What should I do if I change social security in my work city?

You can transfer social security to your work city.

When migrant workers from different regions leave their places of employment, they should apply to the Social Security Bureau for proof of payment of old-age insurance with their ID cards. After they join the new employment unit and pay the social insurance premium, the insured or the employer will apply to the social security bureau of the new employment place for the transfer of the old-age insurance relationship with the old-age insurance payment voucher. After successful processing, the social security of the two places will be combined to calculate the payment time and accumulated payment amount.
