Hi

I am working in hkg for last 5 years and have a multi-entry china visa. My son (10 years) would be visiting me from india (i am divorced and he doesnt stay withe me)and i would like to take him to windows of the world and spendid china in shenzhen. Would it be possible to get a visa on arrival for him at luohu border. Can i apply in Hong kong as well? I am apprehensive about my ex-wife applying in India as they require lots of financial documents in original which i am not willing to share. Please advise.
