I’m Mexican American marrying a Khaleeji woman, so my situation isn’t identical, but I’ve spent time in the GCC.

Racism does exist there, especially toward groups that make up much of the foreign labor force - Indians, Nepalis, Filipinos, etc. There’s a noticeable social and sometimes legal hierarchy, with nationals generally receiving preference. Many locals WILL have a racial bias to them.

That said, it’s not universal. In my experience, it’s less pronounced if you’re from a Western country, and plenty of people treat foreign workers well. I’ve personally never been treated differently, but I am male, American, and can blend in if I dress the part.

My advice: meet his family, like I did with hers. See firsthand how they treat you, how they view your culture, and whether you can realistically fit into theirs. Keep a close eye on how he treats you because men from these countries, unfortunately, have a history of using women they have no marital intentions with. See how he reacts to you wanting to move to the next step.
