Hello dear !

Yes you are eligible to pursue your masters in forensic science  abroad.you must also meet up the minimum eligibility criteria.

Depending on the mode of admission in abroad

Most universities/ institutions which offer M.sc in forensic science conducts their own entrance exams (EE) and b.sc graduates are eligible to take up the exam.

But some  other universities may even take admissions based on B.sc Mark's.

Good luck!
