Find a job, interview, sign a contract, apply for permission, wait for approval, buy a plane ticket to fly to Singapore, go to the clinic for physical examination, get a work permit and start work. ...

If you can find your own job and handle the whole process, you don't need any money, just a few hundred dollars at most.

If you can't find a job, the agency will charge tens of thousands of agency fees.

If you have any questions, ask them.
