A wise word of caution:
I went through the fast channel at Washington once with ID and NTO and the officer asked if I had a passport too? I replied yes and he asked to see it. Once handed over he promptly stamped it with his immigration stamp and then wrote in big blue pen NATO right across it.
Interestingly I have used the NTO in this way about 20 times and he was the only one to ask and I have never had a problem getting through.
