I'll be traveling to Hongkong for work. My wife plans to join me for about 20-22 days. Upon arriving in HK she can get the on arrival for 14 days. How do i manage to extend this to another 2 weeks? Is it possible to visit Macau or Shenzen from HK and get an on arrival in HK for 2 more weeks; if so can this be done on the same day itself or we need to stay for a day in Macau/Shenzen? The point is i don't want to apply for a normal visa if the on arrival serves the purpose of her staying for 20-22 days.
