Could my mom be shipped back to Australia?

Okay so, my mom came here in the 1980's. (To USA) And they said they needed paperwork that she hasn't been doing for about 14 - 15 years, and stuff like that due to a new goverment law. I'm really scared because I don't want my mom deported. :( And now she needs something updated or something.. and she needs to take a immagrant test to be a US citizen. And if she gets deported... am I allowed to go with her or no?
