International students face two major obstacles to pursuing an MD degree at a U.S. medical school: limited number of available slots and scarcity of funding. Many medical schools do not accept any international applicants (i.e., not a U.S. citizen or permanent resident); other schools may accept only a few. The AAMC's Applicants to U.S. Medical Schools by In- or Out-of-State Matriculation Status, 2016-2017, notes that of 1,324 foreign applicants within that cycle, only 112 matriculated. International students should consult the individual school's websites or entries in the Medical School Admission Requirements to determine whether applications are accepted from international applicants.

1. Continue to be enrolled in school by prolonging their graduation or enrolling in a special program, such as Science in the Evening or;
2. Do Optional Practical Training. Students can apply for OPT through the International Education Services (IES) Office on campus.
