Hi I'm currently staying in Shenzhen for holiday to visit my gf who has internship in Shenzhen.
Due to the short notice she gave, I didn't manage to apply Visa in Singapore. So I came here as non-visa visitor and I would want to apply a visa for me to stay for 1 month and 3 weeks with her.
Q1: Where should I apply from and is it even possible for me to apply visa when I'm in Shenzhen now? Or by going to HK and come back to renew my 15days non-Visa is the only choice I have now? And if I do that will the custom officer grants me the 15 days renewal for sure?
Q2: If my gf going to HK with me but she only has a single trip visa in China, will she get the 15 days renewal too?
Please reply me asap as I really need help on it. Greatly appreciate it :)
