URM for a bi-racial child

You can put both Hispanic and White and adcoms will look for the connection. You can add something else, if it applies. There is no “Well she marked Hispanic so we won’t evaluate based on her full application.”

But as said, making the connection count is more than just checking the box.

Sigh.

White for race. Hispanic for ethnicity.

India (scheduled castes and scheduled tribes get preferences in university admissions)
China (ethnic minorities get extra points on the gaokao for university admissions)

There are probably many others.

I don’t think China pursues it to such a fine art…

Are Chinese universities aiming for diversity in the student body, as many in the US seem to be?

They may want more authentic diversity.
