This designation is needed for multiple USCIS forms. Please pick all the races that apply to you; it is best to pick all races that you have definitive knowledge of from you ancestry.
Note: Please pick the same race you may have previously used is USCIS/DHS forms.
If you are picking American Indian or Pacific islander please make sure your choices are correct since these races largely apply to US populations, there are some exceptions of course but we are providing this information for your benefit.
