Did I just make a terrible mistake..?

<p>I took a picture of my green card and submitted it as a .docx file. I submitted most of my apps by now, but apparently I submitted a picture that included only the front side of my green card. I got the sudden feeling that I was supposed to submit both sides.</p>

<p>Will this be fine? And if not, how do I send colleges a new document that includes a picture with both sides of my cards even after submitting my common app?</p>
