If she is a citizen, she can start the process now.  It will likely take 1 to 2 years.

I recommend online filing for the I-130 petitions (2 total; 1 per parent): https://www.uscis.gov/i-130

At last at the end of our journey, my wife's both I751 and N400 has been approved (pending oath ceremony)

Only thing officer mentioned that he didn't like how names are short on those transcripts.  He wanted to see full name of the applicant( as it showed on form)on tax documents.Every officer is different but if you have those available, i would definitely take them. Nothing to lose . I was lucky, i only had for one year but he let me go outside and print more and bring back to him

Not an issue.  Technically, the I-751 must be adjudicated prior to an N-400 approval.  This sounds like a slow system update.  Congratulations.

As per website applicant needs to be here 30 month on 5 years. You are lucky. This is from uscis website 
 
Physical Presence Applicants are required to show that they were:
Physically present in the U.S. for thirty months within the five year period before applying, or (see legal basis) Physically present in the U.S. for eighteen months within the three year period before applying in the case of qualified spouses of U.S. citizens (see legal basis)  

I agree with you on this. Although in theory you can apply 90 days before but good idea to do bit later on to avoid any headache .I remember seeing another post where OP got denied because she applied 3 days early (mistook 90 days for 3 months)

You're right.  I remember seeing the issue a few times.  That is the reason I would always recommend filing a few days after the window opens.   

Yes, you should definitely go with your wife, and there's no problem taking your daughter too. If anything it probably helps to show good proof of the marriage.

Nothing you can do. USCIS will set it up how they see fit.

No, the point of doing the addresses etc is to reconcile meeting the physical presence and continuous residence requirements for naturalization. So putting jobs and addresses down prior to when you actually lived in the US is pointless and meaningless. It’s nothing to do with background checks.
 
As above. Pointless and confusing for the purposes of N400.  The addresses required are for the relevant period of residency in the US that count towards naturalization. We have seen countless posts of people who have filled in 3 years and been successful. Alerts do not stop you submitting the form and the interviewing officers know what is needed.

It is confusing but I don’t think you can only mention 3 years for education/ employment or addresses just because you are filling under 3 year rule . You will see an error because there will be a gap . I don’t know how that will be looking like when you review your application before submitting I just think that will show a red or at least a yellow alert
 
my understanding is you still can submit it with some errors but that can delay it so why? . Just do your best to provide what they need

Actually, this is a good question at least as far as the online forms are concerned. There is no reason that they can’t code it differently depending what the response is for part 1, given that they already have online forms that don’t ask irrelevant questions/ask different questions based on previous answers.
 
Everything is 3 years if you are applying based on 3 years marriage to USC.
 
 

For the 3 year rule, you don't need 5 years' information.

call them in late hours in US Time nor during US morning time

Hi.
 
I am a K1 visa holder and will be traveling from India to France (Vacation with my fiancé) and would be directly flying from France to US right after. I faced no issues regarding this while applying for a Schengen Visa and do not think theres any such restriction. 

I don't see any issues. The only travel that might cause an issue is to certain high-risk areas that raise security concerns.

you can look here as per your country and figure out what do you need to submit to NVC
