Hello. I'm french and I have a visa z which expires on 20th july. It's my second year in China and I never left the country. I would like to extend my visa without going to Hong Kong. I read that I can extend my visa in the police station for one more month. Is it really possible, even if my contract with my employee is over? And which documents I have to bring ? I just want stay a little bit more and travel in China before leaving.Because I really like this country !!!
