Foreign schools are not "accredited" by the US, per se. However, the State of California "approves" schools for graduates to practice in that state, and a few other states seem to follow along with what they say. Graduates from most schools could practice somewhere in the States, hypothetically, as long as they pass the USMLE exams and complete the ECFMG requirements.

Also, note that California "approves" most foreign language programs in foreign countries -- the difficulty comes if you desire to attend an English language program at a foreign school. California has recently approved Jagiellonian University in Krakow, for example, for their English program (as well as the Polish one, which was already approved). There are other posts in this forum which give the direct link to the California approved list (Ms. Pat Park is the person in the know at that office, apparently). I certainly encourage you to do a search on this site, you will find what you need.
