Not to belabour the point - I am retired, have plenty of time, so wil make the necessary trip to Immigration.
Just curious - my last "90 Day" Notification was done online on Apr11, 2025. On June 23, 2025, I received an online reminder that I was due to notify again on July 9. I ignored that reminder, because I had been out of Thailand in May, Having reset my 90 day clock upon my return, I decided to use all, or nearly all of the 90 days allowed before doing a 90 Day notification.
Here is my question: If I had responded to the online reminder sent to me June 23, could I have done that online, and thus avoided a trip to the Immigration Office ? (Simply continued on with my stream of prior online notifications, regardless of the fact that I had been out of Thailand for a couple of weeks.)
