OFWs in Malaysia can register for SSS by visiting the nearest Philippine Embassy or Consulate. You'll need to bring necessary documents like your valid ID, and proof of employment or income. You can also register online through the SSS website if you have an existing account. Make sure to check the official SSS site for any updates or specific requirements for OFWs. If you have further questions, contacting the SSS or the Philippine Embassy directly is advisable.
