Do I need to do a 90-day report while holding an Ed Visa if no notice is in my passport?

Just to confirm what Ellie stated

When you enter the country on a tourist visa or free stamp entry the 90 day reporting clock doesn't start. 😕

When you get an in country Non-Immigrant type visa for 90 days, the 90 day reporting clock doesn't start. 😕

When you get your FIRST extension from a 90 day Non-Imm visa THAT'S when the 90 day reporting count down clock starts (y)

and

that's when they usually put that paper in your passport saying when your FIRST 90 day report is due)

Like this paper 🙂

So you applied for Non-ED visa inside Thailand and it was approved on 25 March.

The first 90 day count starts with the first extension application usually.

You will need to apply for the first extension at the end of the current 90 days (means around the middle of June). Check your due date on that time you apply for an extension with your local office.

And please remove the unrelated photo from the post. It makes things confusing.
