Study abroad nursing. Which is more cost-effective, Britain, Australia or America?

1, simply comparing income, Britain is slightly higher than the United States, but the immigration policy is very strict. Although professional nursing also gives priority to the introduction of talents in short supply, it takes a long time to get a green card, and taxes have to be paid for several years, and the immigration policy in Britain has been continuously tightened in recent years.

2. America's immigration policy is looser than Britain's. If you can get a professional nursing qualification, it is easy to get a green card. However, I heard that this major in the United States is more difficult, with a high elimination rate (more than half) and very hard work.

3. It's not bad to be a teacher of Chinese as a foreign language abroad, and the income is very high.
