Am I limited to the number of credits reflected in the tuition, fees and estimated living expenses documentation?

While United States immigration regulations require that you complete a minimum number of credits per term, you may enroll for additional credits to complete your degree in the time period allotted by your I-20 immigration document.

Undergraduate and postbaccalaureate students must complete a minimum of 12 credits each quarter; graduate students must complete a minimum of nine credits each quarter.
