US HB7664

Authorizes DHS Secretary to enter written agreements with states allowing licensed state attorneys to represent DHS in immigration removal proceedings at the state's expense, with state employees subject to federal direction and supervision

State attorneys participating must have knowledge of federal immigration law, receive adequate training, and have no independent prosecutorial or policymaking discretion

Applies to removal proceedings under Section 238 for aliens in correctional facilities, or Section 240 proceedings where charges are based on state law violations or where state law violations affect immigration relief eligibility

Significantly expands the definition of "aggravated felony" to include any felony or offense punishable by more than 1 year imprisonment, adds new covered offenses (straw purchasing of firearms, carjacking, war crimes, torture, genocide), and broadens drug and theft offense categories

Makes aggravated felony convictions grounds for inadmissibility and automatically considers aggravated felony convictions as "particularly serious crimes" for asylum and withholding of removal purposes, with changes applying retroactively to offenses committed before enactment
