Chronology

18/03/24  New passport received

28/03       Stamps transferred to new passport at Immigration office, and Re-entry Permit obtained

13/04       Departed Thailand

05/05      Returned to Thailand

18/05      Received an e-mail from Immigration stating that my "90 Days" previously done online (using old passport) would need to be done by 03/06.

11/06      Received my annual Extension of Stay, will expire 18/07/25.

 

I am aware that with a new passport, I will need to do my next "90 Days" report in person at the Immigration office.

What is my due date ?

90 days from your last entry to Thailand. 

Ignore email. 

When entering Thailand, 90 days  STARTS on the day you clear Thai immigration.

 

Check to see if you also will need a NEW TM-30 even when returning to same address - it depends on LOCAL office policy.

Your starting date is May 5, 2024 so that means that 89 days later would be August 2, 2024.
