thehalalpeniswhisperer asked: While on the subject of life in Saudi, do these rules apply to non-Muslim diasporas as well? I was under the impression that there are sizable minorities from the subcontinent and elsewhere who work in Saudi, but didn't know if those women also have to wear abaya.

The abaya is a must for all women. They have to wear black ones. There’s no way around it if they want to go out in public. If the religious police see them in public without an abaya on I believe they can get arrested. The hijab.niqab is optional but the hijab, at least, is strongly recommended for Muslim women in public.

Minorities from other Arab countries, South Asia, Far East Asia, and Western countries actually make up a huge minority as a whole - as much as 30% of the population by some estimates.
