Make Tourist Visa In Hk Or China

Hi

After posting here "Visa run Penang", I got nice answer explaining that Penang will probably not give Visa to people who already did extension at local immigration.

For information on last 12 months, I did 3 tourist visa (2 months) and extented 2 of them to 3 months. And I'm actually on an extension.

So, you advised me going to KL. But as going to KL by plane is very expensive (from Koh Samui), now I'm looking for going to BKK by bus, then to HK or China to visit and make my visa.

So, do you know my chance of getting a single entry 2 months tourist visa in HK or China (Canton, Shangai) ?

Thanks !
