How feasible is it really to apply to MD-PhD as an international student?

As the title says, given that most MSTP schools either don't accept any international students, or accept anywhere from 2-5 per program, how feasible is it to apply? Especially with cuts to research grants making schools decrease the size of their programs.

I am a junior international student with 2000 hours of research (planning on 3000 by graduation) with 2 publications coming up, taking MCAT this cycle and 500 hours of clinical volunteering plus leadership experience in clubs. Also planning on getting an EMT certification to get my clinical hours during my senior year when I hope to apply for MD-PhD. Any thoughts on whether it is worth it with these stats (or worth it for an international at all)?
