Immigrate anywhere.

You can't answer this question correctly!

A, it is easy to immigrate, and find countries with immigrant types, such as the United States, Canada and Australia.

A non-immigrant country can hardly survive without relative immigration laws! For example, in Russia, the price of buying a house by foreigners is different from that of domestic people.

B, if the cost of living is not high, the general environment will be worse, like third world countries.

Countries with good environment, such as Switzerland, have high taxes and good welfare, so the environment is good, but the cost of living is high.
