I left for Indonesia last week and went to ask Immigration whilst I was going through passport control. They told me there is no definite date yet, but they are aiming for early-mid July. They hope the date will be confirmed in the next couple of weeks.
You are playing with fire and should make sure you have contingency plans in the event of being turned away at the border.
Three times in 12 months is the supposed red line, though travelling by air does give you a bit of wiggle room more often than not. This is not universally applied, but you are now relying on being lucky enough to have a border check that is lenient.
If you do a 90d (60+30d) then that takes up 3 months of your visa’s 6m Still with me ?
So then you have 3 months left on your visa. If you take another 60+30, then you have 6m in TH and your visa has expired. Still with me ?
If, however, you just take your 60d and get another 30d extension, BUT exit before the 30d ie in the final week of the visa, and then re-enter you can go for another 60+30.
So, I can see how you can get to 8m and let’s say 3 weeks, even 3 weeks and a few days. It is still not quite 9m. So I am asking people to explain how they get to the 9m - i assume it is leave a return the next day ?
