I want to know about Undocumented Students and can they take admission in California colleges then give me advice?

According to my view , Undocumented students mean they are neither U.S. citizen nor legal permanent resident and they do not have any green card or visa, or other legal documentation.

Theses type students can join college in California according to college eligibility.
Thses type of students can take admission in UC and most CSU campuses. For this they should talk with college/university representative to get right information.
