, asserts because Amaya failed to challenge the adverse credibility determination before the BIA, we lack jurisdiction over Amaya’s claim. In the alternative, the Government argues the IJ’s and BIA’s credibility findings are supported by substantial evidence.
We review our subject matter jurisdiction de novo.
See Gonzalez-Oropeza v. U.S. Att’y Gen.,
In the instant case, Amaya failed to challenge the IJ’s adverse credibility determination in both his notice of appeal and brief before the BIA. The BIA, however, addressed the IJ’s adverse credibility determination
sua sponte.
This leaves open the question of whether we have jurisdiction over a claim when an alien, without excuse or exception, fails to exhaust that claim, but the BIA nonetheless considers the underlying issue
sua sponte.
We have no clear guidance on this narrow issue from our sister circuits.
See Naza-rova v. INS,
Nonetheless, circuit precedent clearly states that, absent a cognizable excuse or exception, “we lack jurisdiction to consider claims that have not been raised before the BIA.”
Sundar,
That the BIA reviewed the IJ’s adverse credibility determination
sua sponte
does not alter our conclusion. Certainly, the exhaustion doctrine exists, in part, to avoid premature interference with administrative processes and to allow the agency to consider the relevant issues.
See, e.g., Sun v. Ashcroft,
B. Due Process Claim
Amaya next argues the proceedings before the IJ denied him due process of law. More specifically, Amaya asserts the IJ “color[ed] the hearing with his belief system” and treated Amaya with “heavy sarcasm and hostility,” such that the proceedings were fundamentally unfair. The Government, in turn, asserts we lack subject matter jurisdiction over Amaya’s due process claim because he failed to object to the IJ’s behavior in his filings before the BIA.
To reiterate, we review our subject matter jurisdiction de novo. See
Gonzalez-Oropeza,
Amaya’s allegation of a due process violation — that he was denied a full and fair hearing before a neutral factfinder — is precisely the kind of procedural error which requires exhaustion.
See, e.g., Abdulrahman v. Ashcroft,
III. CONCLUSION
For the foregoing reasons, we dismiss Amaya’s petition for review.
PETITION DISMISSED.
Notes
. Because Amaya's removal and asylum proceedings commenced after April 1, 1997, the permanent provisions of IIRIRA govern his petition for review.
. Amaya also sought relief under the United Nations Convention Against Torture and Other Cruel, Inhuman, or Degrading Treatment or Punishment (CAT), 8 C.F.R. § 208.16(c). Because he does not appeal the denial of CAT relief, we need not discuss this claim.
. Amaya's third claim — that the IJ was obligated to make a finding regarding past persecution with respect to his claim for withholding of removal — is without merit. The IJ denied Amaya asylum relief, and it is axiomatic that where an applicant fails to meet the burden for asylum, he necessarily cannot meet the more stringent burden for withholding of removal.
