In the interest of improving Thailands image whoever translates information for them on processes to enter Thailand the word "scheme" is not appropriate. The verb definition of the word "scheme" is: make plans, especially in a devious way or with intent to do something illegal or wrong.
Whenever I see this I think of Thailand doing everything a little bit backwards. Liking changing a lightbulb with three people. One to hold the lightbulb and 2 more to spin the chair. Tell he translator that the word they should be using is process or procedure.
