ORDER DENYING MOTION FOR APPROPRIATE RELIEF (SENTENCE REDUCTION) BASED UPON PETITIONER’S DEPORTA-BLE STATUS AS AN ALIEN AND EXTRAORDINARY CIRCUMSTANCES
After clarifying the legal basis for the Defendant’s motion for sentence reduction, the Court concludes that the Defendant’s amended petition for relief is a petition under 28 U.S.C. § 2255 and, as such, is barred as a second or successive petition.
I. STATEMENT OF FACTS
On February 4, 1999, the late Morton A. Brody, United States District Judge, sentenced Enrique Arjuro Reyes-Cabrera to 188 months incarceration, supervised release of 72 months, and a $400 special assessment for four drug trafficking crimes. Mem. of Sentencing J. (Docket # 17); J. (Docket # 18). On August 18, 2008, Mr. Reyes-Cabrera moved for reduction of sentence.1 Mot. for Appropri*293ate Relief (Sentence Reduction) Based Upon Pet’r’s Deportable Status as an Alien and Extraordinary Circumstances (Docket # 78) (Def.’s Mot.). In response, the Government moved for summary dismissal. Mot. for Surnm. Dismissal (Docket # 81). Mr. Reyes-Cabrera replied, and moved to amend his original motion to include different grounds for relief, and a request that the Court transfer his motion to the First Circuit.2 Mot. in Reply to the Gov’t and a Request for Leave of Court to Amend the Pleadings Pursuant to F.R. Civ. P. 15(a)(2) (With Sworn Aff.) (Docket #s 82, 83) (Def.’s Reply and Mot. to Amend). Further replies providing supplemental authority followed. Supplemental Authorities for Am. Br. Pg. 6 (Docket # 84); Supplemental Authorities for Am. Br. Pg. 8, 9 (Docket # 85).
II. DISCUSSION
Mr. Reyes-Cabrera’s petition does not specify under which procedural rule or substantive law he is proceeding, and it is difficult to categorize his broad post-conviction request that the Court exercise its “inherent powers” to reduce his sentence. Def.’s Mot. at 1. Nevertheless, however denominated, the petition fails. The most likely procedural vehicle is Rule 35(b), which allows a post-sentence motion for reduction of sentence. See Fed.R.Crim.P. 35(b). But, Rule 35(b) expressly provides that only the Government may move for a Rule 35(b) sentence reduction; the Defendant may not. Accordingly, if filed under Rule 35(b), the motion is not authorized and must be denied.
Another possibility is a petition under 28 U.S.C. § 2255. Section 2255 applies to
A prisoner in custody under sentence of a court established by Act of Congress claiming the right to be released upon the ground that the sentence was imposed in violation of the Constitution or laws of the United States, or that the court was without jurisdiction to impose such sentence, or that the sentence was in excess of the maximum authorized by law, or is otherwise subject to collateral attack....
28 U.S.C. § 2255(a). In United States v. Barrett, 178 F.3d 34, 42 (1st Cir.1999), the First Circuit explained how to determine whether a prisoner’s petition is a § 2255 petition, and subject to that section’s procedural requirements. Mr. Barrett, who at the time of his petition was in custody serving a federal sentence for bank robbery, moved the sentencing court to vacate or set aside his sentence, asserting claims of illegality under Brady v. Maryland and the Jencks Act, 18 U.S.C. § 3500. Barrett, 178 F.3d at 38-39, 42. The First *294Circuit concluded that his petition, so situated, was a § 2255 petition. Id.
Mr. Reyes-Cabrera’s motion and reply are not as easily confined. He contends that the Court should reduce his sentence after taking into account his status as a deportable alien, the collateral effects of that status on execution of his sentence, and his likely post-release detention pending deportation. Def.’s Mot. at 8-5. He further contends that a “downward departure” is warranted because he is now forty-seven years old, presents no danger to society, and is unlikely to return to a life of crime because he is rehabilitated. Id. at 6-7, 9-10. Finally, he argues that the Court should reduce his sentence because his family faces extraordinary hardship, including the poor health of his eighty-four year old father. Id. at 8. Although he also briefly reiterates some claims previously resolved against him, such as that his plea was not knowing and intelligent, id. at 5-6, the tenor of his motion is that extraordinary circumstances warrant a reduction in his sentence. The Court is unclear whether, as the Government argues, § 2255 applies to Mr. Reyes-Cabrera’s original motion, as the First Circuit found it did to Mr. Barrett’s petition in Barrett.
