Top Law Schools

As the title says, I'm by blood Native American (somewhere <30%) but was adopted and am white-passing. Obviously there's no CDIB and there really isn't a feasible way for me to figure out how to get one within the next half year. I do have other documentation from the government of my ancestry, but just no specifics that would get me a card.

I'm wondering if there is one/what the admissions boost would be for someone like me. I can't really write a diversity statement about being connected to a tribe or anything.
