1. if you have enough money to get through 4 year college for the next 2~3 yrs, apply to state schools in Cali. I'm sure you'll get accepted with 4.0. Or apply to New York public colleges as schools in Cali and NY are most understanding towards undocumented. Perhaps you can work through college working part time like most of us.

2. if you decide to go to Korea, you'd most likely want to serve 2 years in army before going on to senior college. Expect about 4~5 years until you graduate from college as some credits might not transfer.

P.S you can't fill out FAFSA because you're not eligible to be granted any state fund. on transfer applications, you have to fill out paper applications (most likely). Fill out "others" and then write "undocumented" if they ask you for your legal status.
