Actually, I remember when mine was processing earlier this year and it stalled I called and got someone who discovered the person who had mine was "on an extended vacation." Once someone has an application assigned to them nothing happens if that person drops the ball on that application - and it happens constantly (not occasionally, constantly).If you are thinking of mailing off your CHL stuff heres my philosophy: mail it off and forget about it. It will come someday
If your application stalls you need to call and check on it until something happens with it.
