moving out of state with foster/adopt kids

In my case, I am in Maine and relocating to North Carolina. It is my understanding that once the TPR is complete and you have been identified as the adoptive resource, you may leave the state, if and only if, the only thing pending is finalization... meaning pretty much that there is only a slim to nothing chance that the adoption would NOT happen. My caseworker informed me that it is very common and can be done as long as we are close to finalization. I've never heard of it being done while there were still reunification efforts.
