My son submitted his 90 day address notification online last Friday before the Monday (tomorrow) deadline and it went through but was rejected. What on earth for!!!! Now he has to go in person on the last day tomorrow and stand in the queue a that miserable CW wasting a school day.
TLDR : Answer Summary
The user's son submitted his 90-day address notification online before the deadline, but it was rejected without explanation. Other users noted that there could be reasons for rejection, and informed the user that a representative can submit the report on his behalf. They also mentioned that there is currently an amnesty in effect for 90-day reports until July 31.
