Yes, I cannot say whether or not she is a citizen of the United States. I never thought to ask about such matter. However, another thing that is probably true is that she is probably wealthy enough to purchase citizenship in a variety of countries, depending on whichever way the wind is blowing at the moment, so I really don't see what that has to do with the price of tea in China. There are many U.S. citizens housed temporarily in jails and prisons and that type of thing, so I really don't see how the point of U.S. citizenship is such an all-encompassing category.
