I posted above what is required. It used to be BF required the fafsa to be filed, so citizen or qualified non-citizen. That requirement ended years ago and it was just the ‘graduate from a Florida school’ but now that has changed to ‘us citizen or citizen of a qualified country.’ If OP is a citizen of a qualified country, he has until Aug 31 to apply for BF (you have to apply by 8/31 of the year you graduate from hs, and it used to be you had to start using it within 1 year, so you could take a gap year but not more than that The requirements will not be the same for Florida BF or qualifying for Florida grants as for federal aid. That’s just Florida for you.
Those private florida schools are pretty expensive. Most of the financial aid packages consider that the student will also qualify for a Pell grant, BF, the Florida EASE grant (for residents going to a private school), SEOG, FL-SEOG and these will all stack with any grants the schools give.
