Stipend is currently set at $28,000 per year. In addition, students receive a ~$5,000 benefits package which includes medical, dental and vision health insurance plans. Graduate assistantships are only available to US citizens and permanent residents (green card holders).
Texas has NO STATE INCOME TAX, so students enjoy a large financial benefit from living here. However, there is no escaping federal income tax, which all students are required to pay based on their annual income.
