US Immigration from Kenya

Ok, I'm sure this has been addressed here...but it's been years since I've been on and I need help please.

Went thru the K1 Visa Process...got married...for the most part everything is amazing. My current wife had a child prior to us meeting and that child came to the US on the K1 visa with her. He's a great guy (despite some academic laziness).

Both wife and her son, became permanent residents and then eventually my wife became a citizen. From everything I can tell, her son automatically became a citizen too.

But this is where I need help!! PLEASE!!! How does my son get paperwork to prove he's a citizen?? His last name is different from my wife's last name bcuz from my understanding that's how they do it in Kenya...his last name is my wife's middle name...We want to get him a US passport? Plus for insurances purposes I'm being asked to provide documents to prove his citizenship, I don't have any.....

Plus his school records are messed up becuz we registered him in school when he first got here with her last name, but that's not truly his last name on any legal document, so once we have documents proving he's a US citizen, we want to change his name to match ours.....and then get his school records to match that.

URGH!!! Please HELP!!

It took us three years from applying IR-1 till got the visa, then 3 years permanent resident , N-400 took one whole year to the interview and now 8 weeks or even more for the passport.

Does anyone know the typical time frame that NVC responds to your Expedited Interview request email?

What qualifies one to get an expedited appointments? I applied twice in Nairobi and i was denied yet i work in a hospital.

Hi VJ members, I naturalized American on November 20, my youngest daughter will turn 18 on December 24th, about a month since naturalization, they said if one of the parents naturalized American before his child turns 18, the child automatically acquires citizenship. Does this apply on my daughter?
