SB 554: Law enforcement: immigration enforcement.

This bill aims to amend California law enforcement regulations regarding immigration enforcement. It allows law enforcement agencies to provide information about a person's release date in response to requests from immigration authorities. The bill also permits limited exceptions to the prohibition on immigration enforcement, while requiring officials to cooperate only if it doesn't violate federal or state laws. Additionally, the bill prohibits local agencies from enacting ordinances that impose additional restrictions on law enforcement agencies related to immigration enforcement. The bill applies to all cities in California, including charter cities, and provides for reimbursement of costs mandated by the state if the commission determines the bill contains such costs.
