I called too, got exact same answer

case not yet assigned to immigration officer, 4/30 is the new deadline, be patient.

I am EB2 PD 05/2001, RD 12/2006. Sigh.

Usually when I call POJ I need to hold for 15-20 minutes. This time someone answered almost right away. I have the same feeling that they are customer service, not immigration office.
