Taking placement tests at Miami Dade sounds like a great first step. I’m sure they have ESL placement, as they do here in CA. Getting started there doesn’t preclude relocating. If you’re really interested in the CA system, you could take a trip out here some time in the next year and check out the options in terms of locale and CC-to-CSU and CC-to-UC pathways. If you decided to make the leap, your college-level Miami Dade classes would transfer, and the remedial classes would count for placement. But you might as well get started where you are, and then if it’s going well, the “If it ain’t broke, don’t fix it” principle may well prevail!
