To be truly honest, if you were my kid, I would follow @NCalRent’s advice and give CSULB a try. I just offered you the CCC option. A CSU to UC transfer is possible, you just have to be diligent on trying to match your CSU courses to the required UC courses needed for transfer. There are no specific guidelines for the CSU-UC transfer other than what is posted on the UCSB website and through assist.org so if you are leaning towards this pathway, I would keep all syllabi from your CSU courses to help with the articulation.
As stated above, sociology will most likely require Grad school, so getting your Undergrad degree at CSULB and pursuing your Graduate degree at UCSB is an excellent alternative.
You chose CSULB for a reason so follow through and you may be pleasantly surprised. Best of luck with your decision.
