My son is a medical graduate from India.He has 10 year B1/B2 visa.He wants to come to USA for appearing in USMLE step two CS which can be taken only at USa.He also wants to do observership in USA hospital for two months before coming back to India.I want to know whether he can do so under existing USA laws under B1/B2 visa.Whether he can tell immigration officer at port of entry that he is coming for the exam & observership?Let me know your expert opinion.Thanks
