visa issue

Dear, the S2 type can possibly be extended before it expires and it’s possible for your wife to get an extension of 60 days. It costs CNY168.

Thanks for your reply, please explain the process of how i can do that? ( Where to go and if there is a form to fill in and so forth).

thanks

You should apply for an extension at the exit and entry administration of the local PSB. Your wife should provide the following required documents: her passport, the application form attached with a recent passport-style color photo, valid temporary accommodation registration form, your residence permit, the marriage certificate as well as other documents that the exit and entry administration consider it necessary to hand in.

please explain the meaning of " exit and entry administation of the local PSB'" . I don't understand.

Dear, it is an authorized department of Chinese public security bureau and it is mainly in charge of the relevant exit and entry things.
