What are the current rules for 90-day reporting after renewing a visa in Thailand?

Your 90 days re sets when you re enter Thailand,entry day is day 1 the IO had to be confused

Okay, here's a fool proof way to know whether the immigration office "reset" your 90 day reporting when you get your yearly extension.

When you get your yearly extension inked in at the immigration office and get your passport back ASK YOURSELF

(𝗦𝗲𝗹𝗳) 𝗱𝗶𝗱 𝗜 𝗴𝗲𝘁 𝗮 𝗻𝗲𝘄 𝟵𝟬 𝗱𝗮𝘆 𝗿𝗲𝗽𝗼𝗿𝘁 𝗿𝗲𝗰𝗲𝗶𝗽𝘁 𝘄𝗶𝘁𝗵 𝗺𝘆 𝗲𝘅𝘁𝗲𝗻𝘀𝗶𝗼𝗻 𝘄𝗵𝗲𝗻 𝗜 𝗴𝗼𝘁 𝗺𝘆 𝗽𝗮𝘀𝘀𝗽𝗼𝗿𝘁 𝗯𝗮𝗰𝗸?

If that answer is yes and you do indeed have a new 90 day report receipt with a new 90 day report date then the immigration office DID reset your 90 day reporting when you got the extension

however

If that answer is no and you did not get a new 90 day report receipt in your passport then the immigration office DID NOT reset your 90 day reporting and you follow the date on the receipt you have.

This works without fail 100% of the time, 🙂 (I mean you either did get a new receipt or you didn't 😛 )

Buri Ram IO resets 90 day when you do extension

If I leave and reenter, I always visit local immigration after return home and they put new 90 paper in passport. Have to report for TM 30 anyway

Is this summary correct?

You had been holding your 1-year extension(s). You entered Thailand on 15 January with a re-entry permit, then applied for a new 1-year extension on 30 January.

Some offices overwrite your 90-day report due date with your 1-year extension application. in most of these cases, you would have a new 90-day receipt or notification with a new due date. At least I understand so.

The best (in the future) is to ask your local office for confirmation of the next 90-day report due when you apply and get a new 1-year extension.
