    UNITED STATES OF AMERICA, Plaintiff—Appellee, v. Juan LOPEZ-PEREZ, Defendant—Appellant.
    No. 02-10400.
    D.C. No. CR-01-00357-DCB.
    United States Court of Appeals, Ninth Circuit.
    Submitted June 10, 2003.
    
    Decided June 13, 2003.
    Before T.G. NELSON, HAWKINS, Circuit Judges, and ZILLY, District Judge.
    MEMORANDUM 
    
    Juan Lopez-Perez was indicted and convicted of illegal reentry after removal. He appeals the district court’s denial of his motion to dismiss the indictment. We have jurisdiction pursuant to 28 U.S.C. § 1291, and we affirm.
    Because the parties are familiar with the facts, we do not recite them here. We conclude that Lopez-Perez’s waiver, at the underlying removal hearing, was not knowing and intelligent. The immigration judge (“IJ”) erroneously failed to inform Lopez-Perez of the possibility that he might have a claim for derivative citizenship. A “reasonable possibility” existed that Lopez-Perez had such a claim, based on the conflicting record before the IJ.
      We reject Lopez-Perez’s argument regarding the right to obtain an attorney because he did not raise it before the district court.
    
    Although we conclude that Lopez-Perez’s waiver was not knowing and intelligent, and a due process violation therefore occurred, we nonetheless affirm because Lopez-Perez has not shown prejudice from the violation. Indeed, although counsel in Lopez-Perez’s criminal case conducted an investigation, Lopez-Perez introduced nothing to support his claim. He simply rests on his assertion that his father was born in California. Given that, aside from Lopez-Perez’s unsubstantiated assertion, the record supports the opposite conclusion, we find that Lopez-Perez has shown no plausible ground for relief and cannot show prejudice.
    
    The district court may rely on evidence that was inadmissible at Lopez-Perez’s removal proceeding before the IJ. Accordingly, the district court did not err in consulting the evidence in the record.
    For the foregoing reasons, we affirm.
    AFFIRMED.
