Kindly advise for visa holders

Here to remind foreign friends of some details about visa.

Firstly. L visa holders should pay attention to your expried date .as once i have a customer whose L visa is expired,and the PSB gave him a warn.
secondly ,L visa can be extended for twice, each time is for one month.

Thirdly, If you want to stay in china for a longer,you'd better apply for the F visa,and when you have a job here,you can convert your Fvisa to Z visa(residence permit) .

Hope you can have a good time in china!

I had no problem extending an "L" visa for 6 months.

is there any more details about visa extension?
