@Lynda *******

there was actually no need for you to have spent money to apply for the tourist visa, as it only grants the same 60 day stay (+30 day extension from immigration offices in Thailand) as visa exempt entries for UK passport holders. It serves no purpose to normal tourists since they changed visa exempt entry from 30 to 60 days in mid-July.

@Han ****

yes, first one per entry must be done in person, then you can register to submit future ones online.

@Han ****

The form is not called TM90. It is actually TM47. The name is the government form number. It doesn't have anything to do with it being due every 90 days.

@Chris *******

I don't think you know what use of the term ETA they are referring to. It doesn't mean estimated time of arrival in this case.

@Łukasz ********

then you have a stay permit. What do you think your visa is?

@Łukasz ********

If you entered visa exempt or via tourist visa, you can only stay 90 days anyway even with an extension, so you must have some other way you entered that is allowing you to stay longer than 90 days, therefore requiring the 90 day report. If you are planning to illegally overstay for 5 days, then the 90 day report is the least of your worries.

@Łukasz ********

you can do it a week before. You don't have to do it on the actual 90th day.

@Łukasz ********

yes

Make sure you know the difference between a TM30 and a op day report. TM30 is required within 1 say of arriving at any address in Thailand to stay overnight, and is done by the homeowner to advise the government that a foreigner is staying there. Hotels do this each day for guests that check in that day. A 90 day report is a self notification that you must inform immigration where you are staying every 90 days you remain in the country. If you exit, the 90 days resets to count from your next entry date. You need a TM30 (initial report of where you are) to file a 90 day report.
