Some agencies require a statement from a doctor verifying infertility if an individual is adopting a healthy infant. When considering adopting a child from a Latin American country, parents may need to supply a doctor's statement of sound mental health as well. In Pennsylvania, you need to have notarized proof of child abuse and criminal clearance. Someone from the agency, most likely your social worker, will give you the forms you need fill out and where to send them to. After completing interviews and gathering all necessary documents, the social worker conducting the home study will write up a report.
Some agencies allow adoptive parents to read the home study report.
