Deferred Action for Childhood Arrivals is a federal program through Department of Homeland Security which gave eligible applicants a two year renewable work permit to lawfully work in the United States and protection from deportation. As of 2017, it is currently under review under the Trump administration. However, in the state of California, DACA has nothing to do with financial aid or attending college.
In the state of California, an undocumented student who is eligible for and completes and affidavit form for AB 540/2000/68 can apply for all state financial aid by either completing the CA Dream Act application online by the March 2nd deadline for the upcoming academic year or by completing the California Promise Grant application (formerly known as Board of Governors Fee Waiver).
The CA Dream Act is a financial aid application similar to the FAFSA for students in California who meet AB 540/AB 2000/ SB 68 criteria. This allows eligible students to apply for state financial aid only (not federal) such as Cal Grant. DACA has nothing to do with state financial aid.
