I am a medical student. I am planning to go to the USA for my USMLE step 2 CS exam, and applied for a visa on this basis. My visa expires on 30 March 2019.
Recently, I got accepted in Electives Program at Cleveland Clinic, but I have annotation specifically for USMLE step 2 CS on my visa (but no duration) and now I have to take electives as well. I need to be in US for 5 months. I have two options: Should I inform the people at the Port of Entry about the electives, or is it a good idea to skip this information and hope that the officer would give a 6 month stay?
