Definition: việc nhập quốc tịch phát sinh.
A more thorough explanation: Derivative naturalization refers to the process by which an individual automatically acquires citizenship of a country through the naturalization of a parent or spouse who is already a citizen of that country. This process is based on the principle that certain family members of a naturalized citizen can also become citizens by virtue of their relationship to the original naturalized citizen.
Example: The individual obtained derivative naturalization through their parent’s citizenship.
