Depending on which country you study in, the countries where you study now are generally concentrated in the United States, Canada, Britain, Hong Kong, Australia, and of course a few countries such as France and Japan. It is difficult to apply for studying abroad. After all, there are few places for studying abroad in public schools and you have to get the admission notice from the school. If you are a student majoring in science and engineering, you can try to apply for a full scholarship. It is possible for Canadian masters to apply for full scholarships, and it is more difficult for American doctors to apply. Of course, getting a full scholarship is not only a matter of good undergraduate grades and good English, but also a matter of scientific research ability, which is reflected in publishing papers and attending international conferences. This is a long-term preparation process. But foreign doctors have good jobs, not just being professors.
