How would they know if we left? - ICPC

And now it has been nearly a year and a half and still not one peep from the icpc. The social workers here have tried emailing the receiving county and state with no reply. My baby girl is worth this and so much more but how can anyone expect us to live for years away from our home, family, life for this long and it not be a giant disadvantage to the baby when we are finally free to go home and she is taken from the only place she's known for so long?! I wish someone would just pick up our file and at least BEGIN the process.
