So I applied 4 weeks ago for a 90 Day Non O ( Retirement based )

I was stamped to return today ( 24th April 2025 ) to get the Visa stamped in the Passport ( under consideration period  - 4 weeks )

 

What I learned today was that the application was processed on 10th April 2025

 

What I learnt today is that the 90 day visa starts from the date of Processing!

 

So the 90 Day visa actually expires in about 76 days time from today!

Not  a big issue - just the first time I have seen Thai Immigration not start the new Visa from the Expiry date of the previous valid visa....  

You applied to "convert" to a new visa type.  Whenever you are changing visa categories, the time is not added to the end of your existing stamp.

The period of stay starts from the day the application is approved, when apply for the Non O, or when changing the reason for an extension.
