[n400wait]

I will get my naturalization certificate next week and I am planning to sponsor Green card for my parents. My mother is in US on B1 visa.
What all forms do I need to file please help ne.
I thought I-130 , I-485 , I-131 are enough but read in the forum that you need I-864, I am not sure what this is for. Can some one please help me and tell me what all documents I need to file.

Thanks for your help
