How Long Does Interstate Compact Take?

We're waiting on the child's social worker to select a family. I know each case is different but any ideas on how long this could take? We've put in for a sibling group in another state and it's been over 2 weeks since they "are reviewing homestudies".... and we haven't heard anything. We've been asked about another possible placement but I would like to wait to see what happens with this first set. Could this be weeks or months that we're talking about?
