But neither the survival of your company or your well being might be viewed essential or of any benefit to Hong Kong.
Unlike the US or UK every Tom, Dick and Jane has a company or two in their backpockets... hardly makes you important or essential in the eyes of Immd.
Immigration did not "allow" you to open a company. One does not need any government consent to open a company in Hong Kong. You open a company because you want to use Hong Kong to do business.... you get a Visa because you need to stay in Hong Kong manage (or "join") that business.
