TAB Express International provides turbine training (old Kingair A & B90s I believe). They're also starting up their own little airline, using Beech 1900's. You pay the money, they'll train you, then they'll put you in the right seat on of the Beech 1900's and pay you. Once you've built some time, they'll help you get on with a more serious operator.
Some US flight schools offer limited employment after graduating from their program because they are operating under the M-1 Visa program which allows for some type of education-related work programs for a limited time.
Don't be fooled, the M-1 is a student visa only, not a work permit. It is a non-immigrant visa, so they expect you to pack up and head back to where you came from once you're done.
You could stay in the U.S. and attempt to adjust status to a permanent resident, but that requires that you either have an eligible family sponsor, or that you have an employer that is willing to go to bat for you at the Dept. of Labor. With the current glut of qualified pilots in the U.S. that's going to be easier said than done. In the meantime, you'll have to leave the U.S. when your M-1 expires until such time as your immigrant visa is approved.
