Dear members.,
Please advise about kids who are > 18
what is the procedure to the citizenship to them.
Over-18 would file their own N-400 if neither parent became a USC before they turned 18. If at least one parent naturalized before their 18th birthday then other facts must be considered to determine whether N-400 or N-600 would be appropriate.
1) what documents should it submit for kid citizenship @ interview time ?
2) should i present them @ interview time ?
3) They will some proof of citizenship status of kids after interview ?
4) should i ask about kids citinzenship and get some documents to kids citizenship ?
5) what documents should i need to apply passport for kids ?
6) I heard first parents should get citizenship, then kids automatically get citizenship (Just curiosity what is proof)?
7) First apply the Passport for kids and then apply for N-600 ? if there any documents for N-600?
Bring your kids birth certificates to the interview. They might not ask for them, as they're probably already in your immigration file, but have the b.certs with you in case the interviewer asks for them.
When at least one parent gets US citizenship, their green-card holder children will also automatically get citizenship provided the conditions of the Child Citizenship Act are satisfied (under 18, having custody etc.). What is not automatic is obtaining documentary proof of the children's citizenship, in the form of a US passport and/or N-600.
The supporting documents for the N-600 are essentially the same* as for the kids' first-time US passports -- your naturalization certificate, birth certificate to prove the parental relationship, marriage certificate if both parents are still married to each other (otherwise legal custody documents would be required for separated/divorced parents), plus documents to show that the children are still living with the naturalized parent, such as school records showing the children having the same address as the naturalized parent(s).
*however, if the N-600 is obtained first, it can be used as supporting evidence of the derivative citizenship when applying for the passport instead of the long list of documents I just mentioned. But for practical reasons, most parents will obtain the children's US passport first because it is quicker and cheaper -- the passport is usually issued in less than a month whereas N-600 takes 2-6 months.
