CA Assembly Bill AB-540 is a California law passed in 2001 which states that undocumented students who meet certain requirements can qualify to be exempt from nonresident tuition at California public colleges and universities (includes Community Colleges, CSUs and UCs). In 2014, Assembly Bill AB-2000 was passed, expanding the definition to allow additional flexibility for who can meet the requirements. In January of 2018, Senate Bill SB-68 went into effect, which further expands the criteria. This is very important because this exemption allows eligible undocumented students to pay the in-state tuition rate ($46/unit), rather than non-resident student tuition rate ($275/unit, effective Summer 2018 term).
