Clarify!!!
dude, easy with the exclamation marks. are you looking for help or demanding it ? ;)
why would you want to wait until the last day? what if they say that it is the receipt date? it won't be fair, but what would do in that situation?
if i were you, i would get all the documentation ready latest by Thursday and mail it using overnight service, so that i have a delivery date before the 15th.
