The Hong Kong immigration department accepts applications from most nationalities all over the world except nationals of Afghanistan, Cambodia, Cuba, Laos, Korea, Nepal and Vietnam. The focus of the investment visa is to encourage people to set up businesses that can employ people, support the economy, and help Hong Kong to remain the best in the world.
If you can be allowed entry into Hong Kong, you can definitely apply for an investment visa. The most critical thing is meeting the threshold of applying for the visa. This means that you should have a good business plan to operate for about two years. Besides, the business plan should demonstrate how the company will be of help to the Hong Kong economy and have enough capital to meet all expenses for the first 6 months.
