It might be interesting to see his school transcripts from his prep school in Hawaii or Occidental College or Columbia University, to see if any of them listed him as a foreign student or gave him financial aid earmarked for foreign students only.
I’m sure he got plenty of aid because of his racial background. I doubt he needed any additional foreign aid. Doesn’t pretty much every university out there reserve a specific percentage of internal grants and scholarships for minority students only? I know mine did.
