That’s not exactly correct, iirc. It could be a crba or a us passport application and approval.
Also, iirc, if the parents neglect doing so, then he person can apply up to 21 years old, I believe.
Under today's law, the claim is viable for as long as a person lives. The law used to require US presence as a condition of citizenship retention. The law that covers Ted does have a citizenship retention requirement, but that has since been removed.
The citizenship retention under the 1952 statute was: present in the US before age 23; immediately following US presence, maintain five years of continuous presence. The five years of continuous presence is tallied only between the ages of 14 and 28.
The citizenship retention under the 1934 statute was: present in the US 5 years before the age of 21, the 5 years need not be a continuous period.
