Where to apply EA for African?

I’m trying to decipher where I can get the most “bang for my buck.” My college list currently includes Harvard, Stanford, Yale, Princeton, and Amherst. I think, being an international, I might get deferred to RD at a few of those. I’m really set on Harvard.

I want to know if you guys know how Harvard and the other universities listed above consider Internationals in the EA round? Any African accepted EA?

PS: Any African out there applying to the Ivy League? Would love to have someone I can go through the process with.

International Student (not African) but in International school in WAfrica applying to a few of those
