hey there,

first of all, it dosen't matter what is your job description on the id card or anywhere for the matter..

u do need to have ur certificate with you which helps you a lot, but even if u don't its still isnt a problem..

about ur minimum salary.. the minimum is 8000 ryals, and u must have ur company has been depositing ur salary in the bank account for a period not less than 6 month, it might work by 3 month if u know someone but the procedure is 6.

you will also have to provide a copy of your work contract, ur id of course, copy of passport of ur wife , copy of lease of ur home contract, and last electricity bill ( dont really know if there is something missing )

then in case ur application got rejected u can apply for a meeting with the commitee of acceptance, if u go there they will ask you about where u live, ur university degree, and salary ( simple stuff)

there is a specific criteria that u need to get accpeted, my advice get someone who knows about these stuff from ur company or any other place and let him help u with it.. its the best way.. if u do it urself and u get rejected u cant apply before 2 month for a second application.

take care and i wish u luck
