This case presents the question of whether the Attorney General may through an adjudicative decision create a strong presumption that a drug trafficking offense resulting in a sentence of less than five years is a “particularly serious crime” under 8 U.S.C. § 1231(b)(3)(B). Diego Miguel-Miguel, a native of Guatemala, petitioned for withholding of removal based
*943
upon his alleged fear that his life or freedom would be threatened if he were returned to Guatemala. The Board of Immigration Appeals (BIA) agreed, declaring Miguel eligible for withholding of removal, but nonetheless ordered him removed because it found that Miguel’s 1999 conviction for selling $20 of cocaine was a particularly serious crime. In so finding, the BIA followed the presumption set forth in the Attorney General’s opinion in
Matter of Y-L-
23 I. & N. Dec. 270 (Op. Att’y Gen.2002),
disapproved of on other grounds by Zheng v. Ashcroft,
BACKGROUND
Miguel was born in Guatemala and belongs to the indigenous Cakchiquel group. During the chaos of the country’s civil war, Miguel’s family was harassed by a guerilla group that believed that Miguel and his family supported the government. The guerillas initially demanded just money, but later threatened to kill Miguel if he did not join them. The guerillas took Miguel to the mountains, where they held him captive and forced him to serve as a lookout. During this time, Miguel witnessed the guerillas kill several people, and in one instance was forced to participate. Miguel says that he was afraid that if he did not assist the guerillas, they would kill him. After six months in captivity, Miguel was able to escape across the border into Mexico. He made his way to the United States, where he eventually applied for and was granted asylum in 1988.
In 1998, Miguel was charged in a California court for selling or transporting cocaine under California Health and Safety Code § 11352. 1 The facts of the offense are undisputed. While he was standing on the street with a group of men, an undercover agent approached Miguel and asked him for drugs. Miguel fetched .26 grams of rock cocaine from his associates and sold it to the agent for $20. Miguel pled guilty to the charges and received a sentence of time served (36 days), a fine of $200 and five years probation.
The Immigration & Naturalization Service (INS) placed Miguel in removal proceedings — triggering a series of hearings and appeals as the legal standards applied to Miguel’s case evolved over the course of the proceedings. At the outset, Miguel admitted the allegations in the Notice to Appear and applied for withholding of removal. In October 1999, an Immigration Judge (IJ) found that Miguel’s cocaine conviction did not preclude withholding of removal because the conviction was not for a “particularly serious crime” under 8 U.S.C. § 1231(b)(3)(B), as that term had been defined by the BIA in Matter of SS-, 22 I. & N. Dec. 458, 463-65 (BIA 1999) (en banc). The IJ nonetheless denied withholding of removal because, although Miguel had suffered past persecution, he had failed to provide documentary evidence that he continued to have a well-founded fear of future persecution. The BIA va *944 cated the decision and remanded, however, since a new INS regulation had changed the standard for evaluating changed circumstances.
On remand the IJ in August 2001, again held that changed circumstances precluded withholding of removal. On appeal, the BIA held that the IJ had again applied the wrong standard governing changed circumstances. Applying the proper standard, the Board in March 2003 found that Miguel had demonstrated that his life or freedom would be threatened if he returned to Guatemala. Thus, Miguel was eligible for withholding of removal. Meanwhile, however, the government had moved to remand the case to the IJ because on March 5, 2002, while Miguel’s appeal was pending, the Attorney General had issued his opinion in Matter of Y-L-. That opinion substantially altered the standard for determining whether a drug trafficking offense is “particularly serious” under § 1231(b)(3)(B). The BIA granted the motion to remand, sending the case back to the IJ to reconsider his prior determination that Miguel had not committed a particularly serious crime.
Applying the new standard, the IJ found that Miguel had indeed committed a particularly serious crime. The judge found that Miguel had failed to prove that his involvement in the cocaine transaction was “peripheral,” and thus under Matter of YL-, Miguel’s cocaine trafficking conviction was deemed particularly serious. The BIA affirmed without opinion. 2
Miguel’s habeas corpus petition filed in the United States District Court for the District of Arizona was denied. He then filed a timely appeal in this court. However, on May 11, 2005, the REAL ID Act, Pub.L. No. 109-13,119 Stat. 231, went into effect, transforming Miguel’s habeas appeal into a timely petition for review.
