As long as your new employment unit continues to pay social insurance, the original social insurance can be transferred to your new employment.
The way is as follows:
Step 1: Print the payment voucher.
Before leaving Kunshan City, the insured person shall print the payment voucher for his/her participation in this city with his/her ID card, resignation certificate (stamped with the official seal of the unit), original and photocopy of social security card;
Step 2: Apply for transfer.
The insured person holds the "payment voucher" to the social security institution of the new employment place to apply for the continuation of the old-age insurance relationship.
The insured person only needs to complete the above two procedures, which is simply "take it away when leaving the job and resume employment". The old-age insurance relationship will be handled by the social security institutions of the new insured place and the original insured place, so that the insured person's insurance records can be connected.
