I am adopting in Jamaica

OK. I have my home study scheduled for next week as well as filing my I600A and the I600 form at my local USCIS office next week. I did file the pre-adoption form to the Jamaican adoption agency. What I'm asking is what do I expect from here? What do I have to have before I can go to Jamaica to pick up the child? I have a child already and she is surely classified as an orphan there......no parents. What do I have to have before I can go? Can you tell that I'm anxious? Does anyone know app. what time frame I am looking at? I live in Florida. Thanks.
