I use an Android app (90 days report) to calculate the correct filling dates.
The online date for online filing is given by the app as:
Arrival day Jul 12 (regturn from overseas trip)
Due date October 10
In Person Sept 26 -- Oct 17
Online Sept 26 -- Oct 10
When I manually count the dates, I get dates that are one day off.
Could someone please verify my math
