It may be getting harder for physicians trained abroad to get good jobs in U.S. healthcare because of a big increase in the number of graduates of American medical schools.

In the past few decades, physicians trained abroad have usually had little trouble finding residency positions that can’t be filled by U.S. graduates.

But  since 2002, 16 new allopathic and 15 new osteopathic medical schools have opened in the United States, and many existing schools have expanded class sizes. By one estimate, U.S. medical school enrollment will rise almost 50 percent in the next few years.
