after doing llm course we will become a cid officer
Hello Sashi,
By just doing LLM course you can't become CID Officer. You have to write exam conducted by UPSE to fill up the post called as Assistant Prosecution Officer, Legal Advisor etc. You should also enroll for State Bar Council of India.
You have to apply for the exam and appear in the exam. Based on the result you can get the post if you get selected.
Hope this information helps you.
Good Luck!!
