Resident permit for foreigner Valid until July 31 2016.

Ethan, it's hard to say. Sometimes it depends on your luck and the officer you meet with. If the person is not tough, you may not need to pay the fine. I advise you to get a 1-month tourist L type at the local PSB before your residence permit expires if you worry about problems. Or you can go to the aiport on July 31 and check in before 00:00 of August 1.

Thank you for your reply,
Does it change things If I am leaving China through Hong Kong (which Canadians do not require a tourist L type for).

Dear, I’m afraid it’s the same case. The most secure way is to go to the airport on July 31 and check in before 00:00 of August 1.

hi Ethan, usually if the duration of the overstay is less than 3 days. They will give you a written warning for first time offence. I once overstay for 24 hours and were given a written warning by the immigration and told not to repeat again (mine was multiple entry visa) and I'm free to go. By the time when I return to china the next trip everything was ok. There were no stop or check by the immigration. For your information a friend of my have the same issue and was also given a written warning. If the rules does change as the it was a 2 years ago. The fine is not more than RMB500 per day
