OPINION OF THE COURT
Teferi Gelaneh is challenging a ruling of an Immigration Judge (“IJ”), affirmed by the Board of Immigration Appeals (“BIA”), which directs Gelaneh’s removal. Gelaneh is now before us on appeal from a judgment of the United States District Court for the District of New Jersey, which dismissed, for lack of jurisdiction, his habeas corpus petition. For the reasons which follow, we convert the instant appeal from the District Court’s denial of Gelaneh’s habeas petition into a petition for review, but conclude his petition for review must be denied.
I
Gelaneh is a native of Ethiopia and a lawful permanent resident who is currently separated from his American citizen wife, and who has two citizen children. On May 27, 1998, Gelaneh was convicted in a Pennsylvania court (the Court of Common Pleas of Lehigh County) of possessing a controlled substance — namely, cocaine — with intent to deliver, in violation of Pa. Stat. Ann. § 780.113(a)(30), and was sentenced to five years’ probation. Five days later, on June 1, 1998, the Immigration and Nationalization Service (“INS”) arrested Gelaneh and instituted removal proceedings.1 He was charged with being subject to removal pursuant to INA § 237(a)(2)(A)(iii), 8 U.S.C. § 1227(a)(2)(A)(iii) (conviction of an aggravated felony), and INA § 237(a)(2)(B)(I), 8 U.S.C. § 1227(a)(2)(A)(iii) (conviction of a controlled substances offense). After nine days of detention, Gelaneh, on June 10, 1998, was released on bail on posting a bond of $7,000.2
On April 8, 1999, the IJ ruled that Gelaneh’s offense did not constitute a “particularly serious crime,” 8 U.S.C. § 1231(b)(3)(B)(ii), and that Gelaneh was thus eligible to apply for withholding of removal pursuant to § 1231(b)(3)(A). Section 1231(b)(3)(A) bars the Attorney General from “removing] an alien to a country if the Attorney General decides that the alien’s 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.” Section 1231(b)(3)(B), however, contains an exception authorizing removal if the alien is found by the Attorney General to have “been convicted by a final judgment of a particularly serious crime,” and who is thus “a danger to the community of the United States.” Gelaneh also applied for relief under Article 3 of the Convention Against Torture (“CAT”),3 eligibility for *884which does not depend on the gravity of the alien’s conviction. After hearing testimony, the IJ found that Gelaneh had not met his burden of proving that he would face persecution (the necessary predicate for § 1231(b)(A) relief) or torture (the necessary predicate for CAT relief) upon his return to Ethiopia. The IJ thus denied both claims for relief, and ordered that Gelaneh be removed to Ethiopia.
Gelaneh filed a timely appeal with the BIA, which affirmed the IJ’s result on April 18, 2003. In affirming the IJ’s ultimate determination, the BIA, however, rejected the IJ’s conclusion that Gelaneh’s drug conviction is not a “particularly serious crime.” Instead, the BIA found that, under Matter of Y-L- 23 I & N Dec. 270 (A.G.2002), Gelaneh’s drug conviction presumptively constituted a “particularly serious crime,” and thus rendered him ineligible for withholding of removal under § 1231(b)(3)(A). Regarding the CAT claim, the BIA agreed with the IJ that Gelaneh had not met his burden of estabhshing that it was more likely than not that he would be tortured were he returned to Ethiopia, see 8 C.F.R.- § 1208.17. The BIA thus dismissed Gelaneh’s appeal, thereby rendering final his deportation order.
On May 15, 2003, Gelaneh filed a petition for habeas corpus, pursuant to 28 U.S.C. § 2241, seeking review of the BIA’s decision, and on June 18, 2004, the District Court dismissed Gelaneh’s petition. The District Court found that Gelaneh, having been released from INS detention on bail at the time he filed his § 2241 habeas petition, could not satisfy the jurisdictional requirement of § 2241 that a petitioner be “in custody.”4 The District Court also found an alternate bar, which it characterized as jurisdictional, to Gelaneh’s petition, concluding that the petition raised challenges solely to the BIA’s factual or discretionary determinations, and that such challenges were not cognizable under § 2241.
