How Long Does Interstate Compact Take?

My husband and I are interested in a sibling group of 4 from another state. We are not yet even started with our homestudy or classes. We hope to begin the classes in Oct. Do we have any shot at these kids? I don't want to get my hopes up if we have absolutely no chance. I know they recently became legally free for adoption, so they haven't been on for long. The children are Hispanic and DH is also. Would this be a helpful factor in the decision? I know there is a possibility they will be adopted by another family and I pray for that family and the kids. But if we had a shot, I would love to bring them home! Just trying to keep myself grounded. :confused: :confused: Shannon
