Hi, I am a Bruneian Passport Holder and I am currently in PRC (Nanning) on a Youth Exchange Program for 8 weeks. I have a VISA to China (Single Entry) which is valid until the 30th December 2009. However, I will be leaving Nanning, China, on the 18th of December via HK. As I will have to stay the night in HK, is there any problems if I choose to go to Macau (via Ferry) and spend a couple of nights there BEFORE returning back to HK airport and flying back to Brunei.
