I thought this might be the best place to ask. I'll just jump straight into it.
These questions pertain to current day as well as when the UK had control over Hong Kong.
When the UK had control of Hong Kong, where they considered citizens of the UK? Could they freely move from Hong Kong to the UK and back?
This question assumes that the first is true... Sort of...
If a native Hong Konger moved to the UK or another country of the commonwealth/realms/empire, and then the UK gave up control to China, would the Hong Konger still be considered a citizen of the UK?
3 . I have a police man friend that moved to Ontario Canada with his parents as a child before the UK gave control to China. He's now a citizen of Canada and part of the Niagara Regional Police.
If he wanted to go back to his home country today, what problems would he face, if any? Would he still be considered part of the country as it exists today? Or would he be a UK citizen, or otherwise?
Any other information regarding Honk Kong, or just tid bits of history of Hong Kong and it's relation to the UK and the Empire are welcome.
Hong Kong people weren't really considered citizens of the UK, they could get a subclass of British passport called a British National (overseas) passport which everyone referred to as a BNO, but it didn't give them the right to reside in the UK. So they were also called 'doorstoppers'.
A lot of countries had capped immigration programs, pretty similar to what's in place now so the procedure to emigrate was pretty similar to what it is today.
People who want to return are able to if they had the classification of permanent resident of HK before, that status isn't canceled by taking citizenship of another country.
If he wanted to go back to his home country today…
Unfortunately we have a 20-year rule in place, so we can't address anything after 1995. Could you please edit your original post to remove these sub-questions? Otherwise the whole post may wnd up being removed.
