Mr. Pjiang, I don't see original I-94 is necessay in the I-539 I

I used to read your I-539 表格是万金油. But when checking the I-539 Instruction(Page 5, Step2 General Requirements), it says '...the original or copy, front and back, of Form I-94....'. So it sounds that you are not necessarily required for the original copy. Right?

I did online application on Tue and sent the documents on Wed. Hopefully it'll be fine.
