Detain and Deport Illegal Aliens Who Commit Robbery Act

This bill would require U.S. immigration authorities to detain undocumented immigrants who are charged with, arrested for, convicted of, or admit to committing robbery offenses, rather than releasing them on bond. It amends immigration law to add robbery (defined by local jurisdiction) to the list of offenses triggering mandatory detention under specific inadmissibility categories. The Secretary of Homeland Security must issue a detainer to local authorities to hold these individuals if not already detained. This applies to undocumented immigrants already in immigration proceedings under certain inadmissibility grounds.
