The problem is that although Mr. Harris entered US naturalization process and became a naturalized US citizen, Mrs. Harris did not, and I'm guessing she got her green card only as long as she was married to Mr. Harris. So there is no evidence she matriculated thru our immigration process and subsequent naturalization.
And where in the 'law' did you find that obtaining a green card confers US citizenship, because it seems to me you can't pass something on that you never had.
Again, there are only 2 kinds of US citizenship; natural born, and naturalized.
I never said that a green card confers citizenship. Does it place the holder under the jurisdiction of the US? Yes.
