no secrets i sent a 2 minute voice message on why I got an agent for my situation and especially when I was applying there were a lot of changes to the application and why it was way better to just get an agent. I just didn't want to type a mega message in here.
I am not sure but I think that is for the people that didn't E file. When I went through customs 2 months ago they didn't ask for it. I'm curious to see if they ask for it when i come back into the country again.
