1. You must have a legally registered company in Macao to hire you, and then submit an application to the government to hire foreign workers. You can only work in Macao with the approval of the Macao government.
2. After the Macao government approves you, you go to your local entry-exit department, take the approval of the Macao government and the contract and relevant certificates for employing your company, and immediately apply for the Hong Kong and Macao Pass and endorse the business visa.
3. See if your company in Macao needs (in general): no criminal record to prove birth notarization, go to Macao to apply for health certificate, and go to Macao Labor Bureau to apply for blue card (foreign worker certificate), among which the certificate handled in Macao is necessary! The mainland depends on the needs of the enterprises that employ you.
4. Pack your bags, set off for Macao again, find a formal job and become a legal migrant worker in Macao.
Finally, if you know the ministries, you can apply for the Hong Kong and Macao Pass first, endorse the individual tour, and consult with the Macao Labor Bureau. Government officials in Macao will always answer your questions and teach you how to do it. Excellent service, milk tea or coffee is free, hehe.
I hope it works for you!
