got it now. Sorry the information on the internet still confuse me a lot. Thank you so much for explaining.
So last question - yes this is what I did. Got stamped in free on a 30 day visa exempt entry + got a 30 day extensions at the immigration office.
If I exit and re enter they will stamp me in on a new free 30 day entry stamp (like they did in the beginning) and I can then get a new extension on that at the immigration?
Basically If I exit I will repeat the process, is that right?