See Alvarez-Barajas v. Gonzales,
JURISDICTION
Before we reach the merits of Miguel’s arguments, we must address the government’s contention that we lack jurisdiction to do so. First, it argues that Miguel is a criminal alien under 8 U.S.C. § 1182(a)(2) and the BIA’s determination that he committed a particularly serious crime under § 1231(b)(3)(B) is an unreviewable exercise of discretion. See 8 U.S.C. § 1252(a)(2)(B) & (C). Our jurisdiction is not foreclosed, however, insofar as Miguel’s petition for review raises issues of law. See 8 U.S.C. § 1252(a)(2)(D). We hold that Miguel has done just that.
Miguel does
not
challenge the BIA’s conclusion that his offense was particularly serious under
Matter ofY-L-,
but instead argues that the Attorney General lacked the authority to issue
Matter of YL-,
or that
Y-L-
is invalid as applied to this case. These are pure questions of law and therefore we have jurisdiction to review them.
See Afridi v. Gonzales,
Second, the government argues that we lack jurisdiction because Miguel did not exhaust his argument that the BIA erred in failing to heed
Beltran-Zavala v. INS,
Accordingly, we turn to the merits of Miguel’s appeal.
DISCUSSION
I
Miguel makes a facial challenge to Matter of Y-L-, relying upon two premises. First, he asserts that Matter of Y-L- created what amounts to a per se rule that turns all drug trafficking offenses into particularly serious crimes under § 1231(b). Second, he contends that the Attorney General was forbidden from promulgating such a per se rule by Ninth Circuit law, the statute’s plain text, the Administrative Procedure Act (APA) and the Constitution. We reject Miguel’s first premise because Y-L- on its face purports to create only a strong presumption, not a per se rule. We thus need not decide whether the Attorney General can create per se rules under § 1231(b). Instead, we hold only that the Attorney General did not exceed his powers by creating the strong presumption set forth in Y-L-.
A
Consistent with the United States’ treaty obligations under the United Nations Protocol Relating to the Status of Refugees, 19 U.S.T. 6223 (1968), Congress has provided that an alien may not be removed to a nation in which his or her life or freedom would be threatened on a protected ground unless “the Attorney General decides that ... the alien, having been convicted by a final judgment of a particularly serious crime is a danger to the community.” 8 U.S.C. § 1231(b)(3)(B)(ii). The degree to which Congress has defined “particularly serious crime,” rather than leaving it for the Attorney General to define, has changed over time.
Before 1990, the Immigration and Nationality Act (INA) did not define the term at all.
See
8 U.S.C. § 1253(h)(2)(B) (1990). Rather, the definition of the term was developed by the BIA through adjudication. In
Matter of Frenteseu,
18 I.
&
N. Dec. 244 (BIA 1982), the BIA articulated a multi-factor test for determining whether a particular crime was particularly serious. The factors included “the nature of the conviction, the circumstances and underlying facts of the conviction, the type of sentence imposed, and, most importantly, whether the type and circumstances of the crime indicate that the alien will be a danger to the community.”
Id.
at 244. We approved of the
Frenteseu
factors in
Mahini v. INS,
*946 That same year, however, Congress amended the INA to provide that all aggravated felonies were particularly serious crimes. See Immigration Act of 1990, Pub.L. 101-649, § 515,104 Stat. 4978, 5053 (Nov. 29, 1990); 8 U.S.C. § 1258(h) (1991). This amendment overruled Frentescu and Beltran-Zavala by precluding case-by-case analysis for any aggravated felony. Then, in 1996, Congress again amended the INA’s definition of particularly serious crime. Congress eliminated the categorical rule, replacing it with a presumption that aggravated felonies are particularly serious. The presumption could be rebutted if the Attorney General determined it “necessary to ensure compliance with the 1976 United Nations. Protocol Relating to the Status of Refugees.” See Antiterrorism and Effective Death Penalty Act of 1996, Pub.L. No. 104-132, § 413(f), 110 Stat. 1214, 1269 (Apr. 24, 1996); 8 U.S.C. § 1253(h)(3)(B) (1996).
