I understand. At times the rules look very stringent and the paper work does seem too much, but that is to ensure that you can take good care of your family when they are here.

to get a visit visa for your wife and child, here are the requirements.

1) passport copy of your wife and child (your name on their passports).
2) your marriage certificate and the child's birth certificate attested by your embassy (if you want them to bring on a visit visa a duplicate copy can be attested by your embassy here but you still need to carry the originals as proof).
3) you need to get your labor contract signed by your employer and submitted to the labor department (this can be in English. You can request your employer to help you and quote a higher salary like 7500 + perks in the contract. Remember not all employers can do it as its a risk for them).
4) no objection certificate from your employer (in Arabic).
5) Your id card and passport copy (including the RP page).

have all these ready and i dont see any reason why the visa would be rejected.
