Mother coming to live with wife and I. I am an only child and she is not eligible for any US benefits. Any experience with this?

I am glad I found this website, and want to know if anyone has ever had this happened to them. I am 28 and my mother is 75 about to be 76. My mother until recently was working full time at a factory that required a lot of her strength. She used to come home tired, and sometimes they made her work Saturdays. One day I went over to her apartment to have lunch there bc I have a key and she was there to my surprise. She told me she got laid off and she finally has that "weight" off her shoulder. Well I was a bit confused about the situation. She was crying a bit because she said she couldn't take this work anymore, and well that made me cry.

I told my mother that my wife and I have an open room that she can come stay with us and she accepted it. She will be moving in October with us and has started to sell a lot of things she doesn't need. My mom is undocumented and cannot receive any kind of government aid, and cannot even retire. We know she has a couple dollars saved in the bank but we also know that having an extra person in the house is going to increase some of our expenses. I don't mind the expenses being up but I just want to know how to deal with my mother back in my house. I love my mom but our house is not that big, and well I just hope we all get along together. My mom is not fluent in English that much, I am not sure how will she communicate with my wife, and I am not sure how will she cope with just being inside for most of the day?

We have researched about a CHEER center in our town, and is only 25 a month which is not bad. I guess instead of getting answer, I just want to know if there are any other only children that have had a situation like this happened to them. My mother said that if she seems that we are struggling financially, she will go back to Ecuador. I will fully support her but I know she won't be able to come back due to her overstaying her visa.

I cannot legally petition her until 2020, and I am not sure if they will ban her from coming back for 10 years in the USA . She will be 86-87 if she goes back. I keep stressing about this. Have any of you guys ever been the only child with a parent that is not legal in the USA? I know my mother says that she has a younger sister that could take care of her, and her nieces and nephews which I am glad, but I am not sure to what extent they will take care of her. I know that I would like to go to Ecuador twice a year if she moves back but financially speaking I am not sure it's going to happen, maybe once a year.
