Cotacted senator and filed official inquiry with Attorney Associ

You can see from my signature that my I140 was approved after 26 months which might be the record approval time for I140. Before that, my attorney initiated a couple of inquiry on I140, no response. I contacted the senator office and was told pending review. Later on my attorney filed another inquiry with immigration attorney association which is a very powerful association per my attorney. Days later, the attorney called me telling me the security review was cleared and my I140 will be adjudiated.

Good luck.
