Hi @Ishaandham – welcome! And congratulations on your Green Card.
I’m not an expert in California Community Colleges, but from what I’ve read on this forum, California has a great system that helps students successfully transfer into four-year colleges. Without knowing your GPA it’s impossible to know whether to advise that you first go to CC or to try to go directly into a UC.
Perhaps consult the California College forum or repost your question there. This forum has a lot of people from California who can help you.
Be sure to list your GPA when you repost.
