@James *******
Is it fraud when people decide last minute not to work after entry with a Non Immigrant B visa?
Is it fraud to decide not to volunteer after seeing the facilities when you entered Thailand using a Non Immigrant O purpose volunteer?
Is it fraud to decide that the gym is a dump and has no legal and certified trainers after you got the DTV issued?
You may be against the regulation that a visa is valid for 5 years, or until a judge revokes it, or when holder/immigration/Embassy cancel it
But it is part of the regulations.
