So, if you’re still with me, here is my advice to you:
1) Like I say to everyone, get the best grades on your prerequisite courses, and get as much good health care experience as you can.
2) Work on your English as much as you can so you can perform well on the TOEFL.
3) Make sure that when you submit your application, your essay has been scrutinized by at least one, and probably several native English speakers. Do this even if you are very confident in your English – a native speaker can always spot subtle cues that indicate language difficulty when reading the work of a non-native speaker.
4) Finally, and maybe most important, rather than hiding your “foreign-ness,” draw from it. As a Malay, I’m sure you have many experiences that US students haven’t, and this diversity factor can help your application stand out immensely, offer diversity to a class, and pique the interest of the admissions committee.
