I am a student from Australia who was admitted to Amherst and Rice. I’m looking to apply to MD/PhD programs in the future.
Internationals are at a very severe disadvantage when it comes to MD/PhD programs. This is because the vast majority of MD/PhD funding comes from the NIH’s MSTP program (Medical Scientist Training Program) --which requires all grant recipients to be US citizens.
Last year only 10 international students were accepted into all US MD/PhD programs combined.

If you are willing to pursue a PhD only, you will have a much easier time finding an acceptance and funding.
