Lanferman v. BIA, 576 F.3d 84 (2d Cir. Aug. 5, 2009) (court of appeals will not consider on petition for review of removal order whether guilty plea was obtained in violation of constitutional rights: "On appeal, Lanferman first argues that the agency erred in relying on his guilty plea, because that plea was obtained in violation of certain constitutional rights. This 'contention is nothing more than a collateral attack on his state conviction. Collateral attacks are not available in a ... petition challenging the BIA's removal decision.'"); citing Abimbola v. Ashcroft, 378 F.3d 173, 181 (2d Cir. 2004); see also Vargas v.
