I-797 and I-94

[sm123]

Hi,
Please clarify my doubt on I-94...
I have a new H1 previously I was on L1-B blanket in US for 3 years..
now i want to get my H1 stamped. My I-797 has an I-94 attached at the bottom,
should I remove that while going for stamping ? will it cause any problem, if I have detached it from original I-797?
I have both the I-797 and its I-94, but wondering if detaching them would cause any problems..

I94 that's attached to the bottom has 2 sections - the left portion is for your records - the right portion must be turned in along with ur other existing I94 while u depart the US.

Thanks roline,
My doubt is I have removed the bottom portion of I-797 which has the I-94 (left and right portions) I have both the parts with me. Should it cause any problems during stamping ?
