Happy New Year all ,

My Son and I currently in Phuket on

A “6 month multiple entry tourist visa”

I am heading home soon , but he is staying for the 6 months to train MuayThai .

Sorry if this is an ignorant question

But as often as it has been explained , we still dont understand the protocol

Do we need to go to immigration before 60 days and then leave country 30 days after that and then do the same process for the second half of the 6 months ?

As in office for the first 60 days , then border run at 90 days and then repeat

Many Thanks in Advance 🙏🙏
