I'm at the time where I'm beginning to apply for admission to many universities and scholarship programs. While studying some family trees recently, I discovered that I have significant Native American ancestry. All of the ancestors that are 100% Native American are at least 4 generations back.
My question:
Are there any guidelines/laws/legal precidents concerning what percentage of a race a person must be in order to claim to be a member of it for the purpose of affirmative action or similar programs?
