Hiring manager at Oracle here- Oracle is very balkanized, different business units have different practices and policies, so I can only speak (unofficially) about the one I am part of.
Whenever I have openings for junior positions, I get flooded with resumes from men and women with degress at universities in China and India, and only a very small fraction from people educated entirely in the US. My personal speculation is that younger software engineers in the US would rather not work at a company that is perceived to be a dinosaur, and is definitely not as sexy as other FAANGs or startups. People who want to be H1-B sponsored have fewer options, and I think Oracle's name isn't as tainted in China or India.
Also, for the (unofficial) record, the women and those with H1-B visas (incl women with H1-B visas) on my team are paid the same as US born men on my team with similar experience.
