Hi!
I am an Indian passport holder traveling with family to Hong Kong. I plan on spending 2 days in Shenzhen. I would like to get a little info about the visa requirement for Shenzhen.
1. Can I apply for a Shenzhen visa in Hong Kong or can it only be applied for at the border?
2. Which is a faster/economical way to get to Shenzhen - ferry or train?
3. If I do take the ferry - is there an immigration check point to get the Shenzhen visa?

Thnx
