@Irene Mariam ...
1. If you're interested in studying
forensics, you could consider a pathway related to something like forensic psychology, forensic law or criminal investigative work in the USA or Canada ... if you are not accepted to a medical school program (e.g., MD program).
2. You need to
complete all pre-med prerequisites to be competitive for admission to medical school (MD degree) in the USA or Canada.
3. In connection with
forensic medicine, you could consider work with a coroner's office as a forensic pathologist in the USA or Canada.
4. Stability of employment and stability of income is variable and is often dependent on the scope of your employment, credentials, experience, etc. Just saying although I am
not a forensic pathologist.
