If you have ever appllied for a visa before especially in the US or British Embassy , you will understand what I mean by this.
Applicants for visa look so freghtened as if they have committed a crime punishable by death or as someone who went for HIV screening who wonders what the outcome was going to be like.
I happen to experience this when i applied for UK visa, it was unbelievable the way people were looking as if they are that eager to leave the country.
Any, my advice is that applicants shouldnt look that worried instead they should be of good cheer.
