Want to go to Canada or Australia to study for a doctorate and then immigrate, is it reliable?

It depends on whether your present life has anything to do with your job.

After immigrating to Canada, everything started from scratch, and language and work required hard work. More importantly, the changes in living environment, such as diet, entertainment, communication and law, are completely different from those in China, and many people are not suitable for returning to China for this reason.

Of course, there are also lucky people who find good jobs soon after landing, adapt to the environment in Canada and live happily.

The problem is that it is difficult to immigrate to Canada now.
