GC Parents name change (N-400) and US kids name change procedures?

[kay_jay 0]

We are family of 4 (2 adults and 2 kids). My wife & I had green card for > 5 years and submitted N-400 application with last name change last week. [Our 2 kids who are born in the US (US citizens).]
1a. What are the procedure involved in the name change after submitting N-400?
1b. If I book any international travel for next year, which name should be given? 
1c. How easy is to transfer our name change in all the legal documents: SSN, DMV, job place, banks, tax, 401k account, global entry, travel, utilities etc etc.
1d. Is there a easy way to change our name in all these places?
1e. Is there a checklist where we can track our progress in change of names in all the legal documents?

 

2. As mentioned earlier, Our 2 kids who are born in the US (US citizens), will have to changes their last names once our names are changed. 
2a. We need to update their name changes in all the legal documents as well. What is the procedure to do this? When do we start the process? Where do we get all these information?
2b. What happens to their birth certificates?
2c. We just recently renewed both their passports. What is the process to change their names in the passports?

 

3. Is it a wise decision to book our international travel for next year with current or new last names?

Together how long is this entire process takes?

BTW, we are based out of San Francisco, CA (San Mateo County). 

Can we do legal name change through N-400?

If not, what is the procedure and cost involved?

You and your wife can do a name change during the N400 process. The kids you will need to petition the courts to get it legally changed.

Just curious, but can a name change request during naturalization slow down the process a bit because I assume they basically petition the courts on your behalf?

Yes it can as some places do judicial ceremonies less often.

Good to know. I'm primarily known by an alias I've had for about 14 years that's no where near the same as my legal first or middle name, so I was planning on having it changed when I file for naturalization. Cheers.

I saw that name change will not be possible for San Francisco and San Jose residents through N-400, it must be done separately for SF & SJ residents according the sticky post: 

 

Is that now changed?
