I am planning to apply for N 600 for my kids. I live in East bay area, CA. I attended the interview at Sanfrancisco office.
I read the N600 intstructions. It says '' The application needs to send the local district office" . I seraced the internet I am confused with the addresses.
Can somebody help me to which address I have to send my application?

You should send it to the DO where you attended the interview,
