US Immigration from Mexico

Hello I am trying to get my wife an I'd from the dmv in North Carolina. When she went with my mom to do it they told here there wasn't enough time left in her i-94 so they wouldn't give it to her. But somoone told me that if she brings her I-797 for the adjustment of status with her I-94 even if it's expired she should be able to get an I'd from the dmv can anyone tell me if that's true or not

I am an american citizen. My husband came here on a work visa about 4 years ago before we met. We got married this year and i want to do his papers to become a U.S. citizen. Where do i even start? I know nothing at all about this.

We have an oath ceremony at the EDGEWOOD THEATER OF PERFORMING ARTS in San Antonio and the entire thing seats 1,500 people. I'm not sure if that means we should except it to be filled or not. Has anyone been to a ceremony in a big venue? How long did the entire process take?

Thanks!

Has anyone gone though the green card process for the parents of the immigrant's parents once the immigrant gets citizenship? I understand the new citizen would have to file a 130 and then the parents would go to the consulate in Mexico and file the 485. I have a few questions.

-Does the new citizen filing the 130 affect the parents' availability to get a tourist visa that they regularly use?

-Does the parents filing the 485 affect their availability to get a tourist visa that they regularly use?

-Does getting a green card mean they have to commit to living in the US?

-How long does the 130 stay active until expiring?

We are waiting for our AOS interview and the I-94 date has long expired .. is there an issue with going to the interview while out of status. MY wife is a K1 visa holder and I am an U.S. citizen and we are married waiting on the AOS
