We have applied for N-400 and intend to apply for "Certificate of Citizenship" (N-600, I guess) for our 10 year daughter after we get our citizenship. I have to change her last name (to be my last name - currently, she has different last name which we chose at the time of her birth in other contry).
As I do not see any option in N-600 (like in N-400), how should I approach for this? Should I do it now far in advance before N-600 stage or during N-600? What kind of things I should be doing after last name changed too? Any suggestion and guide would be a great help.
