I sent my USUHS application last week, and it was about 3 days late when I sent it (they ask it to be in 3 weeks after you are notified). I sent an email requesting an extension, which they said to do if it looked like it would take longer than 3 weeks. I have not heard back from that email request yet. It gets more complicated. I sent the application USPS priority mail with delivery confirmation, and it still has not been delivered according to the website (I sent it on the 19th). I am going to call them tomorrow to see if they have received it. How much doo-doo am I in right now?
