I have a question too.

I need to know if I should put the I-94w number instead of I-94.
In the form I-765 and I-821D, they ask for I-94 but what I have is I-94w, which I'm not sure it's the same thing. I would put some explanation on the last page of I-821D, but I-765 has no room for that.
Or should I just leave it blank and send a copy of my I-94w instead?
