H1 stamping question

[candybee103]

I would still like to get some help from my previous question regarding the H1 stamping. My major concern now is my payrate is different that its stated on the H1 petition form(My payrate is lower than what it is). I heard that I need to bring the check stubs to the interview, is it a problem to get my passpoart stamped?

Besides, what other supporting documents that I need for the interview?

lease helllllp! Million thanks!
