OPINION OF THE COURT
Neville Sylvester Leslie petitions for review of a final order of removal of the Board of Immigration Appeals (“Board”), arguing that the Immigration Judge’s (“IJ”) failure to advise him of the availability of free legal services, as required under 8 C.F.R. § 1240.10(a)(2)-(3), entitles him to a new removal hearing under
United States ex rel. Accardi v. Shaughnessy,
I.
On October 2, 1998, Leslie, a native and citizen of Jamaicа and a lawful permanent resident of the United States, pled guilty to the felony offense of conspiracy to possess and distribute 50 grams or more of “crack” cocaine, in violation of 21 U.S.C. §§ 841(a)(1) and 846, and was sentenced to 168 months’ incarceration. While serving his sentence, Leslie was issued a Notice to Appear by the Department of Homeland Security (“Department”), charging him with being subject to removal under subsections 237(a) (2) (A) (iii) (aggravated felony conviction) and 237(a)(2)(B)(i) (controlled substance conviction) of the Immigration and Nationality Act (“INA”), 8 U.S.C. § 1227(a)(2)(A)(iii) & 1227(a)(2)(B)(i). The notice was sent on February 21, 2008, but did not include the time or date of the hearing. (App.131.) The notice referred to a “list of qualified attorneys and organizations who may be available to represent you at no cost,” which was to be provided with the notice. Although a checkmark appeared beside the box that read “Attached *174 is a list of organizations and attorneys which provide free legal services,” the list does not appear in the administrative record. (App.132.)
The record contains a second notice, dated April 8, 2008. It states the date, time, and place of Leslie’s removal hearing, but was delivered to “York ICE — Clinton” in York, Pennsylvania. (App.129.) The “Legal Services List” box is not checked. (App.129.) On April 8, 2008, Leslie was serving his criminal sentence at Clinton County Prison in McElhattan, Pennsylvania. According to Leslie, he was transported by U.S. Immigration and Customs Enforcement officers from Clinton County Prison to York County Prison on April 15 or 16, 2008. (App. 118; Pet’r Br. 7.) Leslie appeared before an IJ at York County Prison on April 16, 2008. 1 When the IJ inquired if Leslie was seeking an attorney, he replied, “I don’t have the money, Sir.” (App.115.) The IJ did not explain the availability of free legal resources, nor did he ascertain whether Leslie had received the “Legal Services List.” The IJ ordered Leslie removed as an alien convicted of an aggravated felony. (App.111-113.)
Leslie timely appealed to the Board, which issued a decision on July 11, 2008, dismissing his appeal. (App. 13-14.) Leslie filed a petition for review in our Court on July 21, 2008, and filed a motion to stay his removal on July 24, 2008. On August 14, 2008, this Court granted his request for a stay of removal and appointed him counsel.
II.
The Government’s sole argument is that we lack jurisdiction to review Leslie’s petition under INA section 242(a)(2)(C), 8 U.S.C. § 1252(a)(2)(C).
2
We disagree. Although 8 U.S.C. § 1252(a)(2)(C) limits our jurisdiction over final decisions ordering removal based on the commission of an aggravated felony or a controlled substance offense, we retain jurisdiction over constitutional claims and questions of law.

8 U.S.C. § 1252(a)(2)(D);

III.
A.
We first address Leslie’s contention that his removal order is invalid because the IJ failed to comply with regulations promulgated by the Attorney General to protect his right to counsel. In particular, Leslie contends that the IJ violated 8 C.F.R. § 1240.10(a)(2)-(3), which directs that “[i]n a removal proceeding, the immigration judge shall” “[a]dvise the respondent of the availability of free legal serviсes provided by organizations and attorneys ... located in the district where the removal hearing is being held” and shall “[ascertain that the respondent has received a list of such programs[.]” Although allegations of due process violations must ordinarily be accompanied by “an initial showing of substantial prejudice,”
Khan v. Att’y Gen.,
B.
