What is Rose's citizenship status, who was born to an unmarried USC woman and later legitimated by marriage?

• A. USC because of her mother's U.S. residency prior to birth
• B. USC due to her father's legitimation after marriage
• C. Alien since she was born after 1940
• D. USC only if her parents were married at birth

Answer: (A)

The correct choice indicates that Rose has United States citizenship because her mother was a U.S. citizen at the time of her birth. Under U.S. immigration law, a child born to a U.S. citizen mother generally acquires U.S. citizenship at birth, even if the parents are unmarried. This principle is grounded in the idea that the citizenship of the mother is the determining factor in this situation.

While it is true that legitimation can impact citizenship status, for Rose, the key factor is her mother's citizenship prior to her birth. Therefore, Rose's citizenship is secured through her mother's status as a U.S. citizen.

Other options might mislead one into focusing on factors such as the father's legitimation or the marital status of the parents at the time of birth, which are not applicable here as the mother's citizenship is the primary factor for determining Rose's citizenship status.
