I just passed the citizenship exam, so I am US citizen now.
-You have to receive the US citizenship certificate to claim you are a formal US citizen.
My kid is under 18 years old, do I need to fill N-600 form for him to apply citizenship?
-Your kid can either files N-600 or directly applys for his US passport to claim his US citizenship after you receive your US citizen certificate.
It costs $600.
