Scholarships for Undergrads who want to have high-impact careers?

Hi!

This is a bit unrelated to most posts. But I'm an international student at a US university, and I really want to have a high-impact career (really want to build something around alignment models for LLMs). But the rise in cost of attendance + family finances has really changed how hard it is for me to continue uni. 

I wanted to ask are there any undergrad scholarships for students? I know there was the undergrad scholarship by OpenPhil, but that's been discontinued and can't go down that road anymore I'm afraid. 

Any references or links to support would help a lot! Thanks!!
