I am still a bit confused by the rules for TM-47 - 90 Reporting by Mail. Exactly how early can you mail (post) your submission? Is there such a thing as submitting too early? I had it in my head that you must mail it no more than 15 days prior to the due date and no less than 7 days prior to the due date but I don't think that's correct. Re-reading the current info on the Immigration Department website, I interpret it to mean that you must post at least (no later than) 15 days prior to the due date. But I can't see where it says anything about how early you can or cannot mail your submission.
Assuming the due date is 01 SEPT, the deadline for posting it would be 17 AUG. Is this correct?
Is there a start date for the submission window? One month prior? Implied or stated somewhere?
