<p>If you attend a california community college, and work to support yourself, and can prove you worked enough to support yourself, you probably can establish california residency. The key will be your grades at community college and columbia, your overall GPA. That will determine if you are admitted or not.</p>
<p>Since you’ve already enrolled at Columbia, I don’t think it will be possible for you to reapply as a freshman. You will need to attend community college and apply as a jr transfer.</p>
<p>Don’t take my word for any of this these are very complicated issues you need to research carefully before making any decisions.</p>
