Thank you for your reply.It was encouraging.I will applying broadly all over the country.I am working on a case report presently in my observership.How else do you think I can work to improve my CV?I would also emphasize to you (and to anyone) that "observerships" shouldn't be an opportunity to passively observe. Try to see patients independently as much as possible, get aggressive with reading up on specific cases, stay on rounds late, write notes, act curious.
Residencies may or may not like your research background, but what WORRIES them is the range of clinical acumen demonstrated by IMG's. Fair or not, the stereotype is that some IMG's are very good, while others aren't. This holds true for everyone, everywhere, in everything, of course, but there is a perceived broader range in effort/aptitude among IMG's, and programs are desperately trying to avoid residents who they perceive as risky.
