Let’s see the things as clear as they are - many people are now just paying to someone, let’s say in Vietnam or Laos, or anywhere in South-eastern Asia, to prepare all the paperwork and apply for a DTV visa on their behalf. Once received the visa, those people believe the country officials don’t know about these schemes. This damages the efforts of those who have all the paperwork prepared by themselves and where all the documents were real. And this explains the tough stance of the immigration authorities and their unwillingness to accommodate you, regardless of whether you received your visa fairly or not.
