docbriarrose,
Obtaining a residency is little more complicated than just contacting hospitals. Since I'm a US Citizen whose main intent is to go back home to the US to practice, I'm aware of the path that one has to tread to get a residency there.
You must take and pass the US Medical Licensing Examination (USMLE) Step 1 and Step 2, the Clinical Skills Assessment, and the Test of English as a Foreign Language.
Grades in Medical School are looked at when you apply to residency programs, but your performance on the USMLEs are also looked at. For more info, check out ecfmg.org for details, or check out pinoyimg.com as well.
You don't have to be a genius to get a residency in the states, however just passing isn't enough as well. You need to know the material.
So good luck in finding a residency.
Also, I'm curious, what school do you go to and what year?
