Each campus has variations in submitting cost reimbursements
It can be assumed that receipts for all expenses will need to be submitted. It is important to discuss this with your program. The controllers office at your campus has final say in what will be covered, ensure that there is clear communication. Will they cover costs incurred for phone and computer access? What is the per diem rate in the areas you will be staying? Does your campus have an app for submitting receipts as you travel? Do you need to submit hard copies, only originals?
