I have done B.Com in corporate secretaryship. Which field / course do I have to study human rights?

You can go for a PG Diploma in Human Rights or an M.A. in Human Rights, because these courses are open for any stream. 

After B.Com in Corporate Secretaryship, you can study Human Rights through:

• PG Diploma in Human Rights

• M.A. in Human Rights

• Certificate courses (e.g., from IGNOU or NHRC)

No specific stream is required—any graduate can apply.
