Hello,
I am from India and am supposed to travel to Hangzhou on business for 6 months. I came to know that the first business visa validity is for 1 month and then it can be extended locally in China. The problem is that my family (wife and 1 year son) needs to travel along with me and I was told by my company that my family needs to travel on tourist visa (which, like a business visa, has a validity of 1 month) and later get it extended in China... But the tourist visa can only be extended for another month (correct me if I am wrong) and they would either have to travel to Hongkong/outside China or back to India and reapply for another fresh tourist visa.
Is there any way my family can stay with me in Hangzhou for 6 month ? (My company cannot apply for a working visa for me...)
If not and they must apply for another fresh tourist visa then what is the best and fastest way for them.
Can they make a fresh tourist visa application immediately after the previous tourist visa expiry or is there any required wait time between 2 tourist visas?
Can my family make an such application in Hongkong or any other nearby city ? if yes, then how long can it take for such application ?
We all hold Indian passports.
Thanks a lot for your time and best regards,
Shakeel.
