I got my ATT from TN (Fall 2018 graduate). It took 6 weeks and that was only because I kept calling the same lady until she finally investigated why i haven’t received my later yet. It just turned out that the workers were lazy and they gave me my later within that same hour. Also, I know people who applied weeks after you and still got their ATT within 3 weeks from application ! So, there is something that is definitely not right here!! Please, figure out why, and keep calling if you have to!