Just a few months later, however, Congress yet again amended the statute. Those amendments, which remain in effect today, eliminated the presumption and replaced it with a two-tiered approach. First, Congress made aggravated felonies for which the alien receives a sentence of imprisonment of five years or more particularly serious per se.
See
Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (IIRIRA), Pub.L. 104-208, div. C, sec. 305, § 241,110 Stat. 3009, 3009-602 (Sept. 30, 1996); 8 U.S.C. § 1231(b)(3)(B) (1997).
3
Second, however, the statute specifically provides that the creation of this class of per se particularly serious crimes “shall not preclude the Attorney General from determining that, notwithstanding the length of sentence imposed, an alien has been convicted of a particularly serious crime.”
Id.
In two en banc decisions, the BIA held that IIRIRA revived the
Frentescu
mode of case-by-case analysis for aggravated felony convictions resulting in sentences less than five years.
See Matter of L-S,
22 I.
&
N. Dec. 645, 649 (BIA 1999) (en banc);
Matter of S-S-,
22 I. & N. Dec. at 463-65. We agreed with that conclusion in
Afridi v. Gonzales,
The Attorney General’s 2002 opinion in Y-L- instructs the BIA to treat all drug trafficking offenses presumptively as “particularly serious crimes.” This presumption can be rebutted only in the “extraordinary,” “extenuating” and “compelling” case where a petitioner can demonstrate “at a minimum
(1) 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;
*947 (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.
Matter of Y-L-, 23 I. & N. Dec. at 274, 276-77 (emphasis in original). In addition, “[o]nly if all of these criteria were demonstrated by an alien would it be appropriate to consider whether other, more unusual circumstances ... might justify departure from” the presumption. Id. at 277 (emphasis in original). Thus Matter of Y-L- creates an extraordinarily strong presumption that drug trafficking offenses are particularly serious crimes. It therefore purports to overrule Matter of L-S, Matter of S-S- and Frentescu in part by precluding application of the Frentescu factors in most drug trafficking cases.
The Attorney General in
Y-L-
purported
not
to be creating a per se rule.
See Matter of Y-L-
23 I. & N. Dec. at 276 (stating that “I do not consider it necessary ... to exclude entirely the possibility of the very rare case where an alien may be able to demonstrate extraordinary and compelling circumstances that justify treating a particular drug trafficking crime as falling short of’ being a particularly serious crime). Presumably
Y-L-
will be interpreted consistent with this statement and there will be some cases in which its exception applies.
See, e.g., Lavira,
B
Neither our precedent nor the text of § 1231(b)(3) precluded the Attorney General from issuing
Matter of Y-L-.
In
Beltran-Zavala,
we made application of the
Frentescu
factors mandatory for two reasons. First, the BIA had consistently applied
Frentescu
and thus was bound by its own precedent to continue applying that analytical framework.
See Beltran-Zavala,
Second,
Beltran-Zavala
held that the structure of the statute precluded creation of per se particularly serious crimes because “[i]f Congress wanted to erect per se classifications of crimes precluding immigration and nationality benefits, it knew how to do so.”
Miguel argues that the plain text of the statute requires a Frentescu case-by-case analysis because it allows removal based on prior criminal conduct only where the Attorney General “determin[es] that ... an alien has been convicted of a particularly serious crime.” 8 U.S.C. § 1231(b)(3)(B) (emphasis added). Miguel interprets the reference to “an alien” rather than “a crime” to limit the scope of the Attorney General’s discretion to making determinations with regard to particular aliens on a case-by-case basis, not to designating per se crimes. This argument is misplaced because Matter of Y-L- does not purport to create a per se rule; and the statute’s text does not plainly foreclose the Attorney General’s creation of strong presumptions. Miguel’s interpretation of the statute, though plausible, is not the only permissible construction. The sentence immediately preceding the sentence Miguel relies upon also refers to “an alien” even though that sentence undisputedly establishes a per se class of particularly serious crimes. See 8 U.S.C. § 1231(b)(3)(B) (providing that “an alien who has been convicted of an aggravated felony (or felonies) for which the alien has been sentenced to an aggregate term of imprisonment of at least 5 years shall be considered to have committed a particularly serious crime” (emphasis added)). It is not clear that Congress would refer to “an alien” in one sentence to describe a per se rule that permits no case-by-case analysis but in the next sentence use “an alien” in order to specifically preclude the creation of a strong presumption that merely restricts the scope of case-by-case analysis. Thus § 1231(b)(3)(B) is ambiguous as to whether Congress meant to limit the Attorney General’s ability to create strong presumptions.
