Going back to serve home country

Hi everyone, I am an international pre-medical student doing undergraduate here in the states. Now I am applying to medical school and in my essay, I had a line saying I wanted to go back to contribute to the change of medicine in my home country. My pre-med advisor pointed out this could be risky since medical school here are more willing to train students who stay here. What would be the best way to do about it? Any input is appreciated!
