Hi there I was finally contacted back by my state by a worker the worker that is going to do the home study she called me yesterday and told me that she was sending out a big packet of paperwork but not to get too overwhelmed and try to work through it as fast as I can and get it back to her cuz somebody please enlighten me and tell me what will be in this paperwork I'm sure it will be it a lot of different questions what I am wondering about is a financial part mainly do they run a credit check? Also wondering what I will have to prove as far as my financial to them? I make enough money to be able to survive myself just fine none of my utilities or anything has ever been turned off. I lived in my address for seven years I'm wondering how much extra money I will have to be able to have those to be able to adopt a child the child that I am adopting gets other assistance as well from the government SS??? Oh and I guess one more thing how much documentation will I have to give them as far as my medical history do I have to go back tell when I was a child? Also I am wondering are they going to want me to give them an accurate record of my whole life as far as where I lived and how long I live there and what not I am new to all this sorry I have so many questions???
