Your visa is valid for up to five months after you leave the country. If you have been out of the country for these three months, you may not need to apply for a new one, but UT often recommends that students who return home for an extended period of time before starting a new program go ahead and apply for a new visa. You may check with your new school and see if they have a recommendation in that regard.
