Here is some info about finances for international students at UCs http://admission.universityofcalifornia.edu/international/finances/index.html
"Most international students find it difficult to obtain financial assistance in the United States, particularly if no aid has been offered by an academic department or scholarship organization before arrival in the United States.
Also, it’s important to note that UC awards a very limited number of grants, loans and scholarships to international undergraduates. At some campuses, no assistance is available to international undergraduates."
Thanks @sophie9999 for your answer. I checked all the things on the FAFSA website, and I found out that I am not eligible to file for the FAFSA. I also am not a California resident. So, do not have to do anything for the March 2nd deadline? Or do I have to inform UC that I’m not eligible to apply for either of the two?
Your original application informed UC that you were an international applicant and thus not eligible for FAFSA or the Cal grant. You don’t need to contact them and you don’t need to worry about the deadline.
@Grativity No problem! You don’t have to meet any deadlines for need-based aid then. You don’t have to inform them of anything because they already know you are international.
