Hey,

To be vey honest both the streams are related to biomedical science but with a slight difference. MBBS is more like a medical field that involves working with patients to treat or cure them.

On the other hand biotechnology helps one to design solution that helps MBBS or doctors to treat or cure patients.

If you are someone who feel like working between patients and help them in getting treated you should for MBBS but if you like working in isolation in the laboratory you can pursue Msc Biotechnology.

The country to be very honest doesn't matter. The only thing is that after MBBS you need to sit for an  entrance test to become eligible to practice in India. That's not the case with Msc Biotechnology.

Think wise what you want as per your interest and the time you want to give for that.

Hope that helps

Thank you
