Does it take one month to transfer social security from Shanghai to Shanghai?

No need. Official website, Shanghai Municipal Bureau of Human Resources and Social Security, inquired that according to the current social security policy, the household registration is Shanghai household registration, and those who participate in social security for employees in different places can apply to transfer their household registration back to Shanghai. The transfer procedure can be applied to the social security department in different places where you are currently insured, and the social security department in different places will issue a confirmation letter. After receiving the confirmation letter, return to the street community where the Shanghai household registration is located and submit the application, confirmation letter and other materials. The community will report the application materials to the Shanghai Municipal Bureau of Human Resources and Social Security, the municipal bureau and the social security department in different places for transfer, without additional payment. After the transfer is confirmed to be successful, the normal payment can be continued in Shanghai.
