After having my application make a round trip to Phoenix once in vain, my obsession with tracking whereabouts of my N400 has intensified. The second time I sent my application, I diligently included G-1145 form with my mobile number and email address. 5 working days have elapsed from the day FedEx delivered my application, but there's no TXT message nor email. I was hoping that it would take them 2 working days before generating a WAC number for my case. Is it too early to expect these messages?
