When you are a TA/CA


Federal regulations specify that you are NOT allowed to perform duties until a valid I-9 has been completed and submitted to the department. TA/CAs who have never performed duties at the university must complete an I-9 regardless of citizenship or visa status. Failure to complete and submit the I-9 and other necessary paperwork to Cindy Walters immediately following accepting the TA/CA position in MICE will result in a delay in pay.

PLEASE NOTE: If you are on a visa type other than F-1 or J-1, CS TA/CA positions are not available to you. In addition, if your country has a tax treaty with the US, please look out for the information that the Payroll Department will send you.

If you are completing a mandatory PhD program teaching requirement, you do not need to complete any paperwork and only have to accept the position in MICE. If you are currently funded as a GRA, you will be paid for TA duties as add-comp and need only to accept the position in MICE. Contact Cindy Walters (cindy [at] with any additional questions.

When selected as a TA/CA, you MUST complete the following within ONE WEEK of your assignment:
