US Immigration from Honduras

We are in the process of getting the I-130 filled out and the documents acquired when we noticed there are possible red flags.

First as I believe you only need the Birth Certificate of Petitioner and Birth Certificate of Beneficiary so we have my wife's and her mother's documents, but we realized that her mother's name is spelled wrong. One of her last names is missing a letter. We don't know when that happened. We have to wait until March to get back there just to fix it. How much of an issue is that really?

Second, apparently my Mother-in-law over-stayed a visa 20 years ago. Is there a form to submit along with the I-130 about that or do you just admit it when they ask last time you visited the US?

Lastly the father-in-law is concerned about the USCIS doing any research on him for some reason. I believe its an issue with multiple marriages or something. (This is why the daughter is applying for her mother and not him. He is a US Citizen.) So they want to fill out the form and just leave him off it completely. The docs we have show she isn't married, but the issue we have is the overstay. They reason for the overstay was she was visiting her husband. There is no official divorce papers which they wouldn't want to send anyways.

So how much of predicament are we in?

I'm helping my wife study for the civics test right now. Does anyone know if she can give just last names for the historical figures? For example, just "Wilson" instead of "Woodrow Wilson" or just "Hamilton" instead of "Alexander Hamilton"? Or maybe "President <Last Name>" would be acceptable if the answer is a president.

I imagine she can because the answers have the first names in parentheses, but I was wondering if anyone knows for sure. She struggles to remember first names sometimes, especially ones that are hard for a native Spanish speaker to say, like "Woodrow," and she gets the first names of our US senators mixed up sometimes.

Has anyone seen this before?

I am a US Citizen

On i130 application I indicated that we would be apply for the visa in the home country (not usa)

My husband is in the USA but we are applying for the I601A pardon...

Helping mother-in-law apply for US citizenship. However, it is asking for evidence regarding her grown adult children. Do I really need to submit this evidence?

* her daughter (my wife) is already a US citizen

* her other children are adults and they either are US citizens or live abroad

And if so, what evidence do they need? Getting copies of birth certificates may be a hassle.

I just received an appointment email for my husband's interview on Dec 8th. Our 2nd year anniversary is Dec 16th and I wanted our CR1 to turn to IR1 before the interview. Would it be worth it to call to see if I can change the appointment date to after or would be best to not change anything?
