FOIA for I140 document - without receipt number

Anyone here in 2025 facing similar issue.

I am on L1A. Employer is not sharing I140 receipt number. I am just aware of my Priority date.
I summited FOIA request multiple times for I140 but I received same response as “NO records found” every time. I did attach following documents. [Not Notarized]

  1. Passport
  2. L1 797c document
  3. screenshot of priority date.

What document /step I am missing here ?. Please advice.

Do you know your A number? That’s usually the best way for USCIS to find your i140 record.

I don’t have A/Alien number as well.

Team, Please let me know your inputs to fetch i140 record in this situation.
