The Board held that a conviction for unlawful possession of ammunition by a felon in violation of 18 U.S.C. § 922(g)(1) was categorically an aggravated felony. The Immigration and Nationality Act makes a conviction under “section 922(g)(1)... of title 18, United States Code (relating to firearms offenses)” an aggravated felony. The respondent had argued the parenthetical "relating to firearms offenses" limited the definition to firearms and thus excluded ammunition offenses. The Board rejected that argument. It noted that parentheticals have often been found to be merely descriptive and that the language of this particular parenthetical does not indicate Congress intended it to have a limiting effect.
