                   Appeals from the United States District Court
                        for the Northern District of Texas
                             USDC No. 3:09-CV-1024
                              USDC No. 3:09-CV-981


Before JOLLY, WIENER, and ELROD, Circuit Judges.
PER CURIAM:*
       Eric Martin Matthews, federal prisoner # 75804-004, was convicted in the
Southern District of Florida of using a computer to entice a minor to engage in
sexual activity in violation of 18 U.S.C. § 2422(b) and distributing child
pornography in violation of § 2252(a)(2) and sentenced to a 262-month term of
imprisonment and a life-term of supervised release.                  Matthews filed two



       *
         Pursuant to 5TH CIR. R. 47.5, the court has determined that this opinion should not
be published and is not precedent except under the limited circumstances set forth in 5TH CIR.
R. 47.5.4.
                                  No. 09-10822
                                c/w No. 09-10824

petitions in the district court in the Northern District of Texas under 28 U.S.C.
§ 2241, challenging his life-term of supervised release and certain conditions of
supervised release.    The district court dismissed the petitions for lack of
jurisdiction. Matthews moves this court for leave to proceed in forma pauperis
(IFP) on appeal. He challenges the district court’s denial of IFP status and
certification that his appeals would not be taken in good faith. See Baugh v.
Taylor, 

, 202 (5th Cir. 1997); FED. R. APP. P. 24(a). Matthews’s
motion for a default judgment is DENIED.
      A movant for leave to proceed IFP on appeal must show that he is a
pauper and that the appeal presents a nonfrivolous issue. See Carson v. Polley,

, 586 (5th Cir. 1982). A district court may, by providing written
reasons certifying that the appeal is not taken in good faith, deny a motion for
leave to appeal IFP. 

; FED. R. APP. P. 24(a). The
appellant may challenge the district court’s certification decision by filing an IFP
motion in this court. 

; FED. R. APP. P. 24(a)(5).
      To the extent that Matthews argues that the district court should not have
dismissed his petitions sua sponte, federal courts have the obligation to examine
sua sponte the basis of their jurisdiction. United States v. De Los Reyes, 

, 757 (5th Cir. 1988). To the extent that Matthews suggests that his
petitions should have been construed as motions to modify his conditions of
release under 18 U.S.C. § 3583(e)(2), a district court lacks jurisdiction under
§ 3583(e)(2) to modify conditions of supervised release on grounds of illegality.
United States v. Hatten, 

, 886 (5th Cir. 1999) (order of restitution).
      As the district court observed, Matthews’s § 2241 petitions challenged the
supervised release component of his federal sentence. A § 2241 petition that
“attacks errors that occur at trial or sentencing is properly construed under
§ 2255.” Tolliver v. Dobre, 

, 877-78 (5th Cir. 2000); see also
Christopher v. Miles, 

, 381-82 (5th Cir. 2003). Matthews must meet

                                         2

                                 c/w No. 09-10824

the requirements of the savings clause of § 2255(e) to raise his claims under
§ 2241. See Kinder v. Purdy, 

, 212 (5th Cir. 2000); see also Pack v.
Yusuff, 

, 452 (5th Cir. 2000); § 2255(e). Matthews bears the burden
of demonstrating that “the remedy by motion [under § 2255] is inadequate or
ineffective to test the legality of his detention.” § 2255(e); see also 

. Relief under § 2255 is not “inadequate or ineffective” for purposes of the
savings clause merely because the prisoner has filed a prior unsuccessful § 2255
motion or is unable to meet the requirements for filing a second or successive
§ 2255 motion. 

. As Matthews has not met the
requirements of the savings clause, the district court did not err in concluding
that Matthews could not bring his claims under § 2241. See 

.
       “A section 2241 petition that seeks to challenge the validity of a federal
sentence must either be dismissed or construed as a section 2255 motion.” 

. The district court correctly noted that jurisdiction over a § 2255
motion lies in the district where the movant’s sentence was imposed. See 

(“A section 2255 motion must be filed in the sentencing court.”); see also Ojo
v. INS, 

, 683 (5th Cir. 1997). Matthews was sentenced in the
Southern District of Florida. Therefore, the district court lacked jurisdiction to
construe Matthews’s petitions as arising under § 2255. See 

.
       Matthews has not shown that his appeals present a nonfrivolous issue.
See Howard v. King, 

, 220 (5th Cir. 1983). Accordingly, his IFP
motion is denied, and his appeals are dismissed as frivolous. See 

n.24; 5TH CIR. R. 42.2.
       MOTION TO PROCEED IFP DENIED; MOTION FOR A DEFAULT
JUDGMENT DENIED; APPEAL DISMISSED.
