same thing
I'm getting the same message too for my wife for the past 2 weeks! Nothing has changed . earlier it was, "on May 7th , we sent you a finger printing notice or something'...
She had gotten 4 finger printing notices and she had done hers in February, still the message was "On May 7th , we sent you a FP notice", when we called the INS center at that time, they said oh just ignore it and that our files are complete with both FPs and a lady said she sees in the computer that our case had already been assigned to an officer and its waiting to be picked up by him.
And it was sometime in May, and since then we are waiting and waiting and waiting......
