I want apply to hk work visa

Did you find a company in HK to employ you? If yes, you can get the relevant documents from there and then go back to your home country to apply for it.
The first step is to prepare the required documents: the application form, a passport-sized color photo, copy of your passport. Your employer needs to provide the application form, employment contract, business registration certificate, financial support of the company, documents about the detailed company background, and the detailed business plan of the company.
Next, submit the application to the embassy of PRC to apply for it.

Thank u very much sir
