Is it possible to work here in Riyadh as an Expatriate Dependent?

How can I work in Riyadh part-time/full-time as an Expatriate Dependant, under 18 years of age?

try mcdonalds, or any western type fast food chains.

No I think you will fond it hard..to work at that age..i remember. Something from a few years back .new rules.about the age
And also its getting harder for foreigners
And even fast food places are trying to employ saudis
