helpufill, do you know this?

I submitted my gc application package 130+485 to local sf office but never got a receipt. It has been 1.5 months. No letters from them. Nothing. But we see the checks had been cashed just one week after I submitt my package. I called the national customer service number, they said the local office will not give a receipt.

If without receipt, I don't know the receipt number of my case. How Can I check the case status?

Do you know about this?

Thank u very much.
