Adds a new federal rule making certain noncitizens who are inadmissible under specified 8 U.S.C. 1182 provisions or deportable under specified 8 U.S.C. 1227 provisions subject to federal criminal penalties if they commit murder anywhere in the United States. First‑degree murder by such an alien is punishable by death or life imprisonment; second‑degree murder is punishable by a term of years or life.

The change creates a federal basis for prosecuting and punishing murders committed by covered noncitizens, applying the severe penalties available under federal murder law to those who meet the immigration-status criteria identified in the amendment.