We begin with the long-settled principle that rules promulgated by a federal agency that regulate the rights and interests of others are controlling upon the agency.
Columbia Broad. Sys., Inc. v. United States,
After
Accardi,
the Court continued to require agencies to comply with their promulgated regulations, without requiring petitioners to make a showing of prejudice. In
Service v. Dulles,
In
American Farm Lines v. Black Ball Freight Service,
Courts have taken diverse approaches to reconciling the tension between American Farm Lines and Accardi, some imposing explicit prejudice requirements, see, e.g.,
United States v. Calderon-Medina,
This Court has never explicitly formulated a framework for determining when judicial relief for a regulatory violation must be premised upon a showing of prejudice. See
Ponce-Leiva v. Ashcroft,
[W]hen a regulation is promulgated to protect a fundamental right derived from the Constitution or a federal statute, and the INS fails tо adhere to it, the challenged deportation proceeding is invalid and a remand to the agency is required. This may well be so even when the regulation requires more than would the specific provision of the Constitution or statute that is the source of the right. On the other hand, where an INS regulation does not affect fundamental rights derived from the Constitu *178 tion or a federal statute, we believe it is best to invalidate a challenged proceeding only upon a showing of prejudice to the rights sought to be protected by the subject regulation.
Id. (citation omitted).
Chong stands for the proposition that a violation of a regulation that does not protect fundamental constitutional or statutory rights is reversible error only with a showing of prejudice.

See Chong,
We believe that this rule comports with Accardi and American Farm Lines. Accardi teaches that some regulatory violations are so serious as to be reversible error without a showing of prejudice, and
American Farm Lines,
397 U.S at 539,
We take additional guidance from Supreme Court teachings emphasizing the importance of the root of the regulation in question when determining appropriate judicial relief for rеgulatory violations. In
Morton v. Ruiz,
Additionally, we note that our sister Courts of Appeals have generally required stricter compliance with regulations born of statutory or constitutional rights.
See Battle v. FAA,
Although we agree that prejudice need not be shown when alleged regulatory violations implicate fundamental statutory or constitutional rights, we reject Leslie’s assertion that the proper standard is set forth in
Montilla,
Fоr the sake of emphasis we repeat: we hold that when an agency promulgates a regulation protecting fundamental statutory or constitutional rights of parties appearing before it, the agency must comply with that regulation. Failure to comply will merit invalidation of the challenged agency action without regard to whether the alleged violation has substantially prejudiced the complaining party.
C.
We turn now to the question whether regulation 8 C.F.R. § 1240.10(a)(2)-(3), which was indisputably violated in this case, protects a fundamental statutory or constitutional right, such that we may order a new removal prоceeding without a showing of prejudice. We hold that it does.
Regulation 8 C.F.R. § 1240.10(a)(2)-(3) requires that “[i]n a removal proceeding, the immigration judge shall” “[ajdvise the respondent of the availability of free legal services provided by organizations and attorneys ... located in the district where the removal hearing is being held[,]” and “[ascertain that the respondent has received a list of such programs[.]” 8 C.F.R. § 1240.10(a)(2)-(3). This regulation derives from 8 U.S.C. § 1362, which provides that “[i]n any removal proceedings before an immigration judge ... June 21, 2010, the person concerned shall have the privilege of being represented (at no expensе to the Government) by such counsel ... as he shall choose.” It is also mandated by 8 U.S.C. § 1229a(b)(4)(A), which commands the Attorney General to adopt regulations ensuring that an alien “shall have the privilege of being represented, at no expense to the Government, by counsel of the alien’s choosing who is authorized to practice in such proceedings.” It is plain that 8 C.F.R. § 1240.10(a)(2)-(3) protects an alien’s right to counsel at removal hearings, which is manifestly a statutory right.
This statutory ¿md regulatory right to counsel is also derivative of the
*181
due process right to a fundamentally fair hearing.
