Keep an eye on it. I successfully completed mine last month and it is still sitting at ''pending''. I had to visit the office myself to do the report manually. The officer told me ''Cannot'' when I mentioned I tried to do it online.
A couple of years ago I didn't know about the TM30 and they mentioned it when I went to do my 90 day report 90 days after I came back. Had to go home to get all the details and back again. A whole day wasted. There was no fine though and the next time I left the country my wife called them when we got back and they said we did not have to come to the office and just bring the form when we do the next 90 day report. Nonthaburi Immigration.
Job done, manually, just now. In and out in 5 minutes. While he was inputing the data, I mentioned I tried doing it online and he just said "Cannot" and that was that ;)
Hey all, an update on this. My status is still pending over a week later. I asked my wife to call them and immediately they said you have to come to the office to do the 90-Day report. They said the online system is set up but not yet fully working. So... A 2 hour round trip drive next Wednesday for me ;)