Because the statute’s text is not plain in either precluding or permitting the Attorney General to create strong presumptions, we must ask whether the Attorney General’s interpretation is impermissible.
See Aguirre-Aguirre,
Miguel contends that the Attorney General’s interpretation is impermissible because it conflicts with the United Nations High Commissioner for Refugees Handbook on Procedures and Criteria for Determining Refugee Status (Geneva 1992) (“UNHCR Handbook”). The Handbook states that refugees may be returned to countries in which they face persecution only in “extreme cases,” and suggests that a “serious” crime must be “a capital crime or a very grave punishable act.” UNHCR Handbook,
supra,
at ¶ 154-55.
4
Admittedly, the creation of a strong presump
*949
tion that all drag trafficking offenses— even relatively minor ones — are particularly serious is in tension with the Handbook’s definition. We view the UNHCR Handbook as “persuasive authority in interpreting the scope of refugee status under domestic asylum law.”
Ndom v. Ashcroft,
We hold that the Attorney General’s construction of § 1231(b)(3)(B) as providing him with discretion to create a strong presumption that drug trafficking offenses are particularly serious crimes is not impermissible. Under Chevron, we therefore defer to that construction. Accordingly, after Matter of Y-L-, a Frentescu analysis is no longer required with regard to drug trafficking offenses. 5
C
Miguel next argues that even if the Attorney General’s interpretation is permissible in light of the statutory text, it nonetheless violates the Fifth Amendment Due Process Clause by creating a de facto per se rule. Miguel relies upon
Chong v. INS,
Miguel does not claim his procedural due process rights were violated, and even if he had we would reject that claim. Miguel received all the process to which he was due, i.e. “a full and fair hearing of his claims and a reasonable opportunity to present evidence on his behalf.”
Ladha v. INS,
D
Miguel next argues that
Matter of Y-L-
sets forth an unconstitutionally vague rule. However, constitutional vagueness requirements apply only to “vague statutory language” or to “unforeseeable and retroactive judicial expansion of statutory language that appears narrow and precise on its face.”
Rogers v. Tennessee,
E
Miguel also argues that
Matter of Y-L-
is invalid because it is a legislative rule under the APA and therefore the Attorney General could not issue it without first engaging in notice-and-comment rule-making procedures.
See Hemp Indus. Ass’n v. DEA,
II
Miguel argues that even if
Matter of Y-L-
is valid on its face, the BIA nonetheless is barred from applying it retroactively to his case by
Montgomery Ward & Co., Inc. v. FTC,
In
SEC v. Chenery Corp.,
(1) whether the particular case is one of first impression,
(2) whether the new rule represents an abrupt departure from well established practice or merely attempts to fill a void in an unsettled area of law,
(3) the extent to which the party against whom the new rule is applied relied on the former rule,
(4) the degree of the burden which a retroactive order imposes on a party, and
(5) the statutory interest in applying a new rule despite the reliance of a party on the old standard.
Id.
at 390. We adopted the
Retail, Wholesale
factors in
Montgomery Ward,
To begin, this is not a case of first impression. Before
Matter of Y-L-,
both the BIA and this court had affirmed
Fren-tescu’s
case-by-ease mode of analyzing whether a particular alien had committed a particularly serious crime, including drug trafficking offenses.
See Beltran-Zavala,
The second factor also favors Miguel. That factor “requires the court to gauge the unexpectedness of a rule and the ex
*952
tent to which the new principle serves the important but workaday function of filling in the interstices of the law.”
