well , the university is cheap. about working offcampus you can work at lot of places like call center , gas station , resturants etc ..but the thing is u need to use social for this. You get very less jobs where they pay u in cash. The place is nice . Omaha is not a big city but not that bad either. your brother can either stay in omaha or bellevue. Appartments are cheap around $550 for 2 bed which 4-5 people can share.
