I am planning on doing an elective in Temple University, they don't provide malpractice insurance. I am supposed to find it myself, unfortunately I can't find any, tried many places.Medical Liability Insurance also some people call it Malpractice Insurance is a must for any employee dealing or even touching patients in USA.
When look for observership they not only will not give you any salary but they even don't want to pay for you that liability insurance.
Given today's worsening chances of even getting volunteer and observership jobs for IMGs I suggest that you say Yes and you get your liability insurance.
How to get it,
Just Google for Medical Liability Insurance and make sure you check several of them before you choose, prices vary depending on your visa status and the duration of the insurance.
Most of them they have forms to fill online then they'll contact telling you your premium [which mean how much you should pay]
Good luck my friend
