Info on the internet is all over the place. 15 days before and not later than 7 days before, 14 days before and even 6 days after etc. And I remember rules even changed recently.

 

So what it is now for online reporting?

15 days before and up to due date .

I generally set a reminder on my countdown app for 2 weeks before.

I confirm the above. Originally, the window for online notifications was shorter, but you can now use the online app right up to the due date. If after the due date, you must do it in person at the immigration office, but there is no penalty if you do it no later than seven days after the due date.

15 days before online.... 7 days after only in person at the IO

Which is exactly like I do it. But it is not really needed - a least in Korat. The system sends you an email reminder right in time. The service has improved incredibly. This time I applied on Sunday evening, the approvement came by email on Monday about 11 in he morning.

My entry date was April 5th,  basically new report date July 5th,  I went online Saturday June 24th,  12 days before filled out forms thinking weekend Monday or Tuesday  Sunday morning got an email approved.

Being of Irish descent, “ to be sure, to be sure “ works for me.

Admit the service has improved greatly in the last few years but I interrupted its natural flow with a OA to O visa conversion and it took 13 days to get approval last time despite my application in person 1 week earlier.

Now my online and in person due dates are aligned so fingers crossed i will be back on track for online next time .

Use the the 90 report app. It doesn't do the report but does give the dates for all the scenarios.
