Hello,
Does my fiance need my passport at the interview or a copy is ok?
Also, is a wedding reservation or arrangement needed to submit at the interview or does it matter or help at all?

Thanks

Copy is fine unless you will be in Guangzhou to be with your SO for the interview.

Wedding plans are OK, but don't set a solid date.
