California SB 54 stops local law enforcement from telling Immigration and Customs when they will release certain individuals and from facilitating their transfer unless the individuals have committed certain crimes.
AB 450 restricts private employer’s ability to cooperate with federal immigration officials.
AB 103 allows the state to review federal immigrant detention of immigrants inside the state.
