The due date of my next notification is Sept. 23, so I am now within the window to do it online. However, I am now overseas and returning to Thailand Sept 13. I understand that you need to do notification in person at CW the first time after returning from overseas. Should I do it online now? If so, would next time be 90 days from now, or 90 days from when I re-enter Sept. 13? Or should I wait and do it at CW before (or during 7-day grace period after) Sept. 23? If so, would next be 90 days from Sept. 13 or from the date I do it at CW?
Thank you for your advice.
