Can mainlanders go to work in Hong Kong?

You can apply for a work visa as long as a company or organization is willing to formally hire you. The validity of the visa depends on the contract period of the company.

If it is a formal labor export, you can work in Hong Kong through labor export as long as you register with the labor export company and complete a series of inspections and procedures.

However, there are not many formal labor services exported from the mainland to Hong Kong, because the unemployment rate in Hong Kong is also relatively high, and there is a great demand for low-skilled jobs from local people. Unless you go there with a visa to visit relatives and then work as a so-called black worker, it is difficult to apply for a visa and find a job first. However, the wages of black workers are generally not high, which is actually illegal. Once reported or investigated, they will be deported and it will be difficult to apply for a visa in the future.
