1. I think it will do, but the embassy have the final say to it.
2. a normal china visa process procedure takes 4 working days, and there is always express service for travellers under tight schedule such as 1-working day processing or 2-3 working days processing.
You just pay the normal fee for the normal service, and you have to pay additional fee for the express service in addition to the normal fee.
Hope I have clear it.
