Guys this requirement of 21 days in the UK prior to travel/arrival in Thailand - They mention  permanent residency as a way of getting round this requirement, now is my Non O visa with a retirement extension classed as permanent residency. I arrived in the UK on 15th Dec and have a return flight on 2nd Jan so only 18 days.

Thanks for any help. 

if you were in Thailand before UK I think there are no issues. But I guess you had your thai pass approved before the end of the Test&Go process right?

If you were here in Thailand count when you started your trip it counts as part of the 21 days.

The 21 day does not matter now unless you are going to able do the test and go that has been canceled unless registered for it already.
