renewal of F Visa in China

Hey, Sudha. It is possible for you to renew it at the office of Exit-entry Administration Department in PRC. First, you need to submit a series of materials including your passport and its photocopy, registration form of temporary residence, application form, recent bareheaded color photo as well as an invitation letter issued by the inviting units. And then you may be required to accept a face-to-face interview to complete the process. I personally think you have a great chance to get it renewed. Good Luck!