This timely appeal followed.
II
The REAL ID Act, which became law on May 11, 2005, amended 8 U.S.C. § 1252 so that petitions for review filed with the court of appeals are the “sole and exclusive *885means for judicial review of’ most orders of removal, including the order of removal at issue here. See 8 U.S.C. § 1252(a)(5) (1999 & Supp.2005); Bonhometre v. Gonzales, 414 F.3d 442, 445 (3d Cir.2005). “In so doing, the Act expressly eliminated district courts’ habeas jurisdiction over removal orders.” Jordan v. Attorney General of the United States, 424 F.3d 320, 2005 WL 2334686, at *4 (3d Cir. Sept.26, 2005); see also Bonhometre, 414 F.3d at 445; Kamara v. Attorney General of the United States, 420 F.3d 202 (3d Cir.2005).
[1] Further, “[w]e have also acknowledged that Congress left no doubt that the REAL ID Act’s changes to § 1252(a)(2)(D) would be retroactive.” Jordan, 424 F.3d 320, 323. Consequently, “those habeas petitions that were pending before this Court on the effective date of the REAL ID Act are properly converted to petitions for review and retained by this Court.” See REAL ID Act § 106(c); Bonhometre, 414 F.3d at 446. In converting petitioner’s habeas petition into a petition for review, we vacate the District Court’s decision denying habeas relief, and address the merits of Gelaneh’s claims as if they had been raised in a petition for review before us in the first instance. See Jordan, 424 F.3d 320, 323; Bonhometre, 414 F.3d at 446-47; Kamara, 420 F.3d at 210. Necessarily, “[t]his approach ... obviates the question of whether [the petitioner] was ‘in custody’ for purposes of § 2241” and is therefore “a jurisdictional inquiry no longer relevant to our analysis here.” Jordan, 424 F.3d 320, 323.
Despite the conversion of this appeal from a habeas petition into a petition for review, our scope of review remains the same. See Bonhometre, 414 F.3d at 446; Kamara, 420 F.3d at 210. Thus, examining Gelaneh’s claims, “we are limited to pure questions of law, and to issues of application of law to fact, where the facts are undisputed and not the subject of challenge.” Kamara, 420 F.3d at 210 (internal citations and quotation marks omitted). While we review the BIA’s legal determinations de novo, we afford Chevron deference to the BIA’s reasonable interpretations of immigration regulations. Id.

Before the IJ and BIA, Gelaneh had sought two forms of relief — deferral of removal pursuant to the CAT, and withholding of removal pursuant to 8 U.S.C. § 1231(b)(3)(A). We conclude that the BIA properly applied the law to the facts of this case when it denied Gelaneh’s CAT claim. We also review Gelaneh’s § 1231(b)(3)(A) claim of withholding of removal, but believe this claim too fails because Gelaneh was not prejudiced by certain deficiencies in the BIA’s opinion.
A
In determining that Gelaneh was not eligible for relief under the CAT, the BIA stated the correct legal standard, which required Gelaneh to prove that it was more likely than not that he would be tortured were he returned to Ethiopia, see 8 C.F.R. § 1208.16(c)(4) (“If the immigration judge determines that the alien is more likely than not to be tortured in the country of removal, the alien is entitled to protection under the Convention Against Torture”). Moreover, we agree with the BIA’s application of this standard to the IJ’s finding that Gelaneh gave “incredible” testimony and failed to provide any supporting documents establishing his identity. When — as here — the lack of credibility goes to the heart of the alien’s claim that he will be more likely than not be tortured if returned to his home country, denial of eligibility for relief under the CAT is appropriate. Accordingly, the BIA’s deter-*886initiation that Gelaneh is ineligible for relief under the CAT is sustained.
