Hi, I currently have a Business (F) visa with multiple entries, with a 90-day duration of stay for each entry. I have just re-entered China for a new duration of stay, so I have about 80 days left for this valid stay. However, my visa will expire on May 4th. Do I have to leave China by May 4th because my visa will expire, or can I stay because I still have valid duration of stay remaining?

Best wishes,

Britta
