Performance bond is a deposit that you must work abroad according to the provisions of the overseas labor service contract and employment contract. The performance bond will be directly handed over by you to the operating company that sent you abroad, and the operating company will give you a receipt. After you return to China after fulfilling the labor service contract, the operating company will return the principal and interest of the performance bond (calculated according to the interest of current deposit during your labor service abroad) to you in full with the receipt you submitted. If you don't fulfill your obligations according to the contract, you have no right to ask for a refund of the deposit.
The service fee is the cost incurred by the operating company and your unit to provide organizational management services for your overseas labor services.
According to the national regulations, the performance bond can't exceed 20% of the total contract salary (excluding overtime pay, the same below) obtained during your working abroad.
To maintain a labor contract relationship with a domestic work unit, the service fee shall not exceed 25% of the total contract salary obtained during working abroad;
If you don't have a work unit or are divorced from the original unit during the dispatch period, the service fee can't exceed 12.5% of the total contract salary you get during your work abroad. You should carefully calculate the specific payment according to the contract.
Please note that you must ask for a receipt and keep it as the basis for asking for a refund in the future.