B
Withholding of removal is not available to the alien who has been convicted of a “particularly serious crime,” § 1231 (b)(3)(B)(ii), a category that includes all aggravated felonies for which the alien was sentenced to imprisonment for five or more years, § 1231 (b)(3)(B)(iv), as well as those crimes that the Attorney General deems to be particularly serious “notwithstanding the length of sentence imposed,” id. The decision as to whether a crime is “particularly serious” is thus committed to the discretion of the Attorney General. See generally § 1231(b)(3)(B).
In Matter of Y-L-, 23 I & N Dec. 270 (AG 2002), the Attorney General exercised the discretion afforded him under § 1231(b)(3)(B) and ruled that “[aggravated felonies involving unlawful trafficking in controlled substances presumptively constitute ‘particularly serious crimes’ within the meaning of ... 8 U.S.C. § 1231(b)(3)(B) (2000).” Id. at 270. The presumption would be rebutted “only under the most extenuating circumstances that are both extraordinary and compelling.” Id. The Attorney General went on to enumerate six such circumstances: “(I) a very small quantity of controlled substance; (2) a very modest amount of money paid for the drugs in the offending transaction; (3) merely peripheral involvement by the alien in the criminal activity, transaction, or conspiracy; (4) the absence of any violence or threat of violence, implicit or otherwise, associated with the offense; (5) the absence of any organized crime or terrorist organization involvement, direct or indirect, in relation to the offending activity; and (6) the absence of any adverse or harmful effect of the activity or transaction on juveniles.” In re YL-, 23 I. & N. Dec. 276-77. The Attorney General then stated that only if all of these circumstances were present “would it be appropriate to consider whether other, more unusual circumstances (e.g., the prospective distribution was solely for social purposes, rather than for profit) might justify departure from the default interpretation that drug trafficking felonies are ‘particularly serious crimes.’ ” Id. at 277.
In the case at bar, the BIA in three sentences summarily reversed the IJ’s determination that Gelaneh’s offense was not a particularly serious crime:
It is undisputed that [Gelaneh] has been convicted of a drug trafficking crime. Subsequent to the Immigration Judge’s decision, the Attorney General has issued a decision finding that such crimes presumptively constitute “particularly serious crimes” within the meaning of section 241(b)(3)(B) of the Immigration and Nationality Act, 8 U.S.C. § 1231(b)(3)(B). Matter of Y-L- 23 I & N Dec. 270 (A.G.2002) overruling Matter of S-S-, 22 I & N Dec. 458 (BIA 1999). [Gelaneh] is therefore subject to a mandatory bar to a grant of withholding of removal because he has been convicted of a particularly serious crime. Section 241(b)(3)(B) of the Act; 8 C.F.R. § 1208.16(d)(2).
J.A. at 21. Thus, even though Y-L created a presumption, and not a per se rule, that drug trafficking offenses constitute “particularly serious crimes,” the BIA automatically concluded that Gelaneh’s offense fell within the presumption. However, to comply with due process when deciding whether a criminal alien has committed a “particularly serious” crime, the Board must make an individualized determination, “rather than blindly following a categorical rule, i.e., that all drug convictions qualify as ‘particularly serious crimes.’ ” Chong v. Quarantillo, 264 F.3d 378, 387 (3d Cir. *8872001) (quoting Abdulai v. Ashcroft, 239 F.3d 542, 549 (3d Cir.2001)).5 Therefore, where, as here, the petitioner challenges not the result of a discretionary determination but the process by which that determination is made, we are not barred from reviewing his claim.
To provide Gelaneh with an individualized determination, the BIA was required to determine whether the six potentially extenuating circumstances enumerated in Matter of Y-L existed in his case. There is no evidence that the BIA did so here. As described above, the BIA simply noted the presumption of seriousness, and then summarily applied the presumption to Gelaneh’s offense. To be sure, “[t]he Board is not required to write an exegesis on every contention, but only to show that it has reviewed the record and grasped the movant’s claims.” Sevoian v. Ashcroft, 290 F.3d 166, 178 (3d Cir.2002). Here, however, the Board did not demonstrate that it was even aware of exceptions to the presumption of seriousness announced in Y-L, let alone that it had determined that Gelaneh’s offense did not constitute such an exception. When the Board treats a rebuttable presumption as an irrebuttable per se rale, it fails to provide the individualized determination that due process requires.
