This is the email I just got from our social worker:
Hi, Kristin. I am very happy to hear from you and glad we can help you with your adoption plans again! I pulled your file and it looks like your first home study was approved in March 2010. PA home studies can only be updated for 3 years from the approval date, and then you need to do a whole new one and not just an update. Because we have a file for you we can do that in just 1 visit to your home, and we can drop the fee from $1500 to $850 (plus mileage for the home visit - we are now located just outside of Coatesville).
That sounds crazy to me!!!!! What do you think?
