<p>Do we have to prove our US citizenship to Harvard if we were born in another country? They haven't asked for anything from me concerning this, but the idea just popped into my mind that I might have to send in photocopies of my US Passport. Anyone?</p>
<p>On the commonapp there is a "dual US citizen check box" they also require the secondcountry ofcitizenship!</p>
<p>I believe that schools verify things like this directly through the USCIS.</p>
