gettin processed in and housing?

when you process in do you get the housing info then and there? and move in right then and there?

When you process in you go through and get your ID and maybe some basic training. After that you have to go to housing and fullfill that area.

What if you don't already have roommates picked out when you get there? Do they just assign you some?

If you don't have a roommate when you get there they will basically assign you a random room. Typically it'll be with people who are already there and need a person to fill out the rest of their room so it's full. It's like playing roommate lottery.
