Is possible to work as clinical research being IMG

Hello I would like to know if there is a possibility to start working as clinical research with my medical diploma from my country. Maybe taking courses of CITI Training like Good Clinical Practice and the rest of them and adding in my curriculum. I have the social security and the work authorization but in some websites of the hospitals say that I have to show a bachelor degree in life sciences (I think a field related like biology or public health) OR a related diploma. I don't know if it is possible because I would like to leave my country and start working to prepare for the USMLE Step 1. Thank you.
