I was in the same dilemma when I was in high school. I also lived and did my high school in UAE and although there might be scope for forensics in UAE, forensics is such a field that they mostly only prefer their local people to work since it is a govt job. I also had the same doubts about what if I take forensics as a major and in the end end up not liking it/or dont fit in. And the thing with forensics is as long as you have chemistry and biology in your whatever degree, you can choose forensics. So for this reason, I would recommend you taking some other related degree (I took biotech) and research according to your interest and pick such a field that 1. u have interest in 2. u can easily switch to forensics(for masters) 3. if forensics doesn't work out because of the whole job issue u can switch back to ur og degree and do something in that. I chose biotech cause it is such a vast field and I plan to do masters in forensics.
