Which immigrant country has the best welfare, high wages and is more suitable for the development of young people?

Personally, I think it is Canada. In recent years, Canada has adjusted many immigration policies in order to attract foreign talents. On the whole, it looks as good as America and Britain. You can go to the intermediary for detailed consultation (it is not recommended that you go to the intermediary! )

Going to Australia is not recommended. There are too many people in China to have an advantage.
