Unfortunately, @aunt_bea is right. US medical schools are very difficult for internationals students to gain admission to.
Last year only 121 international students in total were admitted to ALL 158 US MD & DO schools combined. (See AAMC data here: https://www.aamc.org/media/6011/download
and AACOMAS data here: https://www.aacom.org/docs/default-source/data-and-trends/2013-14-first-year-enrollment-by-state-of-legal-residence.pdf?sfvrsn=f6416197_10)
And getting admitted is only the first barrier you’ll face.
international students must demonstrate they can pay 100% of their costs to attend a US med school by placing their estimated costs for at least 2 years of tuition & fees into a US escrow account before they are allowed to enrolled.This means you/your family must pay at least US$250,000 up front before starting med school. (And will likely be expected to pay another $250K for the final 2 years of med school.) There is no financial aid (grants, scholarships) for international students and internationals are not eligible for federal student loans (how US students pay for med school).
tl;dr. Take pre-med out of your school choice decision–unless you’re planning to return to your home country to pursue your medical education there.
