Yes, G1145 is the form. I explicitly added that to the set of forms. However, all it means is that application is picked up at the drop box and a case no is assigned to it. Once this is done, the next step is the receipt notice. If you check gets cashed out, that would indicate the receipt notice is on the way. I think it might happen by end of this week or next week
From there on, its just queue and wait.. I also use the "watch case" feature of trackitt and it helps me keep updated about others..
@gautha -- thanks for the good comments.
