How to become a detective after College?

Question

I'm currently a freshman in John Jay University of Criminal Justice, Majoring in Criminal Justice Administration and Planning (BS). I've just been slowly planning my future along the way but I was wondering after i get my degree how do i become a detective? Some have told me I have to Start as a PO and join an investigation case for 18 months and then the city will have to promote me to Detective. Is this true? I would like to hear from real police officers and detectives ( or people with experience.) Thank you in advance.

Update:

I also forgot to ask, With this degree I can become a Detective right? And it will substantially help in promotions correct?

Detectives are now called Investigators.  They are promoted from within the department.  It usually takes 3-5 years on patrol before you can apply to be promoted to Sergeant.  After becoming a sergeant you may or may not be an investigator, depending on the department.  It may take more time from there to have enough seniority to get the position.

Well I can tell you how it is out here in Dallas. In Dallas you graduate the academy and after a 2 year minimum in patrol you may qualify to take your Sr. Corporal test, the higher your score the higher ranked against other officers who took the test, if you get promoted then your opinions open up you can join any division if they have an opening available, and sometimes you may have to take a test for them or even tryout for the division. But they usually are always looking for detectives good luck.
