USCIS FOIA Request for I-140 information (Sample G-639)

Hi,

Need some help. I have raised the FOIA request in online with G-639 and passport notarized and uploaded for my I-140 approval copy. The team was responding with 76 pages of complete I-140 documents. But I have not received I-140 approval copy. I called them and asked for the same they are saying that we have a complete set of your I-140 that is what they have shared to me that 76 page one.

Any suggestion or help how to get my I-140 approval copy, my employer is not sharing at all.
In that 76 pages I see one section Alien No: which is written with pen manually is that same number that is my I-140 Beneficiary/Alien number? which start with A- with 9 numbers.

Thank you!
