some of the questions in the n600 are optional for example

Your proof of U.S. citizenship

if you already have this they will approve your n-600 immediately and you wont wait that much.

and yes you are correct even if the questions are there some of them may not apply to your case.

no the certificate is not needed in every case, please find the requirement per each case in the link below.

https://travel.state.gov/content/travel/en/passports/requirements/citizenship-evidence.html

the full process is over here: https://travel.state.gov/content/travel/en/passports/apply-renew-passport/how-to-apply.html

yes they usually would be like 4 months in the national benefits center and then redirected to your local office. 

Takes about 8 to 9 months.

Then like I said grab the FAM(this is the department of state law book), go to the embassy and ask to speak with the American service's chief(had to do this thousand of times), and show him/her the law and explain your case.

yes that doesn't matter in this case, that was just a modification to the law prior to June 2017 if you were the only us citizen then you would only need 1 year of physical presence, that was eliminated and now is always 5, but in cases where one parent is an alien, please see that the article refers you in this case " If the individual cannot show that the U.S. citizen father meets the requirements of 309(a)", 

in this case you have 2 us citizen parents, the other us citizen parent has to comply with 309(a) that refers to acknowledge the child or legitimate and to acknowledge by written that he is gonna provide financial support for the child, this needs to be done in front of the consul.

I recommend you to go to the embassy with the law here is the foreing affairs manual that is the manul they use for guidance in all these matters.

https://fam.state.gov/fam/07fam/07fam1130.html#M1133_4_5_A

clearly states the following:

7 FAM 1133.4-5(A)  Birth Out of Wedlock to Two U.S. Citizen Parents

(CT:CON-748;   11-15-2017)

A child born abroad out of wedlock to a U.S. citizen father and a U.S. citizen mother acquires U.S. citizenship at birth if the U.S. citizen father first meets the four requirements of INA 309(a) after which, by the terms of 309(a), the provisions of INA 301(c) apply, and either U.S. citizen parent must establish that he/she has had a residence in the United States prior to the child's birth (see 7 FAM 1333.4-2 regarding residence).  If the individual cannot show that the U.S. citizen father meets the requirements of 309(a), but a claim can be made through the mother under INA 309(c) you should adjudicate the claim in accordance with 7 FAM 1133.4-5(C)(2) if the child was born before June 11, 2017, but if the child was born on or after June 12, 2017, please refer to AskPPTAdjudication@state.gov.

The residency laws are equal from out of wedlock or in wedlock what changes is the legitimation law

here is the nationality chart from children born out of wedlock.

https://www.uscis.gov/policymanual/HTML/PolicyManual-Appendix-Nationality2.html

look for "On or After June 12"

if you both are citizens, you don't need 5 years of physical presence, probably there is something missing here.

1. Child of Two U.S. Citizen Parents ^[7]

A child born outside of the United States and its outlying possessions acquires citizenship at birth if at the time of birth:

•Both of the child’s parents are U.S. citizens; and

•At least one parent had resided in the United States or one of its outlying possessions.

that "At least one parent had resided in the United States or one of its outlying possessions." means anytime in the US and any parent.

I would explain this one more time, the form of identification they are asking you is just to enter the building a green card or passport is fine, you already have the letter so do as the letter says, now if you need to provide residency in your jurisdiction a drivers license could be helpful but is not the only thing that you can show to prove this, you can show leases, mortgages, etc.

probably you will be asked for a form of identification but not for the interview, just to enter the building, a passport can be used for that purpose.

Certificate of naturalization, certificate of citizenship, US passport, all are proof of us citizenship to sponsor a family member you don't need a certificate. Like I said before this certificate is just for your first US Passport

The Department of State already has her as a us citizen, a simple file search can confirm this,  the certificate of citizenship is just to use for your first time passport in some complex cases when is hard to identify is she was a us citizen, in this case is unnecessary, even if you want something else to prove us citizenship, is better to get a passport card from the department of state and save it in a safe place just in case.

This message indicates nothing, my case was finished long time ago, and I still receive this message once in a while.

You can apply without the certificiate of citizenship. below are the requirements.Look for Us Citizenship through adoption.

https://travel.state.gov/content/travel/en/passports/requirements/citizenship-evidence.html

You can submit a consular report of birth abroad in any embassy around the world, but here is the trick doesn't matter where you do it, because anyways they will forward your application to applicant's birth country to check birth certificates and adjudicate that application. 

All n-600 are routed fist to a lockbox in phoenix to cash your payment, then from there they will get routed to the national benefits center in lee summit, missouri when they do the pre-screening of the application and then it will go to your local office after a few months. You cam check what office serves your are putting your zip code here.

https://www.uscis.gov/about-us/find-uscis-office/field-offices

Traveling abroad or not doesn't matter in an-600, remember that an n-600 is not requesting us citizenship for your children, if they comply with the requirements at any time before 18 years old then they automatically were citizens at that time, the Department of State will accept your Ir2 Visa(check for requirements in the url below, section born outside of the US)

https://travel.state.gov/content/travel/en/passports/requirements/citizenship-evidence.html

Repeated question, please delete.

They will send the N-600 to your local office, you would have to check processing times there, they usually take from 6-10 months, not everyone needs an interview that depends on the AO, but the oath is necessary for everyone older than 14 so they will probably have to go. Remember this is just a proof that they are citizens already you are not requesting citizenship for them, so no biometrics, if you comply with the requirements set by the congress then they will issue a certificate of citizenship.

Btw is usually cheaper to apply for a us passport only.

oh got it got it, so I think your minor case qualifies for an expedite request, look for this for your son.

https://www.uscis.gov/policymanual/HTML/PolicyManual-Volume1-PartA-Chapter12.html

and try to send a letter for them to process them at the same time.

hmm if you didnt file a i-130 for your son along with your husband, how is he moving to the US? yes all i-130 take the same time no matter who files unless you ask for expedite.

if you filed a i-130 for him he would be a us citizen in the moment he gets permanent residency and then you can apply for a us passport in that moment.

CRBA is for children that acquire citizenship at birth, that means you have to comply with the requirements before the child's birth, in this case a CRBA is not possible, it could be a few options for the child to get us citizenship anyways.

btw you dont need the CRBA if you still have the expired US passport, that is proof of us citizenship, so if you still have that with you, you can apply right now.

Check this out.
