Hi, I'm Indian.how do get HK company sponsor visa..how long I stay to work there.pls answer

You should first prepare the required documents including the application form, a passport-style photo taken recently, copy of your passport, as well as proof of your work experience and education certificate.
Your company needs to provide these materials: the application form, the employment contract, copy of business registration certificate, proof of the company’s financial standing, documents about the company’s background, and detailed business plan.
Afterwards, submit the application to the embassy of PRC to apply for the work entry permit.

Once you get the work entry permit, you will be granted an initial stay of 24 months on employment condition in most cases.
