Can I apply for a multiple entry visa valid for 12 months if I have Duly invitation from china?

Hello Angel! If you have obtained China entry permits before, it's possible that you will be granted with a 12-month multiple entry type. If it's the first time for you to apply, the possibility becomes less. As for the application fee, you can call the embassy at 5761036 (only available at 14:00 to 16:00 on business days) for consultation.
