<p>Ethnicity is a complex concept, but in admissions, it is useful to help them consider the diversity of their campus. If you identify with the Turkish culture and you have a grandparent that is Turkish, then that is not untruthful. It may or may not make a difference in college admissions, but what could make a difference is if you are the first in your family to attend or potentially graduate from college. In some situations where a grandparent migrates to America, they start out as a lower paid laborer, can maybe get their children through high school and some add’l job training, so the next wave of births (your generation) could be the first to be able to realistically attend and graduate from college.</p>
