Answers: C and D - There are two ways of acquiring U.S. citizenship at birth, and J.B. did not acquire U.S. citizenship at birth. Therefore, J.B. did not meet either of the two conditions for acquiring U.S. citizenship at birth. Specifically, J.B. was not born in the United States to U.S. citizen parents, and J.B. was not born overseas to U.S. citizen parents who previously lived in the United States for the required period of time. Any other conclusion is not supported by the information in the paragraph.
