SAMPLE: 醫學院本科畢業的自稱MD可以理解?

"If they pass the US board certification, I think that is more reasonable." ----agree， but not that simple. here is q/a from AMA website:

I am an IMG and my medical school does not award an MD degree. My degree is an MBBS. No one in the United States recognizes the MBBS degree. Can I use the initials "MD" after my name?

Before using MD after your name, check with your state licensing board. Many states permit a physician who is licensed to practice medicine in a state to use "MD", even if they earned an MBBS, MB ChB or other equivalent medical degree from an international medical school. Some states, however, require licensed physicians who earned a degree other than an MD to submit a second, separate application requesting permission to use "MD". If you need to use ‘MD’ in more than one state, check with each state’s medical board since policies between state boards can differ.

A recent case in Kansas illustrates the laws concerning use of MD. An oral surgeon who received a doctor of medicine (MD) degree from a medical school outside the U.S. had used the MD initials after his name in his professional practice. The Kansas Court of Appeals and the Kansas State Board of Healing Arts ruled that he could not use the MD initials in his practice because although he was licensed as an oral surgeon, he was not licensed to practice medicine.
