I see, if you are scared of the mainland authorities, then you have no choice but to consider moving. I’ve never been scared from my extended stays in HK, Shenzhen and Macau, but I mind my own business, respect the laws of the land and have never run in to any problems. Freedom is subjective, a great example would be how I can get stopped and charged by police for drinking a beer in a park while BBQing or on the street in Toronto, but in China I am free to do so. There’s many other examples.
Back on topic, I know Canada has made it much easier for Hong Kongers to apply for PR via the post secondary route, if your sister has a solid education, that may be the way to go, not sure if this applies to Macau residents though. Canada is also fast tracking essential workers PR process, so if she has something to offer the country in the health care fields, maybe even finance fields then this might be the way to go.
You need to speak to a lawyer, a good one, either in Canada or in Macau.
Also, the value of your property may be something to look in to, if you want to make a permanent move with your sister, depending on how much your property is worth and how much liquidity you have, you/she could potentially invest in Canada and be granted a PR for your sister as an ‘investor’.
there’s many routes to take. Worst case scenario, if all fails, the refugee route could work as you mentioned ‘fear’ from the government and eroding ‘freedoms’. If I was an immigration officer I wouldn’t buy the fear aspect unless you were some political activist.
I’ll end this by saying the grass isn’t always greener on the other side. I wish you and your sister the best of luck no matter what you decide to do, and don’t forget you live in one of the best countries in the world, great food, entertainment, safety, quality of life and nature.
Please be well and stay safe my friend!
