Martinez v. Mukasey, 519 F.3d 532 (5th Cir. Mar. 11, 2008) (noncitizens who adjust post-entry to LPR status are not disqualified from eligibility for a waiver of inadmissibility under INA 212(h)'s plain language ["No waiver shall be granted under this subsection in the case of an alien who has previously been admitted to the United States as an alien lawfully admitted for permanent residence if ... since the date of such admission the alien has been convicted of an aggravated felony"], and the definition of "admission" ["The terms admission and admitted mean, with respect to an alien, the lawful entry of the alien into the United States after inspection and authorization by an immigration officer"-- INA 101(a)(13)(A), 8 U.S.C. 1101(a)(13)(A)(emphasis added)], which demonstrate unambiguously Congress' intent not to bar them from seeking a waiver of inadmissibility, so no Chevron deference is required to the BIA's interpretation of the statute), following Waggoner v. Gonzales, 488 F.3d 632, 636 (5th Cir. 2007), and rejecting an analogy to Matter of Rosas-Ramirez, 22 I. & N. Dec. 616, 617-619 (BIA 1999) (en banc) (noncitizen who had entered without inspection, and was later adjusted to LPR status, was considered "admitted," and thus subject to removal proceedings under INA 237(a)(2)(A)(iii), 8 U.S.C. 1227(a)(2)(A)(iii), based on an aggravated-felony conviction occurring after adjustment).
