The perks are mostly applicable if you are a native or a naturalized citizen, of course royalty are treated like royalty(if you are working there with sizeable qualifications in a government owned company you can expect more perks than say a skilless construction labor) and nobody is testing how religious you are, this isnt NK where you have to constantly look over your shoulder and count if you have publicly glorified the supreme leader or not, You can be atheist without declaring yourself as such, woman had less rights, but MBS is trying to soften his kingdoms image and its striving towards equality, internet censorship is easily circumventable.

This is all based on what people(who work and immigrated) whom i personally know have told me, but i dont know about closeted or openly queer people.
