Creates new deportation and inadmissibility rules for noncitizens who incite, join, or commit violent acts during civil unrest, including assaults on law enforcement or military personnel and willful vandalism of public property. It bars those removed under the new rule from future admission and from many forms of immigration relief (including asylum, adjustment of status, and DACA), requires mandatory detention for covered offenses, and lets the Secretary of Homeland Security use expedited removal authority while certain federal, state, or local emergencies are in effect.

Takes effect on enactment and applies to offenses committed on or after that date.
