To Ellen

Thanks for responding, I have italian passport.. I don't have a plane ticket at all because I'm in HK now and planning to go to Shenzhen for some 10 days or more (from here to there i would take the bus or mtr). The reason why I want to make visa at the border is because it's faster, they usually give them in 1hr.. But the Shenzhen visa is only for 5days.. So what if I want to stay longer, is there some kind of entry-exit brearou in Shenzhen where they can extend visa?
