What in god’s name is wrong with Saudi Arabia visa rules.

Need a paper from company in saudi to apply for visa, need a paper from somewhere to go visit my family. What the hell seriously.. Why can’t a person just take all the necessary documents to show what purpose he is going for and submit. It is just very inconvenient and on top of that they stop issuing visa when it comes near Haj Time or other such occasions. For the love of god, why would a person cheat get a visit visa and then go for Hajj or something, after all isnt the whole point going for hajj etc is to ask for forgiveness. JEEEEZZZ!!!

True that i am not a gulf national but i do hold a Management Level Visa which allows me to get visa on arrival.

Dubai Check.
Kuwait Not Check. (post to follow)
Qatar Check.

Most of the GCC countries allow me to get visa on arrival except saudi, This is kind of annoying. Now i need to get a letter from some company in Saudi so i can have my visa processed before 11th of november to join an exhibition there. Any Ideas People??
