Why prepare for a fight against a cat, yet in reality you will be facing a lion??
My sentiments still stand. There's more to this story. I'm sure lawyers et al have been visited/ consulted during this time. So, there's a specific reason why she hasn't naturalized all this while, even when the husband did. So, unless OP lays it all bare, our "positive/ what they wanna hear" replies are just two puffs of warm air in the polar region. Additionally, N400 preparations are offered in multiple languages. Someone had already asked if OP mom can speak.
We should stop selling fake positives to people. People come here for advise to fix a situation. Some lay it all out, others do 50/50 and we have to connect the dots ourselves. So, when something doesn't make sense, we have the right to question because at the end of the day, our positive replies are useless if there's more to the story. Couldn't she have naturalized at 65 using our "postive" replies? Why didn't she? Heck, she can even take our positive replies and go try and naturalize today. The results would be the same. Then OP will say we in VJ lied to them.
VJ isn't about comforting people. We endeavor to help and it's easier to help when all is laid bare.
I'll be Mike-E-ing at this point.
