When filing for naturalization, if I am the father of a child not yet born during the time of application, what is it that I put for part 10?

If the child is not yet born, you would not put down any information on the child in the N-400 application. If the child is born by the time of your interview, you can bring the original and copy of the child’s birth certificate and give it to the naturalization examiner.Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.
