In regards to Visas for Spouse or Fiance/Fiancee, It would not cost our government $1 more to do the Visa Interview in a Professional and Fair manner.
There is very little information as to the "Real/Actual Requirements" on Visa Interview Policies, only the VAGUE guidelines, that a Visa Interview Officer may or may not use. Obtaining a Visa SOLELY rest with the Visa Interview Officer's DISCRETION, which means, "ability to make a responsible decision". "Solely" means an Interview is not Responsible to anyone or any laws or regulations. In reality, "Sole Discretion", means "Personal Opinion". This policy leads to wide spread discriminations, and unfairness.
