Does renewing a visa extension reset the 90-day reporting requirement in Thailand?

Unless the IO provided you with a new 90day report slip to carry with your passport….( as some immigration offices have been reported to do) you will need to follow your origins timeline for filing your 90 day report. Check the due date on your slip……

Renewing an extension does not reset the date…

And

Here's an easy way to tell if your 90 day report reset when you got a new extension

Ask yourself;

When I got my new extension did the immigration officer take my current 90 day report receipt and give me a new one with a new due date on it ?

IF the answer is yes and they did give you a new paper with a new date on it, they did reset your 90 days when you got your extension (y)

IF the answer is no and they didn't give you a new paper they did not reset your 90 day report date and you report when the due date says to on the receipt you got

It is not true for most immigration offices. Check and see if they put any papers in your passport
