Well,

I graduated from Lindenwood last fall. I don't think Lindenwood allows student to stay off campus. If u stay off campus, you will lose your "work and learn scholarship" and you will end up paying same. I would suggest your brother to live on campus.

Is your brother coming for grad. school or undergrad???

By the way this is Spellman center. It includes, Cafe, Computer lab, Mail room, FM station ( i think they moved to different building), student development center, international office, and a nice view of Hunter Stadium (football). And of course a clock tower, where every wednesday night( i guess), there will be couple of student, singing something ( god know what they are singing, but they are singing).
Tell your brother to work ("for work and learn scholarship") at cafe, that's the only place for issusing ssn.
