H1B extension with I140 receipt notice

Hi Anil,

Could you please tell me if H1B extension after I140 approval can be filed based on only I140 receipt number or we need hard or soft copies of the approval notice?
My H1B 6 year cap expires in July and I140 is filed on 04/29/2020. Are there any chances of I140 approval coming before that ?

You need an approved i140 to file H1B 7th year Extension. Receipt copy is not enough.

Thanks for the reply.
If I see my I140 approval on USCIS website and there is a delay in getting hard copy of approval notice, can H1B be filed using the receipt number or is it mandatory to file h1 along with approved copy of i140 ?

You would need a copy of i140 approval.
