You can take an online course at your current community college and pay for it out of pocket.
You can go to the new OOS school assuming you can pay for it.
You can submit your FAFSA to the OOS school any time during this term to get the federally funded loans…submitting it ONLY to the OOS school. But they won’t give you aid until you have enrolled as a student seeking a degree…
If you do NOT submit this new FAFSA to the old college, they won’t see it.
It sounds like you are amending a current FAFSA to submit to your new college. If so, you need to DELETE any other colleges on that form.
As noted by @sybbie719 do not try to be enrolled in both colleges concurrently towards a degree…this will definitely cause you issues.
I’m not sure why you would be continuing taking CC courses if you have decided to transfer to a four year university OOS. It’s very possible you are wasting your money…and the courses won’t transfer anyway.
