P-cards will only be issued after the start date of employment.
More regarding P-card policy details are found at: https://www.augustana.edu/about-us/offices/purchasing/policies#4.0.
P-cards are for frequent and ongoing spend less than $2,000. It's recommended to use expense reimbursements initially if you are unable to answer the question with a fair assessment. For one-time spends you would get an advance.
