Dear Sir,
I have work permit and residence permit for China. My family (Wife and Son) wanted to visit China with Tourist VISA. I have following question:
1) Can they apply for extension for Turist VISA ?
2) Do, both (My wife & son) need to show minimum balance (i.e. 1.5 1.5 = 3 Lakh) in Bank account. My son is 4.5 yr old
3) Can they apply for dependent VISA from China?

Thanks !
