Hi Bessy-
You may contact the Fort Worth alumnae panhellenic for assistance, however I would do so ASAP. They list May 1 as their preferred deadline.

While many students at TCU are involved in Greek Life, I will say that the International Student Assoication is also very strong there. You will have many opportunities to get involved on campus whether or not you decide to go through recruiment.
Best of luck to you and Go Frogs!
