I’m not trying to be insulting to anyone but just saying that schools are interested in diversity for a reason and just being able to check a box isn’t enough. My mother is Native American so I’m 1/2 by blood but never really had much tribal contact. My D brought up during the college admissions process if she should mark NA but I advised not to because she has absolutely no tribal contact. Now her mother is from South America, so my D was raised bi-lingual and has spent quite a bit of time in South America during the summers. She marked Hispanic and had life experiences to talk about in her applications.
So my point is not to get hung up on checking a box. Think about what you are bringing to the conversation. I did mention the scholarship thing because they do require documentation.