See Borges v. Gonzales,
The right to counsel is a particularly important procedural safeguard because of the grave consequences of removal. In this case, where removal is predicated on the commission of an aggravated felony, see 8 U.S.C. § 1227(a)(2)(A)(iii), the draconian and unsparing result of removal is near-total preclusion from readmission to the United States, with only a remote possibility of return after twenty years. Under 8 U.S.C. § 1182(a)(9)(A)(ii), an alien removed after conviction of an aggravated felony is inadmissible “at any time[.]”
5
Removal “visits a great hardship on the individual and deprives him of the right to stay and live and work in this land of freedom. That deportation is a penalty—at times a most serious one — cannot be doubted.”
Bridges v. Wixon,
Compounding the grave consequences of removаl, many aliens subject to removal proceedings are unfamiliar with the complex adjudicatory process by which immigration laws are enforced. Many courts have recognized that “our immigration statutory framework is notoriously complex.” E.g.,
N-A-M v. Holder,
*182 Regulation 8 C.F.R. § 1240.10(a)(2)-(3) was manifestly designed to protect an alien’s fundamental statutory and constitutional right to counsel at a removal hearing. 6 Recognizing the difficulty aliens might have in locating and accessing counsel, the regulation reflects the agency view that some aliens may only be able to obtain counsel through low-cost or free legal services. We can think of no better demonstration of that difficulty than Leslie’s unrepresented appearance at his removal hearing and his statement that he could not afford counsel. Here it was paramount that the IJ comply with § 1240.10(a)(2)-(3)’s mandate to “[a]dvise the respondent of the availability of free legal services” and to “[a]scertain that the respondent has received a list of such рrograms[.]” The IJ’s failure to apprise Leslie of the availability of free legal services, as required under the regulations, renders invalid the subsequently entered removal order, without regard to Leslie’s ability to demonstrate substantial prejudice.
IV.
Leslie contends additionally that he is entitled to a new removal hearing because his Notice to Appear was deficient, in violation of his due process rights and the applicable statute. Pursuant to 8 U.S.C. § 1229(a)(1)(G)(i), an alien is entitled to written notice of removal proceedings specifying, among other things, “[t]he time and place at which the proceеdings will be held.” From the record presented, we can conclude that Leslie was transported from Clinton County Prison to York County Prison on April 15 or April 16 and was present for his April 16 hearing at York County Prison. He received, at most, one day of notice as to the time and place of his removal hearing, and this notice was perhaps effected only by physical transport from one institution to another.
Because we grant Leslie’s petition on the basis of the IJ’s violation of 8 C.F.R. § 1240.10(a)(2)-(3), we need not decide whether this blatantly tardy notice was constitutionally deficient. Parenthetically, we note that we find it difficult tо believe that a notice, issued under 8 U.S.C. § 1229(a)(1)(G)®, would satisfy the Due Process Clause without affording an alien adequate time and opportunity to prepare arguments on his or her own behalf. Because we grant the petition on other grounds, it is not necessary to rule specifically in this case that subsumed in the requirement of notice is a critical timeliness element.
See Abdulai v. Ashcroft,
V.
Because the regulation at issue, requiring the IJ to inform Petitioner of the availability of free legal services, prоtects the fundamental right to counsel at removal hearings, we will enforce it without regard to the existence vel non of prejudice resulting from its violation. It is imperative that the IJ comply scrupulously with these regulations, promulgated to ensure *183 the fundamental fairness of the process by which aliens are removed. As it is undisputed that the IJ entered Leslie’s removal order after failing to comply with the requirements of 8 C.F.R. § 1240.10(a)(2)-(3), we will grant the petition for review, vacate the order of the Board, and remand for further proceedings in accordance with the foregoing. 7
Notes
. It is not clear from the record precisely when Leslie became apprised of the April 16 hearing. According to the Government, "[b]y virtue of his detention status, [Leslie] was conveyed to his hearing before the immigration judge on April 16, 2008, and informed of the nature of those proceedings.” (Resp’t Br. 13.)
