Not 100% sure. The prosecutor said that she'd make sure he did his time in a federal penitentiary and that he wouldn't go to a white collar camp. Before he was sentenced he said to Rachel not to worry, it was only a white collar prison. The training Harvey gave him was more for a federal penitentiary (learning how to hit and stuff). He also gave into a plea, so I guess they may have had an arrangement.
I'm not sure which tbh, but he did say white collar camp but when they shown it, it didn't look like a camp with a guard tower with a gun and it barricaded off like that. The judge also said "you have 72 hours to report to [insert name here] federal prison" or something. So...
