Maybe someone who actually experienced this can give clear explanation. About the 180 days, is it total stay in Thailand even though we go out after 90 days..so with 60 visa exempt +30 ext, then go out to come back with another 60 + 30 extension, is that it, comprising the 180 days allowed? How long do we need to be outside after this 180 days to be able to come back using the 60 +30 days again? Tia..

Immigration TM30 Notification of Residence of Foreigners

We have been told if you stay in the same residence, you do not need to re-submit every time you go away, as long as it's within a specific time period.

Is this correct ?

What is the time period ?

Many thanks!
