Why don't students of peripheral AIIMS prepare for USMLE, unlike AIIMS Delhi students?-

First of all, it's untrue that students of other AIIMS need to clear USMLE and move abroad for higher studies. In my sister's batch 5–6 seniors cleared USMLE from AIIMS Bhopal and moved abroad. However, the number of students going abroad from other AIIMS is certainly less than in AIIMS Delhi. Here's why

• AIIMS Delhi students are entirely guided by their well-placed alumni in foreign countries while the students of other AIIMS have no one to guide them. 
• IIMS Delhi provides a perfect environment to move to states for further studies owing to its excellent research opportunities and faculty recommendations.
• It's the AIIMS Delhi tag that enjoys global recognition and not all AIIMS have been able to reach the global market.

However, over the past few years, there is a significant decrease in the number of AIIMS Delhi students moving abroad after MBBS. I think the major reason for this change is that India now provides excellent academics and opportunities in medicine that are on par with global standards. Ultimately it's the individual's choice to clear USSMLE and go abroad or stay in India and do their PG from AIIMS.
