Adopting 8 year old - questions????

We are in the process of adopting an 8 year old little boy from the state(Texas). I have so many questions and hope that some of you with experience can help. This has truly been a loooong process. We were notified about a month ago that we were chosen for him and we finally received his package last Friday and reviewed it over the weekend. On Monday morning we advised our worker that we still wanted to proceed after reading his file. Our worker said the next step would be to set up a conference call with his worker and forster parent so that the "staffing" (questions can be answered) could take place. It is now late in the week and yet again we have not gotten a date and time set. It seems like the communication is poor (my worker constantly claims she has tried to get ahold of his worker and is waiting on a call back) and everything moves at a snails pace. We actually submitted interest in this little boy in September and it has taken this long to get where we are. I am really getting frustrated with the "system" and its non-motivated approach. I actually joked that we will probably get him by the time he is in High School. Has everyone else had this type of experience??? I have resorted to harassing my case worker by calling every day, if not twice a day in hopes that she will try to motivate the situation and all she says is "I am waiting on them to call". Anyhow - here are some of my other questions - what sort of questions would be ideal to ask the foster mother about the child prior to actually meeting the child?? I know that we have been told she will be at the "staffing" to answer any questions we may have and I am just trying to think of them all. How was visitation performed for those of you that have adopted older children? We have been told that we will have to make a visit to him one weekend and he will then visit us the next and within two weeks after that he will be permanently placed with us. How have some of you that have adopted an older child bonded with yours? I know this is long and I appreciate any input you may have! Rea