. Not only is this manifestly incorrect, but the Government's failure to assist the Court in evaluating the specifics of Petitioner’s argument required the Court to conduct a special, searching analysis of Petitioner's contentions before, during and after oral argument. As to that portion of Rule 31(a)(1), Federal Rules of Appellate Procedure, directing an appellee or respondent to "serve and file a brief within 30 days after appellant's [or petitioner’s] brief is served,” we construe the word "brief” to require that the answering brief address every relevant, non-frivolous issue presented by the appellant or petitioner. Litigants should also be mindful of the proper construction of this term when considering Rule 31(c)'s directive that an appellee or respondent "who fails to file a brief will not be heard at oral argument unless the court grants permission.”
"It is well settled that an appellant's failure to identify or argue an issue in his opening brief constitutes waiver of that issuе on appeal.”
United States v. Pelullo,
. The Government makes no argument that the IJ complied with the regulation in question. Nonetheless, we have reviewed the record and we conclude that the sum total of the IJ's colloquy with Leslie regarding his right to counsel is as follows:
Q. "Mr. Leslie, you have a right to be represented by an attorney at no expense to the United States Government. If you want a lawyеr, you must find the attorney yourself. The Court may not by law appoint an attorney for you. Do you understand?”
A. "Yes.”
Q. "Are you seeking an attorney?”
A. "I don't have the money, Sir.”
Q. "All right. Do you want to proceed and answer questions of the Court today?”
A. "Yeah, because I, I — I'd become a National in this country.”
(App.115.)
. We must take this opportunity to rectify a mistake in
Chong,
where we directly quote an erroneous statement from a Fourth Circuit
case
—Morgan.
See Chong,
Although the Accardi doctrine originally contemplated that an agency's failure to comply with its own rules automatically would nullify its actions, the Supreme Court since has "required that claimants demonstrate prejudice resulting from the violation unless '[t]he rules were not intended primarily to confer important procedural benefits upon individuals in the face of otherwise unfettered discretion’ or unless 'an agency required by rule to exercise independent discretion has failed to do so.’ ” Morgan,193 F.3d at 267 (quoting Am. Farm Lines v. Black Ball Freight Serv.,397 U.S. 532 , 538-39,90 S.Ct. 1288 ,25 L.Ed.2d 547 (1970)). Id. (emphases added). The Morgan case’s first use of "unless” renders its characterization of the American Farm Lines language erroneous. Under American Farm Lines,397 U.S. at 538-539 ,90 S.Ct. 1288 , rules intended to provide "procedural benefits upon indiv[i]duals in the face of otherwise unfettered discretion” can be "exempt ... from the general principle” that a prejudice showing is required. The case American Farm Lines cites for this proposition, Vitarelli,359 U.S. 535 ,79 S.Ct. 968 ,3 L.Ed.2d 1012 , confirms this interpretation. As previously discussed, in Vitarelli, procedural rules for federal agency discharge proceedings were violated. Ordinarily, the agency had unfettered discretion to discharge employees; however, the agency had instituted "procedural safeguards” where the agency's reason for discharge was a concern for national security. Id. at 540,79 S.Ct. 968 . Given the circumstances, the Court stated that "scrupulous observance of departmental procedural safeguards is clearly of particular importance.” Id. The Court did not mention any prejudice requirement, but instead held that the employee’s dismissal for national security reasons was illegal given the agency’s procedural violations. Id. at 545,79 S.Ct. 968 .
. See also 8 U.S.C. § 1182(a)(9)(A)(iii); 8 C.F.R. § 212.2(a) (providing that Attorney General may consent to readmission twenty years after aggravated-felony removal).
. Our conclusion accords with
Picca v. Mukasey,
. We recognize the contribution of pro bono services rendered by appointed counsel for the Petitioner, and note our formal appreciation for counsels’ advocacy.
