<p>You are not required to check either ethnicity (Hispanic) or race (white, NA, etc.); you can mark one, both or neither.</p>
<p>Checking white will not change your status as Hispanic, as Hispanics can be and are of any race(s). Many South Americans are white and many are mestizo.</p>
<p>Just to clarify, you are first gen to college (anywhere) right? First gen to the US does not make a difference for college admissions purposes.</p>
