Lawyers Info

Okay, i am going to study to become a lawyer and someone told me that it can be very useful as a lawyer to be a licensed Bounty Hunter. Why? Can you have a bounty hunter license if you are a lawyer? And what do you have the right to do when you are a Bounty Hunter? Or is it just useful to have a star insignia when you question people? Sorry if my questions are a bit stupid i’m not aware of the laws in the US. I am planning on going there once i finished studying in Europe.
