U.S. Citizen Grandparent
If the USC parent has died, the USC parent must have met the physical presence requirement stated above at time of death. If the child’s USC parent does not meet the requirement, the child may rely on the physical presence of the child’s USC grandparent (at least 5 years, at least 2 years of which were after age 14), provided the grandparent meets the requirement as of the USC parent’s time of death.
Since the enactment of the Immigration and Nationality Act (INA) of 1952, Pub. L. 82-414 (June 27, 1952), Congress has provided for the naturalization of a child under age 18 upon petition by the U.S. citizen parent. See INA 322. The requirements varied with different amendments, but naturalization under this provision always required an application or petition by the parent; citizenship was not automatic.
