Currently, medical school admissions in the United States require a preparatory degree, which is equivalent to a four-year undergraduate degree in science and engineering. To apply for AMCAS after graduation, in addition to having a recognized academic qualification, you generally need to have a GPA of 3.0 or above. TOEFL, MCAT, letters of recommendation, etc. As mentioned above, if you go to a Chinese university, you basically have no chance, because you don’t have all the information collected, so you first have to find a way to get an undergraduate degree in science and engineering in the United States (most of them are direct pre-med courses now) ). Usually, language skills can be mastered at this stage. On the other hand, if you still can't master English after undergraduate/preparatory studies, there is no need to study medicine.
After applying and being admitted, you will start studying for four years of medical school. You will take the first medical qualification examination in your sophomore year, another one when you graduate, and then start a 3 to 5-year residency. Physician training is just like what "Grey's Anatomy" originally showed, where you go to the hospital to do an intern, and live in the dark like a pig or a dog. The training time and content vary depending on the chosen specialty. After the residency training, a final round of qualifying exams are taken, and then you can obtain the doctor's qualification. After being hired by a hospital, you usually have to undergo several more years of training, usually 3 to 5 years, before you can truly become a doctor who can practice medicine. In other words, it takes 14 to 18 years from the time you graduate from high school to truly become a doctor. Assuming you graduate from high school at the age of 18, you will be at least 32 years old by the time you finish suffering.
As for the hard work of studying medicine, it is hard in China, but extremely hard in the United States. Basically, those who study medicine are the elite of the elite. It is much more difficult than an MBA, and of course the rewards are also very high. If you are rich, you can at least have enough food and clothing in the United States.
The tuition for preparatory/undergraduate programs varies depending on the school. Medical school generally costs 15,000 to 30,000 US dollars per academic year. This is only self-funded and is the most basic. The actual cost is more than this. Much more, because self-payment only accounts for less than 15% of medical education, and hospitals, medical schools and the state bear the rest. Usually a medical student will have to bear a high educational loan before graduation, but it can be paid off quickly after working, which shows that the income of doctors in the United States is still very considerable.
As for the green card, it has nothing to do with what you study. It does not mean that you can apply for a green card or even naturalization after studying medicine. This is more complicated. However, it will naturally be easier if you graduate from a well-known medical school and are admitted to a well-known hospital.
If you are really confident, of course you can try, but you must be mentally prepared. Whether it is academic, financial, life, or other issues, studying medicine in the United States is more stressful than studying abroad. It is much larger, not to mention compared to studying medicine in China. As for ordinary universities, it is not on the same level at all. But in fact, China's current medical education is pretty good (compared to other majors). Good medical schools and hospitals will have many opportunities to go abroad in the future. Moreover, the income of Chinese doctors is pretty good. You can be a good doctor in China. You can also gain both fame and fortune. Compared with other ways of studying abroad, studying medicine in the United States is actually a very high-end and non-mainstream choice.
