   MEMORANDUM

Mahde Shaban (“Shaban”) appeals the Board of Immigration Appeals’ summary affirmation of the Immigration Judge’s (IJ) credibility determination and decision denying him asylum and withholding of deportation, and ordering him to voluntarily depart.

We may reverse on a due process claim only if the proceeding was “so fundamentally unfair that the alien was prevented from reasonably presenting his case,” and it prejudiced his claim. Colmenar v. INS, 210 F.3d 967, 971 (9th Cir.2000); Cano-Merida v. INS, 311 F.3d 960, 965(9th Cir.2002). Although the IJ’s conduct of Shaban’s hearing was somewhat heavy-handed, he nevertheless allowed Shaban to fully present his case and issued a reasoned written opinion. See Antonio-Cruz v. INS, 147 F.3d 1129, 1131 (9th Cir.1998) (due process does not preclude an IJ from vigorously questioning the witness or conducting the “lion’s share of the cross examination”). Thus, the hearing, although not a model proceeding, did not rise to the level of a due process violation.

We must affirm an IJ’s credibility determination when it is supported by “substantial evidence,” and the IJ’s reasoning is not “fatally flawed.” Gui v. INS, 280 F.3d 1217, 1225 (9th Cir.2002). Thus, even if a reviewer could reasonably draw a different conclusion from the evidence, it does not mean the IJ’s conclusion was not supported by “substantial evidence.” See Rodriguez-Matamoros v. INS, 86 F.3d 158, 160 (9th Cir.1996); Singh-Kaur v. INS, 183 F.3d 1147, 1149-50 (9th Cir.1999).

Here, the IJ determined that Shaban’s United States religious instructor’s testimony revealed discrepancies in Shaban’s story that adversely affected Shaban’s credibility. See Gui, 280 F.3d at 1225 (adverse credibility findings must have a substantial nexus to the heart of the claim). Specifically, the instructor testified that Shaban never told him of his previous conversion and the instructor believed Shaban ignorant of Christianity’s basic tenets when they met. In addition, the IJ specifically detailed elements of Shaban’s demeanor that brought his credibility into doubt. Accordingly, we cannot determine that the IJ used fatally flawed reasoning when he found Shaban incredible.

PETITION DENIED.
