It is not what you think. Look for a job when you get to Hong Kong.
The normal application procedure is as follows: first, a company in Hong Kong wants you to fill out the Admission Scheme for Mainland Talents, and the company will help you submit the form to the Hong Kong Immigration Department. After the Immigration Bureau considers that it is qualified, it will issue a work visa; Your company issues you a work visa, and you take it to the mainland to apply for a Hong Kong and Macao pass.
That's not a pass, it's a Hong Kong and Macao pass.
Moreover, enterprises in Hong Kong do not recognize the academic qualifications of mainland universities.
So mainlanders working in Hong Kong is almost equivalent to a blank sheet of paper.
There is no competitiveness at all, and it is quite difficult to find a job.
You don't have a visa to go to Hong Kong. If you want to go to Hong Kong,
You can only apply for Hong Kong and Macao Pass at the Exit-Entry Administration Center of the Public Security Bureau where your account is located.
The cost of the work 100 yuan, signing a contract for 20 yuan once.
Then you can use this Hong Kong and Macao Pass to go to Hong Kong, but only for seven days.
Hong Kong and Macao Pass should be handled with ID card, household registration book and passport.
If you really want to work in Hong Kong,
I suggest you advance to a Hong Kong-funded company investing in the Mainland.
Try to climb up, and then find a chance to work in Hong Kong.
This is much more realistic.
