When you actually purchase foreign worker medical insurance, you would be required to send the workers for medical examination. It should be done prior to issuance of the work permit. However, you would be required to meet certain requirements for the medical check-up. The worker should be sent to Singapore registered doctor within two weeks of their arrival to Singapore.
The worker would be required to bring along the medical form in order to get the work permit issued. In event of the worker failing the medical examination, they would be sent home. The doctor would screen the workers for four different types of infectious diseases.
