<p>Based on the information linked above, you can rightfully call yourself an American Indian. Calling yourself Native American, on the other hand, is a little more complicated. I suggest you start by looking at this Wikipedia article:</p>
<p>[Native</a> American name controversy - Wikipedia, the free encyclopedia](<a href=“Native American name controversy - Wikipedia”>Native American name controversy - Wikipedia)</p>
<p>IMHO, the term Native American refers to the native people of the 48 contiguous states, and may even extend to natives of Alaska, Hawaii, US territories in the South Pacific or Canada, but I have never seen it used in the context of the native people of Central and South America.</p>