Mr. Reyes-Cabrera, however, moved to amend his motion, Def.’s Reply and Mot. to Amend, which the Government stated it does not oppose. Unlike his original motion for reduction of sentence, Mr. Reyes-Cabrera’s amended motion focuses on arguments previously rejected (or raises arguments that could have been raised before) regarding the illegality, unconstitutionality, or unfairness of his conviction, sentence, and adverse dispositions of his collateral attacks.3 As amended, Mr. Reyes-Cabrera’s motion is more comfortably situated under § 2255: he is in custody serving a federal sentence and has petitioned the sentencing court for relief based on the illegality or unconstitutionality of his conviction and sentence.
However, Mr. Reyes-Cabrera previously has filed at least two § 2255 petitions. He filed his first on December 13, 1999, Def.’s 2255 Pet., which the Court and the First Circuit denied. Rec. Dec. on Def.’s 2255 Pet.-, Order Affirming Rec. Dec.-, Order Denying Certificate of Appealability (Docket # 39); Reyes-Cabrera v. United States, No. 00-1563 (1st Cir. July 10, 2001) (Docket #49). His second — filed almost six years later in the guise of a motion for Rule 60(b) relief from that denial — was no more successful. See Reyes-Cabrera v. United States, No. 06-1555 (1st Cir. June 20, 2006) (denying certificate of appealability, terminating the appeal, and deeming the Rule 60(b) motion a second or successive § 2255 petition because it “challenge[d] the validity of the underlying criminal judgment”); see Munoz v. United States, 331 F.3d 151, 153 (1st Cir.2003) (holding that a Rule 60(b) motion “for re*295lief from a judgment previously entered in a section 2255 case should be treated as a second or successive habeas petition if— and only if — the factual predicate set forth in support of the motion constitutes a direct challenge to the constitutionality of the underlying conviction”) (internal quotation omitted).
The Court concludes that Mr. Reyes-Cabrera’s motion, as amended, is a second or successive § 2255 petition that the Court may consider only if a panel of the First Circuit certifies that it contains “newly discovered evidence or ... a new rule of constitutional law made retroactive by the Supreme Court to cases on collateral review.” Munoz, 331 F.3d at 153; 28 U.S.C. § 2255(h). Mr. Reyes-Cabrera has not suggested that he has sought or obtained such certification.4
Finally, the petition may seek to modify the sentence under 18 U.S.C. § 3582. If so, Mr. Reyes-Cabrera has failed to allege that any of the narrow circumstances under which the Court could consider such a motion exist in this case. See 18 U.S.C. § 3582(c); United, States v. Griffin, 524 F.3d 71, 83-84 (1st Cir.2008). The general rule is that a “court may not modify a term of imprisonment once it has been imposed.” 18 U.S.C. § 3582(c). The statute allows such a reduction only in rare circumstances after procedural prerequisites have been fully satisfied. For example, Mr. Reyes-Cabrera claims that his father’s poor health justifies a reduction in his sentence. Under the law, Mr. Reyes-Cabrera is not authorized to file such a motion; the motion must be filed by the Director of the Bureau of Prisons pursuant to 18 U.S.C. § 3582(e)(1)(A) for reasons that comport with the statute. See 18 U.S.C. § 3582(c)(l)(A)(i)-(ii). The motion on its face fails to comply with the statutory requirements.
III. CONCLUSION
The Court GRANTS Enrique Arjuro Reyes-Cabrera’s Request for Leave to Amend the Pleadings Pursuant to F.R. Civ. P. 15(a)(2) (Docket # 83). The Court DENIES Mr. Reyes-Cabrera’s Motion for Appropriate Relief (Sentence Reduction) Based Upon Petitioner’s Deportable Status as an Alien and Extraordinary Circumstances (Docket # 78), as amended by Mr. Reyes-Cabrera’s Motion in Reply to the Government (Docket # 82).
SO ORDERED.
