@Jesper ******

read the original question.

It's about the FIRST extension. The 90 day stamp the Non O provided on entry has an expiry PRIOR to 90 days.

When you apply for and extension of that permission of stay immigration treats that as a report clock start.

From then on yes an exit and reentry (with reentry permit) the entry date starts the clock. BTW entry date counts as day one.

So you don't understand that then fine.

Google "does FIRST extension start the 90 day report clock AseanNow"

The visa forum discusses this often.

ok google this... "Does first extension start your 90 day report clock AseanNow"

This is discussed often on AseanNow visa forums..

Fact is when you enter Thailand with a Non O you are given a 90 day permission of stay stamp. If you apply for a 12 month extension immigration "regards that" as a report. Your clock starts from that date.

Note this is really the only time 90 reporting lines up with extension date.

Added confusion is that some offices do a 90 report for subsequent extensions. Offices such as CW do not.

First Extension: When you apply for your first extension of stay (e.g., a one-year extension based on a work permit or retirement visa), this action effectively serves as your first 90-day notification. Your next 90-day reporting date will be 90 days from the date of that extension stamp/approval, not the original entry date.

OP, the above is copy paste from AI. Disregard some poor advice to your question.

The FIRST 12 month extension acts as a report. The first one you will do has due date 90 days from your extension.

You were extremely lucky to be able to open Thai bank account with a DTV which is a "special tourist class visa"

Bottom line is you opened one. Well done.

the author of the OP asked about obtaining COR in Bangkok.

Presumably he will obtain the DTL in Bangkok. An IDP is not required.

@Greg **********

suggest you google the topic on AseanNow. Fully explained there.

@Greg **********

they are not wrong. Obtaining the extension resets the clock for the FIRST extension

@Brandon ***********

fact is an IDP is not required to obtain a TDL. His DL from USA is sufficient

@Darren ********

no. The clock is set when you obtain the extension.

The 90 count starts from when you obtain first extension. Not from when you entered Thailand
