The success rate when applying for a Hong Kong employment visa is relatively low. Even when the respective employment position is available, the government encourages companies to employ the local people first. Therefore, the application could be denied even if you have the right skills to encourage companies to source for human resources locally.
This reduces the unemployment rates, helps to grow the economy, and advances Hong Kong’s good name. Remember that even after getting the visa; your working eligibility is restricted to the employer who made the application. If you want to change the employment to a different company, an application for change of employment must be filed with the department of immigration.
