Can you become a PSAT/NMSQT semifinalist/finalist if you're not an american citizen?

<p>I've read on the website that you have to be an american citizen or intend to be an american citizen to be in the running for the scholarship.
However, recently a friend told me that if you're not an american citizen you CAN'T be in the running, even if you score really well. Is that true?
Is there anyone or anyone you know who isn't an american citizen who became a semifinalist or finalist? What was you/their score and how long until citizenship?</p>