Clark-Cowl-itz Joint Operating Agency v. FERC,
The third factor also favors Miguel. “There can be little doubt that, as a general matter, alien defendants considering whether to enter into a plea agreement are acutely aware of the immigration consequences of their convictions.”
INS v. St. Cyr,
The fourth factor strongly favors Miguel. We have previously held that deportation alone is a substantial burden that weighs against retroactive application of an agency adjudication.
See Ruangswang,
Only the final factor favors the government. By amending section § 1231(b)(3)(B), Congress gave the Attorney General substantial discretion with regard to particularly serious crime determinations. In Y-L-, the Attorney General singled out narcotics trafficking as particularly serious, both in the interest of public safety and in bringing uniformity to the law. See Matter of Y-L- 23 I. & N. Dec. at 273 (stating that Frentescu regime “has led to results that are both inconsistent and ... illogical”). But these interests are substantially served by prospective application of Matter of Y-L-. Forbidding the Attorney General from applying Y-L- retroactively in this ease therefore does not severely limit his efforts to pursue the statutory mandate.
*953 Accordingly, because the Montgomery Ward analysis tilts decidedly in Miguel’s favor, we hold that retroactive application of the Matter of Y-L- test to his case was impermissible. 6
CONCLUSION
For the foregoing reasons, we grant the petition for review and remand to the BIA for further proceedings.
PETITION GRANTED; REMANDED.
Notes
. Section 11352 provides in relevant part:
[E]very person who ... sells ... or offers to ... sell [cocaine], unless upon the written prescription of a physician, dentist, podiatrist, or veterinarian licensed to practice in this state, shall be punished by imprisonment in the state prison for three, four, or five years.
Miguel was also convicted in 1998 of a drug possession offense under California Health & Safety Code § 11350(a). That offense, however, is not before us because Miguel's removal order is predicated only on his cocaine sale conviction. See Lavira v. Attorney Gen. of United States,478 F.3d 158 , 162 (3d Cir.2007).
. Because it is not before us, we take no position on whether the BIA's agreement with the IJ that Miguel's involvement in the underlying offense was not peripheral was correct.
. The current text provides that an alien may be deported, notwithstanding a threat to his life or freedom, if "the Attorney General decides that ... the alien, having been convicted by a final judgment of a particularly serious crime is a danger to the community of the United States.” 8 U.S.C. § 1231(b)(3)(B)(ii) (2007). The statute further provides:
For purposes of clause (ii), an alien who has been convicted of an aggravated felony (or felonies) for which the alien has been sentenced to an aggregate term of imprisonment of at least 5 years shall be considered to have committed a particularly serious crime. The previous sentence shall not preclude the Attorney General from determining that, notwithstanding the length of sentence imposed, an alien has been convicted of a particularly serious crime.
8 U.S.C. § 1231(b)(3)(B) (2007).
. The Handbook does not directly define particularly serious crime, but does comment on the meaning of "serious” in the context of defining the term "serious non-political crime” in Article lF(b) of the 1951 United *949 Nations Convention Relating to the Status of Refugees. See Frentescu, 18 I. & N. Dec. at 245-47.
. Insofar as Miguel also argues that Matter of Y-L-'s ultimate conclusion — that most drug trafficking offenses are particularly serious — is impermissible, we reject that argument. The Attorney General justified the YL- presumption based upon the BIA’s prior treatment of drug trafficking offenses as “inherently ... particularly serious,” Congress’ imposition of harsh punishment for such offenses and the threats to public safety posed by drug use and the illegal drug trade. See 23 I. & N. Dec. at 274-76 (quoting Matter of U-M-, 20 I. & N. Dec. 327, 330-31 (BIA 1991)). The Attorney General’s choice to so exercise his discretion was not impermissible in light of the statute’s text, structure or purpose.
. The government contends that even if the BIA erred by applying Y-L- retroactively, we need not remand because the BIA held that Miguel failed to demonstrate future persecution justifying withholding of removal. This flatly misrepresents the record: the BIA specifically held that Miguel had demonstrated past persecution and that the government failed to rebut the presumption that he would be persecuted in the future. Thus, the Board held, petitioner "demonstrated his eligibility for withholding of removal under the Act,” aside from the issues involving Y-L-.
