In Keirkhavash v. Holder, the Seventh Circuit evaluated the credibility of a petitioner who initially testified that she supported a group opposed to the Iranian government, but who in remanded proceedings testified that the claim was fabricated and she testified in support of it at the direction of her prior attorney. She then requested asylum on the basis that the Iranian government would harm her based on her fabricated statements in support of the opposition group. The Seventh Circuit affirmed the Immigration Judge's adverse credibility finding, stating that "[w]e reject any argument that an alien can obtain asylum or relief under the CAT by the very act of lying."
