I have an indian passport. I was in china previously studying medicine for 5 years. Now I am back in india. My passport is valid upto 2013. And there are quite a few blank pages left in it so the passport shouldn't be a problem. I wanna go there and stay in Dalian at my indian friend's home for 2 months. He will be sending me the invite for coming and staying at his rented home. What documents do i need to show at the embassy? Since I wont be staying at a hotel and how much balance should i have in india to have a chinese visa? They will be giving only a one month tourist visa in india, is there any way to extend my visa in china after going there for atleast another month? How much money should i have in a bank account there to extend my visa?
