My lawyer told me the same thing,But I couldn't wait.

I called USCIS ten times, one CSR told me my case assign to IO XX days ago, I put 2 service request throught CSR.
I went to infopass twice.
I didn't get any infopass on my first visit in Feb.
Today I went to Infopass, they told me I am green.
I think you are in good shape, since you hadLUD on I-140 as I had In July.
You had LUD on I-485 in march as I had in March.
Good luck.
