Hello, I am a student(holding an Indian passport) in Australia. Having some time in hand and wishing to travel i am contemplating of visiting HK, being aware that i do not need a visa to visit HK. However, having some uni friends in shenzhen, and if i do decide to vist them, would i need a visa to enter shenzhen, can i apply for the same in HK? is the visa time bound ? can i get multiple entry visa? or do i have to apply for it from Australia?
