US Immigration from Cambodia

My wife filed her N400 in September and her interview is scheduled for next week.

In December we changed addresses and she submitted a change of address to USCIS.

Should she have also filed some kind of amendment to her N400 to change her answers to "what is your address" and "what is your spouse's address"?

We didn't do that.

Is there anything she can/should do now? I'll make sure she has a copy of her driver's license and my driver's license showing we both reside at the new address, and copies of some bank statements and credit card statements with the new address. Is she likely to face any problems based on not having amended her answers, and is there anything we can/should do now? Thanks.

Is there a timeframe that we have to update the I864? If nothing changed with income and only filed taxes for the 2023 year. DQ Nov 2023, still waiting for interview date. Would it need to be updated or just do it either way?

Long story short.
I am US Citizen
I am living in Phnom Penh Cambodia and will be marrying a Cambodian woman later this year
She has 2 children 9 and 12

Once we get married, we would like to move to south America (Ecuador was first choice but with recent violence thinking Colombia)
We will get a retirement visa there (I am 50 and get disability income from my time in the US Marine Corps.)

Our plan is to get there, get situated, and then file for her CR-1 Visa to the US, and to remain there....together....until the visa is approved.

The question that I have is this.

If she is living in Colombia with me for a year or 18 months prior to the interview.

Will they allow that interview to occur where we are living (Colombia) and not where her home country is (Cambodia)?

Good luck(and congratulations) to everyone.

I am preparing to file the I-130 for my mother. I became a US citizen January 2023. Has everyone(or anyone) filed the I-130 online using the USCIS site or paper? I am filing on the USCIS site but there's something odd to me. During the application process it asks for an "A" number. Now that I am a US Citizen I don't need it correct? Even though I selected that I am a US Citizen, it seems like the site does not know it and keeps giving an error when I select "I don't have an A number". If I keep it selected, it will not allow me to submit the application. If I do not select it(but I don't put anything in the box) it will allow me to submit the application. Has anyone ran into that?

Got an email about 30 days after they submitted an inquiry. Got this as part of the response.

U.S. Citizenship and Immigration Services (USCIS) confirm your constituent s case is in line pending. We do not yet have established processing times for this form. In the interest of fairness to all applicants, USCIS generally processes petitions and applications in the order they are received and there are a number of pending cases.

My question is because it is at Potomac, there is no way to check processing times for this form online. Is "in line pending" just template speak to say they received the form? The only information I got from an agent at USCIS was that Potomac is currently working on 824s received in March 2023.
