I heard doing research improves your chances for matching
can any one please explain what type of research to be done and how (an example would be really helpful)

I am preparing to appear step 2 at first.. Is that a good Idea.. Or should I focus on step 1

And please I graduated from KSA... Can any one say me what requirements do I need to work as a general practitioner in US.. And what are the things that may improve my chances.. Want to know.. If by chance I don't get chance for residency

THANK YOU
