I was on the investment visa back when it was only 3MB, but later switched to Thailand Elite (1MB) which allowed me to free up funds for investment purposes. Thai Elite now has options ranging from Bt. 500,00 up to 2MB (5yrs to 20 yrs) and you can do whatever investments you like, might be worth consideration.
I think it would be of greater concern IF they tracked us, without telling us....OR, perhaps what we don't know will never hurt us??? Either way, we have no choice, except to leave...
I've been doing that for the past 17 years...this seems to be something new and focusing on those that "arrive" and "depart" regularly via a border crossing or an airport...