But there can be “no due process violation in the absence of prejudice.” Wilson v. Ashcroft, 350 F.3d 377, 381 (3d Cir.2003). Thus, to prevail on this petition for review, Gelaneh must show that the BIA likely would have reached a different result had the BIA attempted to address the presumption in proper fashion. Gelaneh has, however, proffered nothing to suggest that ampler BIA inquiry would have led the BIA to conclude that the circumstances of Gelaneh’s crime would have satisfied the six Y-L factors. Gelaneh avers that he was found with 21 grams of cocaine when he was arrested; the police report stated that it was 41 grams. Either amount would appear to be too substantial to qualify as “a very small quantity” as is required under the first YL factor. See, e.g., U.S.S.G. § 2Dl.l(c) (specifying 10-16 months imprisonment for a defendant convicted of trafficking 25 grams or less of cocaine if that defendant, like Gelaneh, has no prior criminal history).6 Further, Gelaneh was apprehended in the course of buying drugs with marked bills given to him by a confidential informant. He later told the police that he had been involved in three prior drug sales. Thus, it would have been unlikely that the BIA would have concluded that Gelaneh’s involvement in the drag transactions was “merely peripheral” as is required under the third Y-L factor. In short, with respect to at least two of the six factors, it is highly improbable that more careful BIA scrutiny would have led the BIA to find Gelaneh’s position meritorious — and Gelaneh would have needed to prevail on all six factors in order merely to cross the threshold of eligibility for withholding of removal.
Finally, even if the BIA had ultimately concluded that Gelaneh’s crime was not “particularly serious,” it could have found Gelaneh eligible for withholding of relief *888only if it had disagreed with the IJ’s ruling that Gelaneh did not establish a “clear probability” of persecution in Ethiopia, INS v. Stevic, 467 U.S. 407, 413, 104 S.Ct. 2489, 81 L.Ed.2d 321 (1984). Gelaneh presented the same evidence to support his § 1231(b)(3)(A) and CAT claims, and the IJ determined that this evidence was insufficient to meet Gelaneh’s burden of proof for either claim. Thus, the IJ concluded that Gelaneh’s “incredible testimony and the absence of any supporting documents establishing his identity (when he had ample opportunity to obtain them) leaves this court no choice but to deny his applications for withholding of removal and relief under the Torture Convention.” J.A. at 35.
In addressing the IJ’s denial of Gelaneh’s CAT claim, the BIA was required to review, and did review, the very same evidence that the IJ relied upon to deny Gelaneh’s § 1231(b)(3)(A) claim, and the BIA found that evidence wanting. See J.A. at 21 (“The testimony of the respondent and his witnesses, when assessed against the background and other documentary evidence in the record, is inadequate to meet the stringent burden of proving that it is more likely than not that he will face torture if returned to Ethiopia.”). The burden of establishing a risk of future torture is more stringent than is the burden of establishing a risk of future persecution. Lukwago v. Ashcroft, 329 F.3d 157, 182 (3d Cir.2003). Since Gelaneh presented the same evidence in support of both claims for relief, it is hardly likely that the BIA would have found that Gelaneh had failed to establish a clear probability of persecution but had succeeded in establishing a clear probability of torture.
In short, the record in this case forecloses the possibility that the BIA, on ampler review of Gelaneh’s claims, would have granted Gelaneh relief under § 1231(b)(3)(A). Accordingly, while the BIA ought to have been more thorough in addressing the question whether Gelaneh’s offense of possessing cocaine with intent to distribute was a “particularly serious” crime, we cannot say that Gelaneh was prejudiced as a result of the deficiencies in the BIA’s opinion.
Conclusion
Our review of the record establishes that, although the BIA’s treatment of one aspect of Gelaneh’s appeal gave rather short shrift to due process, Gelaneh has failed to demonstrate resultant prejudice. Accordingly, Gelaneh’s petition for review is denied.
