I dont know in which year of your med education you are, but in general after 2nd year USMLE Step-1 is taken. If you are not a graduate, you may try to have a couple of months of clinical experience in US, which has a serious contribution in residency match after you graduate. During your USCE (US Clinical Experience) you can have some LORs from US MDs as well which is also important for residency match. One more point: USMLE Step-1 score is pretty important to find a place for USCE and for resindency match again. So you need to get prepared very well for that test, and you can do it by purchasing sample tests as many as you like from NBME, the institution which prepares USMLE tests:

There is a "Sample Assessment" link on the left of the page, its free for a first self assessment.
About clerkship and electives this may give some idea:

An old thread, but gives an idea about some elective programs for international med students:

edit: If you want a place in which doctors are cherished and respected, US may be a wrong place for you. The US MDs too are unhappy with the strict regulations which make them feel a heavy hand over them. You may feel better among rather warm people like Turks(I am a Turk as well) or Poles. Both countries have upward trends in their economies, social developments etc, and its interesting that Poland has good indicators
despite the situation in EU. That goes for Turkey as well, despite we are not in EU and cannot export to Europe as much as before the EU crisis, still Turkey has the 2nd highest growth rate after China in 2011.
Anyway, I was considering to work in US, but I changed my mind, I see that I cant breathe among them. If you want to live among people who knows to value each other, you must pick a society which is conservative in some social values like Turkey, Poland, maybe Japan and Canada. For Canadians too I hear that they are way more humane than Americans. But definitely not USA.
