Ghani v. Holder, 557 F.3d 836 (7th Cir. Mar. 9, 2009) ("As a threshold matter, we note that Mr. Ghani did not raise this claim before the BIA; therefore, the issue is waived. See Hamdan v. Gonzales, 425 F.3d 1051, 1058 n. 14 (7th Cir.2005) (arguments not raised to the BIA are waived for failure to exhaust administrative remedies).").
