My husband is doing a surgery rotation at the Navy hospital in San Diego, and I have a few questions about per diem and reimbursement. We are supposed to call SATO to arrange his housing and car rental. As I understand it, we use our money (i.e. money that comes from per diem) to pay for his housing and car rental. But we can then submit reimbursements to get refunded for these expenses. Is this correct? Thanks for the info. I really appreciate it!
