Yes, he is. But INS could check his citizenship application for truthfulness. Namely, his conduct in 1944/45 Budapest.

Miss Frances asks:Is George Soros a US citizen? Where does he live? Isn't it illegal for him to be influencing our elections?
Born in Hungary, Soros obtained U.S. citizenship in 1961. Yet he persists in describing himself as a "stateless" citizen of the world.
Which name did he apply for citizenship under? Schwartz? Soros? Melas? Is that public record? Can that be looked up?
Hmmm.... cryptic. What do you mean?
