If you call any of these three things your profession, check your calendar now! Are you free December 19? O.M.G. is it too late to become a nurse? I would love to work along side "Kelly Severide!"

"Chicago Fire" is holding a casting call for REAL cops, nurses, and doctors, and this could be your big break!

There are however, a few things you have to do before you become famous. See all the casting call details here.

Good luck, and I'll be watching!
