Rosalie Ntumba-Kadiombo, a native and citizen of the Democratic Republic of the Congo, petitions this court to review the decision of the Board of Immigration Appeals (BIA) denying her application for asylum. The immigration judge (IJ) denied relief based upon a finding that her testimony was not credible, and the BIA affirmed the IJ’s decision. Ntumba-Kadiombo argues that she is a refugee for purposes of obtaining asylum and that her testimony was credible.
Ntumba-Kadiombo’s appeal is subject to dismissal for failure to comply with the rules requiring citations to the record and relevant legal authority. See Moore v. FDIC, 993 F.2d 106, 107 (5th Cir.1993); Fed. R.App. P. 28(a); 5th Cir. Rule 28.2.3. Moreover, assuming arguendo that her arguments were briefed adequately, we would not “substitute our judgment for that of the BIA or IJ with respect to the credibility of witnesses or ultimate factual findings based on credibility determinations.” Chun v. INS, 40 F.3d 76, 78 (5th Cir.1994).
The petition for review is DENIED.
