How long is the default duration for Visa F

Kelly, there is no standard duration for it. The consular officer just determines the stay duration according to your situation. So it's possible that you can get a stay duration of 30 days or more than 30 days. If what you get is shorter than 32 days, you can extend it at the local exit and entry administration seven days before the duration runs out and the process need seven working days or so. The fee is equal to apply for a single-entry F type, around CNY 168.
