What are the procedures for transferring Shenzhen social security to Xiamen?

If you are sure that you will not return to work in Shenzhen, and you can continue to apply for insurance in Xiamen, you can apply to the resignation unit for inter-provincial transfer of social security (sealed by the unit), and then go through the transfer formalities with the original and photocopy of the social security card and ID card at the local social security office. For the specific process, the social security station has posted samples for reference. After completing the formalities, ask the social security salesman about the processing time (usually about 45 days). Wish you success!
