US Immigration from Nigeria

I am filing out N400 online. My current spouse was married twice before our current marriage. In the previous marriage, he has three children. The form was asking if I have any children. I listed the names of the children of my spouse from his previous marriage and indicated that they are my stepchildren. On the list of documents, they are asking for the children's birth certificate and child support payment. I don't have any children from my current marriage. I don't understand why they are asking for their birth certificate and child support payments. On the form, do I say that I don't have any children. Please advise. Thanks.

Was wondering if anyone had any success in being granted an expedited interview in Lagos?

Hello. I was wondering if there was anyway to contact NVC to get resubmitted proof of relationship with household member reviewed. Or does the time start all over.

I ve looked everywhere but couldn t find a thread on this topic, so I thought to start one. If there s one before, kindly point me there. Thank you.
So here we go

Hi guys, Good morning y all. I am worried and I need someone to tell me it s okay. I went for my immigrant Visa interview yesterday, after all said and done my passport was returned to me with a white paper saying I should submit my Co-Sponsors IRS Tax Return Transcript for 2019 or 2020 which he s working on already and It ll take almost a week because he has to send it to Nigeria from the states. Is this something to be worried about? Is there a deadline to this?
