Can H1B transfer happen without i-797 Copy ?

[rahuljainusa007]

Hi

I haven't received the copy of my H1B approval (i-797) from my employer ( my employer maintains that it hasn't got it from USCIS), but my H1B transfer to this employer has been approved by USCIS, as I can trak it online. My question is , "Can a company get my H1B transfer just on the basis of the receipt number or copy of the receipt notice ?"

Thanks
Rahul
