Just a quick word of advice or my opinion if your travelling to Thailand on visa exempt 30 day entry as your still working (Say offshore) so arriving 6 times a year. So your not breaking any rules, but living a bit on the edge. It may be worth looking at your FB profile. If it says you live in Bangkok and have pictures of my latest 2 cars, thai family, 3 dogs and new build house it my be hard to say you are a tourist, coming on holiday. FB is used to check my things these days, so be careful what you post. Maybe not 100% visa related but sure it will apply to a few on here😉
