China , youll be fine if you live in HK or Macau but be ready to pay a fortune to find a place to stay
Japan , forget it. You won't have a chance to pass it's citizen exam, only 20% of the people who applied manage to pass it.
Singapore, 80% is public housing so you're fine. Singapore is considered the US of Asia, everything will cost a fortune and youll have a slim chance to get a car as a camry will cost you like a 100k and you can only have it for 10 years.
Canada is all about either Vancouver or Toronto. Both run by chinese and arab people.
Australia is a really good place to stay.
Nowhere is safe but if you get a chance to get a place in the US specifically the west coast then it's probably the best place in earth to live in.
