Sure no problem. We arrived on Saturday morning since that was the way the flights worked out and we wanted to not be rushed on anything and have as many days together as possible. As others have said, Guangzhou United Family medical clinic is not that busy so we went sunday afternoon to have her medical done with the plan of coming back monday at 12:30 to catch the shuttle for the vaccinations. You can do it in one day but be sure to arrive several hours before 12:00 for the medical exam so it can be completed and you can make the shuttle for the vaccinations the same day. The medical clinic that does the vaccinations is not open on sunday. Unless there is something that comes up in the medical, she will get the results the same day. She may have to return in the afternoon to pick them up so again, best to arrive early in the morning.
Document Drop off appointments start at 12:30 so worst case she can go and get the medical results in the morning this day, but that is pushing things a bit in case there is a problem. At the document drop off she will get a number and possibly a green sticker on her interview letter. Keep this as it has some bearing on the interview later. Not sure exactly what, but they split the 7:30 group up based on having this sticker or not. All of the interviews should be done by about 12:30 as this is when they start taking documents for the next day. After the interview, assuming she is approved, she will go to the EMS desk to pay for the visa delivery/pickup. Here you can designate if you will pick it up or have it delivered. Just because you don't live in one of the designated areas or Guangzhou doesn't mean you can't get it delivered. If she has a friend or family member in one of those places she can have it sent to them. The key is they must have the original of the EMS airbill (kind of like ups or fedex airbill). Without this no one can get the visa, even your wife. There is a website she can check to see when the EMS package is ready and there is a special desk at the post office for dealing with visa pickups. My wifes interview was on thursday and the visa was ready friday afternoon about 5:00 or so. The sheet says if you choose to have it delivered they will hold it for 7 days, but we learned they won't hold it for 7 minutes and it was on the way to her friends house friday evening. Her friend had gone out of town for the holiday so we tried to arrange to pick up the visa at the delivering post office, but they wouldn't release it since her friend now had the original EMS receipt
IMO a lot of the visa delivery time is related to when during the week you have your interview. I think they push to have them all out by friday afternoon so a monday/tuesday interview could take longer than a wednesday/thursday or thursday/friday interview. Just a guess, but it would be interesting to know from others if this is the case or not.
So long story longer, it may be ready the next day but you can't really count on that. You can have it delivered to someone you know in the designated areas as an alternative and not wait around for it, but if you choose this then the chances of picking it up should it be ready the next day are slim. If you really want to push, you can do the whole thing in 3 or 4 days
Day 1 - Arrive very early and go to GUF for medical for same day results. It takes a good hour to get to the east railway train station from the airport by taxi.
Day 2 - Go for Document drop off in the afternoon.
Day 3 - Go for interview in the morning and be done with the Salmon colored slip and the EMS receipt by 1:00 at the latest. If having it mailed then you're done.
Day 4 - Visa may be ready by this point, but no guarantees.
