It just took immigration 11 days to approve my online request (at CW). From people I have spoken to, this kind of time frame is the norm now. As it is taking longer these days, it's more important to try to do the report at the very start of the eligibility window (15 days before).
Thank for the information. Does that mean you need to file the TM30 after you return from abroad, even if you are returning to the same address? I thought they had relaxed these rules a bit, but it seems that immigration are asking for the TM30 again now. This is for Bangkok.
to add to this - I was told by a few people that the online system would not accept an online 90-day report after a trip abroad because the dates wouldn't match on the online system. However, I was successfully able to do an online 90-day report after a trip abroad.
You should get two documents when you are approved. One is the same as the form you complete in person if you go to immigration and states the date the next report is due very clearly.
It didn't work with firefox for me but did with Chrome. This is to illustrate that the system is temperamental so if doesn't work at first, try a different browser!
I got that message the first time I tried, but I changed browser and it worked the 2nd time. It might be that you are ineligible for online reporting but you shouldn't give up before you've tried with different browsers.
