finished anesthesiology in India. Are there any job opportunities in Western Europe, Canada, Australia/New Zealand?
+ ecfmg certified. any chances of emergency med/internal med residency in US?
1) You should try the Europe, Canada, and Australia/New Zealand forums.
2) Currently, the Australian and New Zealand College of Anaesthetists (ANZCA) will likely recognize most of the training from a nation like the USA or Canada or UK. But fairly or unfairly, at least to my knowledge, ANZCA probably won't recognize most of your anaesthetics training from India. So you might have to do all your training over again. Of course check with ANZCA, but that's my understanding. I'm just saying be prepared you may have to do your training all over again. (And all this assumes you've sorted out other important things like Aussie permanent residency or citizenship.)
3) Right now EM in the US is hugely competitive for an IMG to match into. You're already an attending, albeit in a different specialty, so maybe that will help some. Maybe, but still no guarantees.
4) IM (if you're open to any program anywhere in the US including "undesirable" locations) is more do-able. There are many good IM programs in "undesirable" locations though.
5) Importantly you haven't said anything about things like your US citizenship or green card status (if you'll need a visa), USMLE scores, US clinical experience, letters of reference, research publications if any, etc.
