Hello. According to the Exit-Entry Administration Department of the Beijing Municipal Public Security Bureau, under normal circumstances, you can leave China on the day your visa expires. According to China Immigration Service Hotline 12367, if you entered China with a Chinese visa with a specified stay period, you can leave China on the day your visa expires, provided that you have not exceeded your stay period. Overstaying your permitted stay period is considered illegal residence in China, in which case you need to go to an exit-entry administration department to complete the stay and residence procedure before leaving. For more details, please call the China Immigration Service Hotline 12367 (+86-10-12367; foreign language services are available) for details. Thank you for your understanding and support!
