首先我不知道：有沒有美加的MD回國內認證？
其次：doctoral in Medicine 等於 Bachelor in Medicine？

In USA and Canada, the M.D. degree is considered a professional degree and not an undergraduate degree. This means that individuals must have completed an undergraduate degree before applying to medical school to pursue the M.D. degree.
The reason why it may sometimes be referred to as an undergraduate program is that the first two years of medical school typically involve classroom-based learning, which is similar in structure to undergraduate education. However, the remaining two years involve clinical training and rotations, which are much more specialized and focused than typical undergraduate programs.
After completing medical school and receiving the M.D. degree, individuals must complete a residency program, which can range from 2-7 years depending on the specialty they choose. This is followed by certification exams and licensing requirements to practice medicine independently.
Overall, the M.D. degree is considered a doctorate-level degree in USA and Canada and is required to practice medicine as a licensed physician.
