Gertsenshteyn v. Mukasey, 544 F.3d 137 (2d Cir. Sept. 25, 2008) (federal conviction of violating and conspiring to violate 18 U.S.C. 2422(a), enticing individuals to travel in interstate or foreign commerce to engage in prostitution, did not constitute an aggravated felony under INA 101(a)(43)(K)(ii), 8 U.S.C. 1101(a)(43)(K)(ii) ("an offense that ... is described in section 2421, 2422 or 2423 of Title 18 ... if committed for commercial advantage"); BIA departed, with insufficient reason, from Second Circuit analysis long used to decide whether a noncitizen has been convicted of an aggravated felony; and it was unclear what result the BIA would reach under the proper framework).
